Technology can be exciting, flashy, and neat – but is it always necessary? Hundreds of thousands will stand in line for hours for the newest smartphone. They spend a lot of money and time making sure they have the most recent upgrade. And this desire for new technology isn’t exclusive to cell phones and computers, people want the latest equipment in most areas.
In the Home Inspection industry, one of the more advanced pieces of technology that can be used is an infrared camera to complete Thermal Imaging Inspections. But is this tool and Thermal Imaging Inspections really worth the hype, or are people just fawning over the latest gadget?
A Thermal Imaging Inspection is a non-invasive process that uses an infrared camera to measure and record the surface temperature of materials. Although this technology does let you see more than the naked eye, it is not x-ray vision and will not let you see through walls. Instead, infrared cameras capture images that use a colour scale to show temperature differences on surfaces.
At Carson Dunlop, we understand that water leakage is a significant concern for our clients. In fact, over 35 years, we have learned that water is the single biggest enemy of homes. This is why we have tailored our Thermal Imaging Inspections to look for concealed water problems. During our Thermal Imaging Inspections, our Home Inspectors will use infrared cameras to look for hidden moisture in the most vulnerable areas, with specific focus on basements, areas around and below doors and windows, and ceilings below roofs and bathrooms.
Infrared cameras allow Home Inspectors to look beyond physical elements. Homes that appear perfect can have significant issues – you just have to know where to look. For example, while performing a New Construction Inspection for a client before their Tarion Warranty expired, we used an infrared camera to investigate the ceiling below the home’s whirlpool bath.
To the naked eye, the ceiling looks immaculate: no staining, no bubbling, no indication of any problems.
However, with an infrared camera, the leakage is clearly evident.
Our moisture meter confirms the presence of water in the ceiling, saving the new homeowners a lot of hassle.
Imagine how bad this leak could have become! A whirlpool tub holds a lot of water. There was no visible evidence, but we discovered the problem during the Thermal Imaging Inspection. (It turns out that their neighbour also had a leak under their home’s whirlpool tub. But they found it the hard way).
New technology is not always worth the hype, but in the case of infrared cameras and Thermal Imaging Inspections, it is. We can’t tell you whether the next smartphone will be a great investment, but we know that a Thermal Imaging Inspection is. To learn more, please click here or call 800-268-7070.


The functions and applications of vortex air pump are very rich, among which the functions of both blowing and suction are very familiar to all of us. Therefore, there are many people called vortex air pump, which is also called side channel blower and flow measuring fan in foreign countries. Many terms are felt by the application occasions, but they are actually a product.
Using in the laser equipment, is to take advantage of the product's high negative pressure, high flow, lightweight structure, low noise, oil-free maintenance free and many other traditional vacuum pump incomparable characteristics. As a result, it is used more and more widely in the field of laser equipment. Laser is a new light source in 1960s. Because of its good directivity, high brightness, monochromatic, narrow frequency range, and can concentrate high energy in a narrow direction, it is widely used in the automatic processing of various materials. Now the developed laser technology is mainly used in rapid prototyping, cutting, welding, carving, drilling and other metal or non-metallic materials processing.
High efficiency automatic laser equipment composed of laser technology and computer numerical control technology can be divided into YAG laser marking machine, semiconductor laser marking machine, CO2 laser marking machine, optical fiber laser marking machine, laser engraving machine, laser welding machine, laser cutting machine and laser dicing machine. The working principle of laser equipment is basically the same: the graphics to be produced are traced in the computer through the computer software CorelDRAW or other software and stored in PL format. When the PL file is opened with the special software for laser equipment, the graphics of the file will be displayed on the screen; the equipment can mark or cut the material according to the graphic file of the computer.
Vortex air pump is the core component of laser equipment, its quality directly affects the quality of finished products. Therefore, there are special vortex air pumps on laser equipment. The vortex air pump uses negative pressure adsorption, and its specific role in laser equipment is roughly similar. Take laser engraving machine as an example: in the cutting process of laser engraving machine, rubber plate or paperboard should always keep original The position, can't move, otherwise come out of the finished product in accuracy and precision will have problems, vortex air pump here plays a fixed rubber plate or cardboard role. The suction generated by the vortex air pump (side channel blower
) is used to fix the object to be cut, so that the object to be cut is not offset in the cutting process, so as to ensure the accuracy and precision of the cutting height and improve the working efficiency.

Whereas aesthetics has primarily driven the pace of change in decorative lighting designs over the years, rapidly advancing technology has become equally important in ensuring specifiers are working with the most up to date products. Chelsom operate rigorous testing procedures to select the best performing LEDs and work only with the most reputable LED chip and retrofit lamp manufacturers. When testing and selecting LED chips, the following criteria are considered:
At Chelsom factories in the UK and China, continual investment means the latest manufacturing and testing equipment drives on the quality of the product. In-house photometric testing guarantees colour temperatures and Colour Rendering Index (CRI). Operating in the global marketplace, Chelsom wire and test to all international standards ensuring access to every international market. Both our UK and Chinese factories have the international approvals shown right and are regularly audited to ensure continuous compliance.
Although the standard Chelsom range offers a wide selection of integral and retrofit LED light sources, Chelsom also have significant bespoke capabilities allowing conversion of standard light sources to bespoke technology requirements to match the more complex dimming systems. For example, Chelsom can operate with colour temperatures ranging from 2200K to 4000K and with 80 to 95 CRI.
To ensure optimum ambience within any interior scheme, light levels should be controllable through dimming systems. Dimmable lamps can be operated from rotary dimmer switches within the product itself or from remote wall-mounted control panels. There exists an extremely wide range of lamp dimming protocols but the crucial issue is ensuring compatibility between lamp type, control gear and the dimmer itself.
Chelsom are experts in creating successful dimming, constantly researching new methods and technologies to continuously improve the technical offer. For standard products, Chelsom will have carried out thorough long-term testing to ensure optimum lumen output, best lifetime performance and minimal heat output. For bespoke designs, the Technical team work closely with clients and ask the right questions to ensure full understanding of any dimming protocols on site so that Chelsom product is entirely compatible from a lamp type, switching and flicker- free dimming performance perspective.
Lamp technology has developed possibly faster in the last 10 years than at any time since Thomas Edison invented his first electric light bulb. Chelsom constantly embrace the latest developments to ensure the hospitality an marine markets work with the most energy efficient an aesthetically pleasing light sources. Today’s lamps use 90% less energy than old incandescents, last up to 25 times longer, give off almost no heat and significantly reduce maintenance costs. The latest retrofit lamps from Chelsom have almost 360 degree light output and a 2700K warm white colour temperature with instant start and good dimmability, compatible with both leading and trailing edge phase dimming controls.
Retrofit LED Filament
Filament lamps are now available with LED light sources. Chelsom offer very high quality options with 2200K colour temperature meaning the ambience is indistinguishable from original incandescent options. Lamps are dimmable with trailing edge phase dimming controls and interesting lamp shapes combined with a soft glow of light have ensured the popularity of filament lamps. In Edition 26, several collections are priced and supplied complete with filament lamps where they enhance the decorative appeal of the original designs.


Schematic structure and demonstrator of the optoelectronic absorption and fluorescence sensor
When ecosystems are stressed by the release of chemical substances, the effect of the various possible combinations on living organisms is still largely unknown. While the toxicological effect of individual substances is usually quickly recognized, the number of possible mutual influences increases sharply with the number of substances. The project “Optoflutronics” as part of the ongoing BMBF joint project “Competence Triangle Optical Microsystems 2020” (OptiMi2) aims at the efficient investigation of the combination effect of potential active and harmful substances. An efficient analysis of the toxicological parameter space can only be realized by consequent application of system integration in the sense of a combination of microfluidics, microoptics and microelectronics.
In this context, the CiS Research Institute leads the development of a micro-fluorescence sensor. In a multi-channel sensor, optical excitation with different wavelengths of light and measurement of transmission and fluorescence signals take place. The sensor is based on the combination of narrow-band high-efficiency light-emitting diodes, optical interference edge filters, micro-precision optics and highly sensitive photodetectors. The sensor is designed to detect a wide variety of fluorescent and absorbing substances in segments as small as a few nanoliters, which pass through the sensor at speeds of several centimeters per second within a fluidic channel.
The highly sensitive measurement requires sampling rates of several kilohertz and signal amplification directly on the sensor.

Anti Fog Spray, 15 milliliters ZEISS lense, glasses, glass Sports, Fitness & Outdoors
Every glasses wearer is familiar with lenses fogging up: whether from wearing a facemask, stepping from a cold environment into a warm one or just consuming a hot drink.
ZEISS AntiFOG Kit combines a spray and cloth which, when used together, can be quickly applied to both sides of the lens and provide up to 3 days of defence against fogging.
AntiFOG Kit contains:
- 1 x 15ml AntiFOG Spray
- 1 x AntiFOG Cloth (5in x 5in / 13cm x 13cm)
- 1 x Portable pouch for convenient storage
How does ZEISS AntiFOG Kit work?
Using ZEISS AntiFOG spray and AntiFOG cloth together on your lenses results in the application of a thin hydrophilic film – comparable with a temporary additional coating – on the lenses. This ensures that fine, condensed water droplets do not accumulate on the lens surface causing fogging. Due to the hydrophilic coating any moisture spreads out on the lens to form a thin even layer that does not impair visual clarity. Thanks to the cloth, this process is quick, gentle and does not damage the lens coating. If the lenses need to be cleaned again it is recommended that you repeat this lens care process using ZEISS AntiFOG kit to ensure optimum protection against fogged-up lenses.
Testing carried out in 2020 at Aalen Group Test Center
ZEISS AntiFOG performance was verified by performing the following 4 tests:
Test 1 – Optical Clarity
A lens treated with ZEISS AntiFOG is examined to ensure its retained its optical clarity.
Test 2 – Huff Test
Three large exhales of air are applied directly to a lens treated with ZEISS AntiFOG to confirm ZERO fogging.
Test 3 – Cold to Room Temperature Test
A lens treated with ZEISS AntiFOG is taken from -5° C to an environment of room temperature (25° C) and confirmed to show no fogging.
Test 4 – Warm Mist Longevity Test
A lens treated with ZEISS AntiFOG is held directly in a 50° C warm mist stream and confirmed to resist fogging (as per ASTM F659 standard). This is repeated five times a day for 3 consecutive days to confirm up to 3 days fog free vision.


Marking by discolouring the surface of a component or by precisely removing paint.
Very much as it sounds, a precisely controlled laser beam is used either to discolour the surface of a component or to vaporise material. The laser parameters and the laser’s position can be precisely controlled to provide high contrast marks in the form of barcodes, logos and graphics.
If a surface is painted then the laser can be used to precisely remove paint. By choosing a translucent substrate that is a contrasting colour a graphic can be backlit for night and day readability.
Common materials that are laser etched include anodized aluminium, coated metals, foils and films, or laminates and painted plastic components.
Such process is used widely in the automotive and aerospace industries on backlit buttons and also by the general manufacturing industry on coated metal components.


The diameter of a single mode core is 9µm. Both fiber types have a cladding diameter of 125 µm or microns The two main parameters are Coating Diameter (Uncolored) 237 - 247 μm and Coating-Clad Concentricity Error of max. 0.5 micron. For roughly the first 30 years of single-mode fiber manufacturing, a coating nominal diameter of approximately 245-250 μm was standard in the industry .g. for high-power devices or for multi-core fibers with a larger number of cores. Many fiber tools such as fiber strippers and fusion splicers are optimized e.g. for the 125-μm standard cladding diameter and may then not work well for non-standard fiber diameters The typical core diameter of communication single mode fibers is from 8~10um for operating wavelength 1.31um to 1.5um. Fiber with a core diameter less than about ten times the wavelength of the propagating light cannot be modeled using geometric optics as we did in the explanation of step-index multimode fiber A typical single-mode optical fiber has a core diameter between 8 and 10.5 µm and a cladding diameter of 125 µm. There are a number of special types of single-mode optical fiber which have been chemically or physically altered to give special properties, such as dispersion-shifted fiber and nonzero dispersion-shifted fiber.Data rates are limited by polarization mode dispersion and chromatic.
Left: Single Mode fiber is usually 9/125 in construction. This means that the core to cladding diameter ratio is 9 microns to 125 microns. Multimode Fiber Optic Cable Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate Since MFD value for single mode fiber does not really exceed 12 microns typically, why is the cladding diameter still 125 microns? Is this due to optical reasons or more to do with mechanical strength and processing methods? Answer from the author: Considering only the optical performance, the fiber diameter could indeed be much smaller. However, such extremely thin fibers would indeed not. For single-mode fiber, the mode field diameter is larger than the physical diameter of the core, because the light penetrates slightly into the cladding as an evanescent wave. The three most common core sizes are: 9 μm diameter (single-mode) 50 μm diameter ; 62.5 μm diameter (multi-mode) See also. Buffer (optical fiber
Although the cladding possesses six-fold symmetry, the mode profile is very similar to the quasi-Gaussian fundamental mode of a conventional, axially symmetric, step-index fiber, resulting in a form overlap that is >90%. Unlike conventional fibers, these fibers are fabricated from a single material - undoped, high-purity, fused silica glass For single-mode fibers, the evanescent field must also be considered, particularly when the fiber is to be coiled/bent. A general rule is to keep the cladding diameter greater than 8-10 times the mode field diameter of the fundamental mode
How reducing cladding diameter changes size of single-mode fibers with 10 µm cores. Standard fibers have an outer diameter of 125 µm, which is thick compared to the 10 µm core of single-mode fiber. It's possible to reduce the cladding diameter to 80 µm, which reduces the glass volume of the fiber by a factor of 2.4. A reduced cladding fiber with a plastic coating has an outer diameter of. Single Mode (SM) vs. Multi-Mode (MM) Fiber There are a few factors that contribute to the type of mode propagation a fiber will demonstrate. These factors ultimately make up the fiber's V-number that determines which modes propagate in a fiber. These factors include: indices of refraction of core and cladding, core diameter, and wavelength. Single-mode fibers are etched to reduce the cladding diameter from 125 to 15 ॖ m . A 2-ॖ m -thick silica layer is grown in the silicon substrate to minimize the fiber-substrate coupling. Reduced diameter fibers are placed into a 5- mm by 150-ॖ m trench etched in a silicon-silica substrate and fixed with UV curable cement. Active alignment.

Illustration of the dispersion relations of the core optical mode of a single-mode fiber in both directions, a cladding mode in one direction, and an acoustic mode excited by backward SBS between two counterpropagating pump waves in the core mode Single Mode (SM) and Multimode (MM) are the names given to two competing designs of optical fiber based on how many paths of light are transmitted along the fiber core - single mode, meaning one path, or multimode, meaning more than one path. A mode can be described as a path or ray of light in the core of the optical fiber Single-mode Only the fundamental zero-order mode is transmitted in a single-mode fiber. The light beam travels straight through the fiber with no reflections from the core-cladding sidewalls at all.

Dimensions of the single-mode and multi-mode fibers, the single-mode, and multi-mode fibers have core diameters of 9 μm and 50 μm respectively. In optical fiber technology, single mode fiber (SMF) or monomode fiber, is an optical fiber that is designed for the transmission of a single ray or mode of light as a carrier to propagate at a time. Generally, single mode cable has a narrow core diameter of 8 to 10µm (micrometers), which can propagate at the wavelength of 1310nm and 1550nm. In a single-mode fiber, all signals travel straight.

Custom single-mode configurations, including pure silica core or custom wavelengths, may requir The usual fiber specifications are size (core/cladding diameter in microns), attenuation coefficient (dB/km at appropriate wavelengths) and bandwidth (MHz-km) for multimode fiber and chromatic and polarization-mode dispersion for singlemode fiber. While manufacturers have other specs for designing and manufacturing the fiber to industry standards, like numerical aperture (the acceptance angle.
base of standard single-mode fibers such as SMF-28e+ fiber. SMF-28 Ultra fiber offers industry-leading specifications for attenuation, macrobend loss, and polarization mode dispersion values, which provide a solid foundation for new network deployments as well as upgrades to existing networks. Since Corning brought the first fiber to market more than 40 years ago, Corning's leadership in. Segmented cladding fibers were fabricated with PMMA polymer. Single-mode operation at 1.55 /spl mu/m was observed with a 36.5-cm long fiber that consisted of 4 cladding segments and had a core diameter of 20 /spl mu/m The multimode nature of large core diameter terahertz fibers has to be suppressed by tuning the antiresonant tubes to act as a single mode fiber in the whole transmission region. The metal wires maintain the optical properties of refractive index and mode field pattern, while lowering the confinement loss. This work, aiming at improving the loss performance of terahertz waveguides, finds that.
Fiberguide's Single Mode Fibers are used in data transmission applications as well as photonics applications where a single optical path, or mode, is desired.

We show the design and applicability of multi-core fiber (MCF) with the standard 125 μm cladding diameter to the telecommunication systems. It offers easier and practical use of the space-division multiplexing (SDM) technology given its excellent fiber productivity and utilization of existing standard technologies. We numerically and experimentally reveal that the simple step-index (SI. Fiber Bragg gratings (FBGs), which consist of a periodic modulation of the refractive index in the core of a single-mode optical fiber, are widely used for optical communication devices, temperature sensors, and distortion sensors. 1) In addition to FBG sensors, tilted fiber Bragg gratings (TFBGs) have recently been attracting considerable attention for their use in sensing applications. 2. We assumed this fraction to be equal to 90%, yielding a cladding hole diameter of 1.76 µm. The index spectrum of the fundamental space-filling mode (taken to be the cladding effective index) of the water-filled cladding was numerically obtained and is shown in Fig. 1a (blue line). As values are ~1.36, the fiber may present single-mode guidance in liquids, such as ethanol, that present indices.
A technique for determining the cladding diameters of single-mode optical fibers, using the fringe profiles in an interferometer is proposed. When the Lloyd's mirror arrangement is used it is possible to obtain fringes from rough surfaces. The possibility of automating the measurements is discussed along with imaging of the fiber tip and its reflected image Generally, this path difference is made by combining different types of optical fibers, for example, multimode with single-mode [4, 5] or single-mode with microstructured , tapered two-modes [7.
V - number determines how many modes a fiber can support, It is given by, where d is the diameter of the core, l is If V ≤ 2.405, then the fibre is single mode fibre (SMF) If V > 2.405, then the fibre is multimode fibre (MMF) Number of Modes traveling in Fibre. The total number of mode traveling in a fibre depends on the V - Number and is related as: For Step Index Fibre: For Graded. When the core diameter is small, only a single mode is permitted and the fiber is said to be a single-mode fiber. Fibers with large core diameters are multimode fibers. One of the difficulties associated with light propagation in multimode fibers arises from the differences among the group velocities of the modes. This results in a variety of travel times so that light pulses are broadened as. As you know, there are two main types of optical fiber: single-mode and multimode. Both types of fiber are composed of only two basic concentric glass structures: the core, which carries the light signals, and the cladding, which traps the light in the core (Fig. 1). Single-mode fiber has a smaller core -- only 9 microns in diameter - and only 6 times the wavelength of light it transmits. The.

For the tighter geometric characteristics and optimised-optical specifications, the fibre is good performance in pigtails use. It.
The optical fiber has almost the same size as existing standard single-mode optical fibers and has the same coating diameter, therefore it can be easily cabled and installed using existing equipment. Furthermore, the transmission capacity has been demonstrated to exceed record transmission in conventional fibers by a factor of 8. Such a fiber maybe be suitable for transmission scenarios where. Depressed inner cladding single-mode fiber A depressed inner cladding single-mode fiber has: - absolute index differences: ∆n+ = 4.10-3 and ∆n- = 2.10 ; - a core diameter: 7 µm; - an inner cladding diameter: 50 µm; - an outer cladding diameter: 125 µm. 1) Calculate its cut-off wavelength.

Multi-mode fibers are described by their core and cladding diameters. Multi-mode optical fiber-Wikipedia. Traditionally, PMMA (acrylic) comprises the core (96% of the cross section in a fiber 1mm in diameter), and fluorinated polymers are the cladding material. Plastic optical fiber-Wikipedia. The core is surrounded by a medium with a lower index of refraction, typically a cladding of a. The structure consists of a short section of an endlessly single mode Photonic Crystal Fiber (PCF) as sensing element, sandwiched between a lead-in and lead-out SMF28 fiber. Core diameter mismatch obtained by mutual distance of fiber ends leads to guidance of light in the structured cladding of the PCF. This makes the transmission of the device dependent on the refractive index of the external.
The highest spatial channel count reported to date for 125-flm diameter cladding fiber is eight single-mode cores [9,10]. Recently, elliptical-core few-mode fibers (EC-FMF) were introduced as an. The fiber is a smaller core MMF that has a mode field diameter for the fundamental mode compatible with that of standard single-mode fiber. Its single-mode and multimode transmission capabilities were demonstrated using different types of transceivers.

The fiber provides the highest core count and low total-crosstalk less than −20 dB/1000 km in C+L band Sama seperti jenis single mode, jenis ini juga terjadi perubahan index bias dengan segera pada batas antara core dan cladding. Diameter core sebesar 50 - 400 um ini digunakan untuk dapat menaikkan efisiensi coupling pada sumber cahaya yang tidak koheren seperti LED. Jenis kabel ini kurang populer dibandingkan dengan single model fiber
Shop AMX Network Cable Accessories. From the People Who Get IT Two methods to measure the cladding diameter of single-mode fibers are presented. The first method is based on an interference fringe measurement technique. Interference fringe spacing at two different planes is measured to determine the cladding diameter of the fiber. The theory of the fringe formation in the interferometeric arrangement using. Photosensitive Single-Mode Fiber Nufern Cladding Mode Suppressed Photosensitive Fiber is designed for very good cladding mode suppression— cladding modesare suppressed to less than 0.1 dB for a 30 dB grating and low splice loss. This photosensitive fiber provides cost-savings for grating-writing because customers can write highly repeatable, quality gratings in a short time. NU0013-11/06 Typ.
Dimensions of single mode/multimode fiber . In single mode optic fiber cable, core-to-cladding diameter is about 9 microns by 125 microns. In multi mode optic fiber cable, core-to-cladding diameter is about 50 (or 62.5) microns by 125 microns. The figure depicts the fiber optic cable and mentions the core and cladding portions Reduced-cladding single-mode fiber is a kind of bending-insensitive SM fiber with higher NA. The reduced cladding/coating dimension decreases the sensitivity of the fiber to bending losses and allows extremely tight fiber coiling with low bending losses. According to the requirement of the customer, the fibers can be specially designed to obtain variable cut-off wavelength, MFD and bending. SINGLE MODE FIBERS. In general, the single mode fibers are step - index fibers. These types of fibers are made from doped silica. It has a very small core diameter so that it can allow only one mode of propagation and hence called single mode fibers. The cladding diameter must be very large compared to the core diameter. Thus in the case of. Single-Mode Fibre Bend Insensitive G.657.A1- 200um Coating C1013, C1015, C1017, C1211, C1239, C1258 G.657.A1 Bend Insensitive 200um Single-Mode Optical Fibre Specifications Corning® ClearCurve® Ultra Optical Fiber Cladding Diameter 125,0 ± 0,7 µm Cladding Non-Circularity ≤ 0,7% Core/Cladding Concentricity ≤ 0,5 µ For standard telecommunication single-mode fiber (SMF), the core diameter is around 9 microns and the cladding diameter 125 microns. SMF is utilized in long-haul applications with transmission distances up to 100km, without the need for any repeater. Multi-mode fiber (MMF) typically uses a core/cladding diameter of 50 microns/125 microns, which provides less reach - up to approximately 2km.
Practically, core diameters and numerical apertures are larger for multimode fibers than for single mode fibers. Consequently, it may be possible to inject non negligeable ratio of light coming from a reasonably large light source ( as LEDs or other non coherent light source ) in a multimode fiber. However it depends on the fiber and particulary on its numerical aperture and its core diameter. Single-mode optical fiber has a small core diameter through which only one mode will propagate. Single mode fiber provides higher transmission speeds and longer distances compared to multimode fiber, and has a lower numerical aperture due to the much smaller core size. We offer a wide variety of single mode fibers to meet most application needs with the initial beam diameter (2w0) set to the mode-field diameter of the fiber of 10.5 μm. We find that the BeamAlyzer data is unreliable and does not fit the theoretical description. On the other hand, the knife edge scan and the pinhole power measurements show that the Gaussian beam model can be used to accurately and precisely describe the beam divergence to a very high degree. We also. Fiber optic multi mode memiliki diameter core sekitar 50-62,5 mikron (lebih besar dibanding single mode) yang membuat cahaya di dalamnya akan terpantul-pantul di dinding cladding. Hal ini dapat menyebabkan berkurangnya bandwidth dari fiber optic jenis ini. Ukuran core yang besar memungkinkan fiber optic mendukung berbagai mode elektromagnetik untuk frekuensi dan polarisasi tertentu A single-mode fiber is used to carry just one light wave over very long distances. Bundles of single-mode optical fibers are used in long-distance telephone lines and undersea cables. Multimode optical fibers, which have a core diameter of 50 micrometers and a cladding diameter of 125 micrometers, can carry hundreds of separate light wave signals over shorter distances. This type of fiber is. Single-mode fiber-optic cable has also been getting increased attention as local-area networks have been extended to greater distances over corporate campuses. The core diameter for this type of fiber-optic cable is exceedingly small, ranging from 8 microns to 10 microns. The standard cladding diameter is 125 microns. SMF step index fibers are manufactured using the outside vapor deposition.


GRadient INdex (GRIN) System
Challenges in imaging Ca2+ in large numbers of endothelial cells in physiologically-relevant pressurized arteries have limited progress in understanding how pressure-dependent mechanical forces alter networked Ca2+ signalling.
We have developed a miniature wide-field, gradient index (GRIN) optical probe designed to fit inside an intact, pressurized artery. Using this setup, we are able to image Ca2+ signals with subcellular resolution in a large number (~200) of naturally connected endothelial cells at various pressures.
This cartoon shows the GRIN microprobe assembly inside a pressurized artery and endothelium.
The GRIN microprobe consists of a single pitch GRIN relay lens (SRL-050; Nippon Sheet Glass, USA) with dimensions ø = 0.5 mm and length = 30.2 mm.
A 0.5 mm x 0.5 mm x 0.5 mm aluminium-coated micro-prism (66-771; Edmund Optics, USA) is attached to the distal surface using UV-curing optical epoxy (NAO 68; Norland Products, USA). The distal end of the GRIN rod with the prism attached is shown in the high resolution microscope image below.
The lens was sheated in a surgical stainless steel tube (0.71 mm outder diameter) for mechanical protection.
In this single lens configuration, the GRIN rod acts to reconjugate the image plane of detection optics through the length of the cylinder.

Imaging using the GRIN system
A Time series Ca2+ images of endothelial cells showing the progression of the Ca2+ response evoked by ACh (100 μm; bath applied; 1 μm estimated at the vessel lumen) recorded at 60 mmHg. Images are composed of instantaneous Ca2+ activity (green) overlaid on standard deviation images (greyscale) indicative of total Ca2+ activity. Scale bar: 100 μm. B ACh‐evoked Ca2+ signals from the same cells shown in A. In the left panel (unaligned data) the range of times for Ca2+ to increase for each of the ∼200 cells is approximately 4 s. The spread of responses resulted in mean data representing the data poorly. The position of the first peak of derivative signals was used to align Ca2+ signals, synchronizing the Ca2+ rises occurring in each due to the action of ACh (middle panel ‘aligned’) and illustrating total Ca2+ activity (red line). On successive application of ACh (20 min reequilibration following wash), the response to ACh was reproducible. C Select examples of unaligned (left) and aligned (right) cellular Ca2+ responses from ROIs shown in A. The grey box illustrates the time point of measurements from aligned signals. D Summary data illustrating the reproducibility of Ca2+ responses upon repeat application (wash + 20 min reequilibration) with ACh.
Curved image plane correction in the GRIN probe
In uniform optics, field curvature arises from the use of curved optics producing images on a curved plane. This is a problem when imaging as the majority of detectors are flat.
For GRIN optics, which may be very narrow and long, far-field waves travel further than near field ones due to the refractive index changes in the material , causing off-axis rays to be focussed at a different focal plane

Model No.: SMD LED lamp beads 3535
What is "Flip Chip"? How is its structure? What are the advantages?
Blue LEDs usually use Al2O3 substrates. Al2O3 substrates have high hardness, low thermal conductivity and low electrical conductivity. If the front-mounted structure is adopted, on the one hand, it will bring about anti-static problems, on the other hand, heat dissipation will also become a problem under high current conditions SMD lights with LED. The main problem. At the same time, since the front electrode faces upward, a part of the light will be blocked, and the luminous efficiency will be reduced. High-power blue LEDs can obtain more effective light emission through chip flip-chip technology than traditional packaging technology Light Emitting Diode SMD.
The current mainstream flip-chip structure method is: first prepare a large-size blue LED chip with suitable eutectic welding electrodes, and at the same time prepare a silicon substrate slightly larger than the blue LED chip, and fabricate gold for eutectic welding. Conductive layer and lead wire layer (ultrasonic gold wire ball solder joints). Then, the high-power blue LED chip and the silicon substrate are welded together using eutectic Welding equipment. The feature of this structure is that the epitaxial layer is directly in contact with the silicon substrate, and the thermal resistance of the silicon substrate is much lower than that of the sapphire substrate, so the heat dissipation problem is well solved. Since the sapphire substrate faces up after flipping, it becomes the light emitting surface, and the sapphire is transparent, so the light emitting problem is also solved SMD LED lights.

Aims: With advances in CMOS sensor technology, optical mapping measurements can be performed at megapixels resolutions >1 Mpixel and frame rates >500 fps at staggering data rates >1 GB/s, two orders of magnitude than a decade ago utilizing CCD sensors. Removal of baseline wandering involves non-linear methods of >O(n^2) complexity and this study aims to present a GPU accelerated parallel image processing method suitable for near real-time removal of optical mapping baseline wandering.
Methods: Optical mappings were performed on isolated rabbit hearts with Di-4-ANBDQPQ Vm dye at resolution of 1600x1000 pixels at 500 fps. Baseline wandering removal was assessed with Keiser Window and Equiripple finite impulse response (FIR) filters in MATLAB with CPU processing (Intel i7, 8th generation) and GPU processing (NVIDIA 1080Ti 3584 CUDA cores), and native CUDA GPU processing, all in dual precision. Filter parameters are assessed with different slopes between stop band frequency (Fs) and pass band frequency (Fp), with Fs/Fp ratios ranging from 0.1 to 0.9.
Results: FIR filters processing time was timed for different Fs/Fp ratios exhibiting exponential complexity as the ratio approaches to 1. GPU acceleration in MATLAB resulted in processing speed increase of up to 10 times, while native CUDA GPU processing resulted in speed increase of up to 50 times compared to single core CPU processing. CUDA processing data flow rates ranged from 2.5 GB/s for Fs/Fp = 0.1 down to 300 MB/s for Fs/Fp = 0.9.
Conclusions: GPU gaming class cards nowadays have few thousands cores at affordable prices and are suitable tool to leverage technological progress in optical sensors developments with increased resolution/frames rates as image processing is suitable for parallelization. Near-real time processing capabilities allow optical mapping method to become the research tool for real-time experimental setups enabling on-site decision making process, and disrupting traditional off-line data analysis.


Image Stabilizer lenses and autofocus
When shooting with an image stabilized lens, especially a long telephoto, if you don’t need to use the IS because your shutter speed is fast enough to avoid camera shake, try turning it off for even faster autofocus. This is especially useful for fast moving subjects where absolute AF speed is important. I mainly use the stabilizer when shooting speakers or subjects in low light when I feel the ISO starts to lose sharpness, which is around 1600 ISO for a Canon 2o MP full frame DSLR camera.

Never been done before, a new transparent solar cell was recently developed by researchers at a Silicon Valley startup named Ubiquitous Energy. This innovative technology could greatly expand the capabilities of solar power and allow more practical ways of generating power in homes and even skyscrapers.
The invisible film can be applied to any surface and generate power which may lead to smartphones and tablets that can last forever without charging. Once thought impossible due to its transparent nature, the design uses photo-active materials which allow visible light to pass through while harvesting non-visible wavelengths of UV and infrared light.
With traditional photo-voltaic solar cells, 33% of the energy from light is converted to energy while transparent solar cells can only harvest 22%. Despite the lower percentage, the wider-range of versatility will allow these cells to produce energy in places which were never possible before. You can learn about these transparent solar cells in the video posted below.

Understanding the theory of LESS
The aim of LESS is to simulate the radiation interactions within intricate landscapes, such as forests and urban structures. The following two figures succinctly outline the primary functionalities of LESS. By inputting landscape structural data, component spectra, illumination/observation geometries, and other necessary information, LESS utilizes ray tracing techniques to solve the 3D radiative transfer problem. It then generates remotely sensed signals, encompassing canopy reflectance, LiDAR data, multispectral images, Solar-Induced Fluorescence (SIF), as well as various process parameters like Fraction of Photosynthetically Active Radiation (FPAR) and photosynthesis rates.
This process is often referred to as “forward simulation or modeling”. Unlike other 1D models, LESS does not rely on assumptions that abstract the canopy as homogeneous layers. Instead, it employs explicitly described structures to represent landscape elements, even down to the detailed structures of individual leaves or shoots. Consequently, LESS is renowned for its precision. Since the ray tracing technique utilized by LESS simulates light scattering at each ray-object intersection point based on fundamental physical laws (e.g., Lambertian reflection), simulations conducted by models like LESS are sometimes termed “first principle” simulations.
In summary, LESS yields considerably accurate results for light scattering within complex landscapes, facilitating various applications such as forest parameter retrieval, comprehension of remote sensing mechanisms, and sensor instrument design.
Light scattering within a forest canopy:
The diagram of LESS’s functionality:
Why LESS is useful ?
LESS facilitates the aforementioned applications by providing remote sensing observations alongside corresponding “ground truth” measurements. For instance, consider the retrieval of vegetation parameters from canopy reflectance, a fundamental goal in forest remote sensing. To establish a retrieval model, it is imperative to understand the relationship between reflectance and vegetation parameters. While field measurements can offer such insights, they are often laborious and site-specific. Alternatively, employing 3D simulations with LESS serves as an economical alternative. By utilizing the simulated reflectance alongside the ground truth parameters provided by LESS (refer to the figure below), we can establish a regression model or machine learning algorithm. Subsequently, real remote sensing reflectance can be inputted into this model to estimate vegetation parameters. Finally, field measurements can be utilized to validate the accuracy of the model.

Exploring the Wonders of Light: Reflection, Refraction, and Propagation
In the vast realm of physics, few phenomena captivate our imagination like the behavior of light. From the rectilinear propagation of light to the intricate reflections at plane mirrors, the study of light opens a door to a world of wonders.
One of the fundamental properties of light is its rectilinear propagation, which asserts that light travels in a straight line. This property finds evidence in various everyday occurrences, such as the formation of shadows. Shadows, those intriguing silhouettes that appear when light is blocked by an opaque object, come in two types: umbra and penumbra. Understanding the factors that determine the type of shadow formed, such as the size of the light source, the size of the object, and the distance between the object and the light source, allows us to unravel the mysteries of shadows.
Eclipses, those rare astronomical events that captivate the world, are also a result of the rectilinear propagation of light. A solar eclipse occurs when the moon casts its shadow on the earth, while a lunar eclipse happens when the earth’s shadow falls on the moon. These celestial events offer a captivating display of the interplay between light and shadow, reminding us of the beauty and precision of nature.
The pinhole camera, a simple yet powerful device, showcases the rectilinear propagation of light in a unique way. By allowing only a tiny hole for light to enter, it forms images that are diminished, real, and inverted. Understanding the factors that affect the image formed, such as the object distance, image distance, and size of the pinhole, unlocks the secrets of this remarkable camera.
Reflection from plane surfaces takes us into the realm of mirrors. The laws of reflection dictate that the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal lie in the same plane. This knowledge allows us to understand the characteristics of images formed by plane mirrors: they are the same size as the object, virtual, formed behind the mirror, erect, and laterally inverted. Comparing these characteristics to those of the pinhole camera’s images reveals intriguing differences, highlighting the versatility and uniqueness of light manipulation.
As we journey through the study of light, we also encounter the fascinating concepts of refraction, magnetism, sound, waves, and various other phenomena that enrich our understanding of the world around us. Each topic unravels new layers of knowledge, inviting us to explore the intricate dance between light and matter.
In conclusion, the study of light is a captivating adventure that leads us to unveil the mysteries of reflection, refraction, and propagation. From the formation of shadows to the enchanting images created by the pinhole camera, we witness the beauty and complexity of light’s behavior. So, join us on this enlightening journey as we delve into the wonders of light and its impact on our world.
Theme: The theme of this essay revolves around the exploration of light and its various phenomena, such as reflection, refraction, and propagation. It highlights the captivating nature of light and its interaction with matter, inviting readers to delve into the intricate world of physics.


Eye Surgery has actually come to be a mainstream approach of vision adjustment, and this post will certainly clarify the advantages and disadvantages of three various approaches being offered to the clinical consumer.
Lasik Eye Surgical treatment
LASIK is the acronym for Laser-Assisted In Situ Keratomileusis and is an eye surgical system which completely fixes vision by removing a thin layer of the cornea. This treatment functions best on patients with moderate to high degrees of myopia (nearsightedness), reduced to moderate levels of hyperopia (farsightedness) and also astigmatism connected with nearsightedness, and who have thick corneas. It is the most popular medical vision improvement method.
People with typical eye sight see items plainly due to the fact that images are brought right into a proper prime focus by the cornea and also lens of the eye. Ideally, the cornea's curvature is evenly matched to its size in a typical eye. People with astigmatism, nearsightedness or hyperopia have off-and-on formed corneas, so the things seen are not focused effectively. LASIK changes corneal shape by exact removal of corneal cells, as well as by doing so corrects the eyes' concentrating power.
There are, however, dangers to LASIK eye surgical treatment.
There is a remote opportunity of complete loss of vision. If this happens, it is normally due to the fact that the patient had a pre-existing condition which needs to have precluded the surgical treatment to begin with, such as maternity, cataracts, joint inflammation, diabetes mellitus, glaucoma, or lupus. People with big pupils are likewise bad prospects for LASIK. Dry eye disorder will certainly be intensified by this procedure.
A couple of people grumble that they permanently see "ghost" pictures, have actually blurred vision, reduced comparison as well as poor night vision. When LASIK wased initially presented, 5% of individuals had post-operative grievances; however, improvements in the treatment have created this rate to drop to less compared to 1% if LASIK is done by skilled practitioners and patients are properly screened prior to surgical procedure. If issues do occur, they could usually be resoved by a retreatment.
FDA has actually accepted LASIK laser eye surgical procedure given that 1998. While there are a lot of completely satisfied people, there are however no long term research studies about its results. Realize the limitations as well as the risks of LASIK eye surgery prior to you sigh up for the procedure.
Though much less popular, these little implants can enhance vision in patients with moderate to modest myopia without the danger of long-term eye damage fundamental in the tissue elimination technique of LASIK. Intacs are semi-circular disks dental implanted in the cornea which extend it to presume a flatter shape. Though slightly less accurate compared to LASIK, they are removeable and changeable, so if the client has an unexpected over- or under-correction, the implant can be eliminated and another of a various dimension inserted to get the wanted modification. The implants lie at the edge of the cornea, so the central aesthetic location is entirely undamaged and undamaged, and also the toughness of the cornea is undiminished, making it a better alternative for pilots as well as those that participate in contact sports where eye injury is a possibility.
Intacs disagree for serious myopia and also more than minor astigmatism (1.00 diopters), as the cornea could just be extended so far. If the Intacs are eliminated, vision see go back to its preoperative degree. Apart from vision modification, Intacs are likewise used to treat keratoconus.
Intacs are FDA accepted as well go to this site as 10 year researches have revealed no significant troubles with Intacs as well as few person issues; however, because the procedure takes a lot more training compared to LASIK, there are fewer eye surgery clinics offering it. Nevertheless, the Intacs website provides a checklist of professionals in each state, also a couple of in Canada, Europe and also Mexico.
Since many people do not want to take the chance of LASIK and Intacs could not help those with serious vision troubles, intraocular lens implants (IOL) are a new choice approved by the FDA in 2004 to deal with modest to serious nearsightedness. The Artisan lens, produced by Ophtec, is similar to the sort of lens implant used to bring back vision following cataract eye surgical procedure.
The brand-new IOL, called the Craftsmen, is intended for only individuals who have 2.5 diopters or much less of astigmatism.
The artificial lens does not change the natural lens, however is placed before it. The major trouble found with the implant was the steady loss of endothelial cells in the corneas of clients that received the implants. The endothelium is a layer of cells that line the undersurface of the cornea and are important in keeping the cornea clear. A three-year study showed a consistent constant loss of endothelial cells of 1.8 percent a year. Now, no person can forecast whether this loss will certainly proceed at the exact same rate indefinitely, or even its influence on corneal function.
To lessen long-term results of the tool on the corneal endothelium, the FDA is calling for that the brand-new lenses be identified to define that they need to only be implanted in individuals whose corneal endothelial cells are thick adequate to endure minor cell loss.
A lot more serious issues were few: retinal detachment (0.6%), cataract advancement (0.6%), and corneal swelling (0.4%). The FDA is needing Ophtec to perform a five-year follow-up survey of its dental implant people to much better evaluate the post-surgical incidence of cataract advancement, retinal detachment and also other sensory conditions.
The Artisan lens is intended to be a long-term implant.Though it can be eliminated surgically, vision may not constantly go back to just what it was prior to getting the lens. Since it does not influence astigmatism, individuals with this trouble could still call for glasses.


The earth absorbs UV and visible light from the sun. Due to the earth having a lower temperature than the sun, the earth emits a longer wavelength of light: infrared. The infrared light leaves earth, but can sometimes be absorbed and re-emitted by greenhouse gases, such as carbon dioxide or methane. These molecules can re-emit the infrared radiation in any direction, and so some of the infrared light ends up directed back toward earth. This means there is an increase in the total incident light on earth: the UV and visible light from the sun, and the infrared reflected back to earth by greenhouse gases.
Hope this helps! :)


Two Concerns Individuals Do Not Really Know Regarding To LASIK Eye Medical SurgeryThe eye can be analyzed with relative ease as to both its function and its structure. A functional assessment consists of the ability to move in the orbit and the reaction of the student to light and lodging.
The function of the eye may be tested in numerous ways. The client might be asked to determine illuminated letter or items of varying sizes on what is known as the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in a number of methods. Stress within the eyeball is determined by a "tonometer." In certain diseases, specifically in glaucoma, the stress in the eyeball is increased significantly.
Nevertheless, it needs to be well bore in mind that a client with an eye issue might have other problems too. Frequently other physical conditions are primary and affect the eye as a consequence. The look of the eye can notify the doctor and the client to problems in some disruptions of other parts of the body even before other signs present themselves.
One's reliance on sight is emphasized when one deals with a possible or temporary long-term loss of this crucial sense. When restorative measures are sought, certain types of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to encourage reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this type of surgical treatment, one's vision is corrected permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The main purpose of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea utilizing a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgery, there are still disadvantages that people must know. Most likely, the primary reason that this type of eye surgical treatment has become well accepted is because the majority of its cases had actually succeeded.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most sensitive part of the eye
Due to the fact that LASIK eye surgical treatment involves the operation of the retina, which is one of the most sensitive parts of the eye, the majority of people say that the operation can be very dangerous.
To puts it simply, a easy error could nearly cause an person's life time loss of sight. It is important to consider numerous aspects before choosing whether LASIK eye surgery is the ideal restorative measure one has to go through.
2. It is not a best procedure
LASIK eye surgical treatment might fix your vision but it does not always imply that it can provide you a twenty-twenty. Even if analytical reports show that 70% of the patients might have 20/20 vision, this does not necessarily indicate they have perfect vision too.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the ideal eye surgical treatment the method many people view it
On the other hand, the assessment of the structural part of the eye might be made in numerous methods. It ought to be well kept in mind that a client with an eye problem may have other issues. Frequently other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can inform the client and the physician to troubles in some disturbances of other parts of the body even before other signs provide themselves.
Like its tangible counterpart, LASIK eye surgical treatment my sources is another type of vision correction.


Subsea 7 and 3D at Depth have completed several metrology projects using subsea LiDAR technology developed by 3D at Depth.
Subsea 7’s project stationed two 3D at Depth SL1 systems independently to collect simultaneous metrologies utilizing separate ROVs.
The survey conducted in the Mississippi Basin, Gulf of Mexico, completed a total of six spool metrologies.
The ranges achieved by 3D at Depth’s sensor technology allowed for a single set up and scan over a 220°-degree arc.
Derek Perce, 3D at Depth Subsea LiDAR Specialist said: “3D at Depth will continue to provide our customers with innovations to LiDAR technology that demonstrate performance and increase the efficiencies of data collection, mapping and visualization.“


Two Considerations You Do Certainly Not Recognize About LASIK Eye TreatmentsThe eye can be examined with relative ease regarding both its function and its structure. A functional assessment consists of the capability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye might be checked in several ways. The patient may be asked to recognize illuminated letter or items of varying sizes on exactly what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In particular illness, particularly in glaucoma, the tension in the eyeball is increased noticeably.
Nevertheless, it must be well bore in mind that a patient with an eye issue might have other issues as well. Often other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can signal the patient and the physician to problems in some disturbances of other parts of the body even before other symptoms present themselves.
One's dependence on sight is highlighted when one faces a possible or short-term irreversible loss of this crucial sense. For this reason, when restorative steps are sought, certain types of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are troubled with the fact that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were developed to encourage reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.

Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people need to understand. Probably, the main reason this kind of eye surgical treatment has actually become well accepted is due to the fact that the majority of its cases had actually been effective.
In spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Due to the fact that LASIK eye surgical treatment involves the operation of the retina, which is one of the most sensitive parts of the eye, many people state that Recommended Site the operation can be really risky.
To puts it simply, a simple error could nearly cause an individual's lifetime blindness. Thus, it is crucial to think about many factors before choosing whether LASIK eye surgical treatment is the right restorative measure one has to undergo.
2. It is not a ideal procedure
LASIK eye surgical treatment might fix your vision but it does not always indicate that it can provide you a ideal vision. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not always suggest they have ideal vision also.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgical treatment the method the majority of people see it
Conversely, the examination of the structural part of the eye might be made in a number of ways. It ought to be well remembered that a client with an eye problem might have other issues. Frequently other physical conditions are main and impact the eye as a effect. The look of the eye can alert the physician and the patient to problems in some disturbances of other parts of the body even prior to other signs provide themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction.


Types of Microscopy
Four types of microscopy are used in materialographic testing, depending on the nature of the workpiece and the object of investigation, and they are described below.
In optical microscopy different filters are used to improve contrast and emphasize specific features based on material properties. This can be achieved with magnifications typically ranging from 2.5 times up to 1,000 times. In materialography, reflected light is the most commonly used type of light optical microscopy. Transmitted optical microscopy is also used, but mainly for mineralogy specimens.
Stereo Optical Microscopy
The stereo microscope is an optical microscope variant, designed for low magnification observation of a specimen, using the light reflected from the specimen surface.
Scanning Electron Microscopy
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a specimen by scanning the specimen surface with a focused beam of electrons. The electrons interact with the atoms in the specimen, producing various signals that can be translated into information about the surface topography and the composition of the specimen.
Transmission Electron Microscopy
Transmission electron microscopy (TEM) uses a beam of electrons transmitted through an ultra-thin specimen and that interacts with the specimen as it passes through it. Generated signals can be translated into various types of information, including information on the type and orientation of individual crystals.


What is Lenticular?
Lenticular 3D graphics is the process whereby you add dimension and/or motion to your printed marketing displays. "Lenticular" means "pertaining to lenses," and "lenticules" are the plastic lenses that create the illusion of dimension in depth imaging. Placing special lenses, or "lenticules," over a two dimensional print allows the eye to simultaneously view alternating sections of multiple images. (See below: How it Works)
Lenticular 3D images do not require any special equipment to view, and are adaptable to many types of installations and uses. You can utilise Lenticular imaging for any project imaginable: Direct Mailers, Packaging (hang tags, labels, package wraps as well as 100% Lenticular containers and cartons), In-Store Retail Graphics, POS, Posters, Murals -- any time you need people to stop and take notice!
How It Works
Lenticular graphics are made up of two components: a lenticular lens, and a flat printed image. The lens is a sheet of material that feels like grooved plastic. The grooves and ridges are actually lenticules which focus your sight on different parts of the underlying picture. The printed picture is actually made up of multiple pictures which are printed in alternating lines. A narrow band of each image will be printed sequentially with narrow bands of each additional image. The effect is actualized when mounted to a sheet of lenticular lens specially chosen for the desired effect.
There are two categories of effects that can be achieved with Lenticular imaging: 2D (Flip) and 3D. Additionally, you can combine both Flip and 3D effects.2D (Flip) images
If two images will be combined (called a 2D (Flip), the composite print will include a narrow band of image #A, followed by a narrow band of image #B. That pattern of printing is continued (A-B-A-B-A-B) for the entire composite print. This process is called "interlacing." When viewed under the lenticular lens, a different view of the image is received depending on your viewing angle. This creates the special effect. Different lens patterns and materials are used depending on the size of the printed piece and the viewing distance required. This simple yet visually stunning 2D (Flip) effect is illustrated below in a job we did for a major client:
3D Depth images are a little more complicated. Parallax is the bio-physical phenomenon that allows us to perceive the world in three dimensions. Normally, parallax is produced by the separate viewing angles of our eyes. Our brain compares the different views, from right and left eyes, processes the data, and creates what we see as a three-dimensional world. Think of stereoscopic viewing. Remember looking through a ViewMaster®? Each eye would see a different slide. Each slide would be a different viewing perspective of the same subject matter, and via parallax your brain would perceive the composite image as having depth.
Using the same technique described for flip effects, vastly superior 3D Depth effects can be achieved by imaging alternating strips of the same image viewed from different angles. When an image interlaced for 3D is placed under a lenticular lens, we invoke the parallax phenomenon to trick the brain intoseeing depth and volume in a two-dimensional image. Please note that this unique technique does not require any sort of 3D glasses to be worn to achieve the effect.
Basic "Flip" effects are the most common effects that can be produced by Lenticular graphics. A "flip" or "view" refers to each image that is interlaced into a Lenticular graphic. A "Two Flip" forms the foundation of flip effects, and results in two images "flipping" back and forth as the viewing angle of the printed piece is changed. Two-flips are the most dramatic of the flip effects, and are fantastic for demonstrating Before-and-After, Old-versus-New comparisons, etc.
More than two images can be interlaced together to produce "Multi Flip" Images. In addition to two-flip image transitions, you can employ three or more image transitions. Special effects like "Zoom" and "Animation" can be achieved utilizing the multi-flip technique.
Animation & High Definition Lenticular
Animation effects mimic the smooth movement of video. HD Lenticular(R) from Big3D provides the highest image resolution available anywhere -- imagine reproducing 5-15 seconds of High Definition footage in a Lenticular postcard -- its like video in your hand!
Zooms and morphs are special multi-flip effects that look just like they sound. Zooms give the illusion of all or a portion of an image moving forward and backward, and Morphs are the conversion of one image into another.
3D Lenticular is truly a spectacular and unique application of lenticular graphics. The illusion of depth is so convincing that the viewer is captivated by the realism! To create a 3D image, all the elements in the 3D "scene" are placed in separate layers. Special digital processing is employed to create depth and volume to those layers. When the processed image is viewed through the Lenticular lens, the 3D depth is perceived -- all with the naked eye!
The most complex of all Lenticular effects: Flip effects with 3D! Imagine images zooming and or flipping, all with 3D depth!

This reticle enables shooters to compensate for the amount a bullet drops over a particular distance. Markings below the reticle’s center indicate the expected impact point at a given distance, with lower markings showing the expected impact point at longer distances. The amount of bullet drop at a given distance depends on the type of firearm and ammunition being used. The following guidelines indicate the approximate bullet drop for a center fire hunting rifle such as a .30-06 or 270 at the highest power. However, testing at a range is needed to more precisely determine how much bullet drop to expect at a given distance for a particular firearm. The BDC reticle markings assume that the rifle has been sighted in at 100 yards on the highest power. Therefore, bullet drop at 100 yards, indicated by the reticle’s center, would be zero. Provides accurate holdovers for 200, 300, 350, 400, 450 and 500 yards out. @ maximum magnification.

Indicates whether the image should be changed, without distortion, so that it fits the bounds of the image control.
Set Proportional to true to ensure that the image can be fully displayed in the image control without any distortion such as occurs with the Stretch property. When Proportional is true, images that are too large to fit in the image control are scaled down (while maintaining the same aspect ratio) until they fit in the image control. Images that are too small are displayed normally. That is, Proportional can reduce the magnification of the image, but does not increase it.
When the image control resizes, the image resizes also.
To resize the image so that it fits exactly in the image control, even if that causes distortion, use the Stretch property instead.
To resize the control to the image rather than resizing the image to the control, use the AutoSize property instead.
The default value for Proportional is false.
Note: Proportional has no effect if the Picture property contains an icon.

Laser cutting is a precision cutting method widely used in industrial manufacturing. Laser cutting allows a level of accuracy unmatched by any other cutting method. A high-powered laser is directed at the material to be cut. The material burns, melts or vaporizes, leaving a high quality finish.
Apart from the common materials such as wood, plastic and metal, laser cutting is also widely used in the processing of glass. Glass has become sheets of plywood an important component of a large number of applications. Its use is not just restricted to windows and bottles but has expanded to telecommunications and information technology. These modern applications require a higher level of accuracy and precision that cannot be matched by traditional methods.
Traditional glass cutting methods make direct contact with the surface, increasing chances of unwanted scratches and abrasions. Moreover, material losses and glass dust are other problems faced in the conventional process.
The use of lasers has revolutionized the art of glass cutting. The laser beam is used to produce highly complex and accurate shapes with a fine edge finish. The power of the laser beam ranges between 1000 to 2000 watts. Most laser cutters are integrated into an enclosed machine with state-of-the-art software. Since the laser used is a “class 4” laser, care is taken to keep the user away from direct contact. The CO2 laser is the most common device used in glass cutting.
The advantages of laser cut glass are many. Apart from the superb quality edges, flaking, chipping and micro-cracks are almost completely eliminated. Moreover, laser cut glass is up to 3 times more durable than conventional cut glass. Since cutting oil is not used in the process, the glass washing process is also minimized.
Laser glass cutters can be used to cut glass of any thickness with an equal amount of accuracy. From decorative articles and frames to quartz crystal oscillators and display glasses, the use of these devices is limitless.


This text describes the technique of optical spectroscopy applied to problems in condensed matter physics. It relates theoretical understanding to experimental measurement, including discussion of the optical spectroscopy of inorganic insulators, with many illustrative examples. Symmetry arguments are developed from a formal group theoretical basis and are frequently used, and a special effort is made to treat the subject of lattice vibrations and to show how these can affect the spectroscopic properties of solids. The elements of laser theory are developed, and the authors also explore the use of optically detected magnetic resonance techniques for the investigation of semiconducting materials.This text describes the technique of optical spectroscopy applied to problems in condensed matter physics.
