Fluorescence spectroscopy (also known as fluorometry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. Fluorescence is a photon emission process that occurs upon molecular relaxation from an electronically excited state to an electronic ground state. Fluorescence spectroscopy is widely used in Biochemical research.
INTRINSIC PROTEIN FLUORESCENCE
- The amino acid tryptophan has the strongest fluorescence quantum yield of the amino acids found in proteins. The rest either do not fluoresce or fluoresce weakly. Therefore “Intrinsic Protein Fluorescence” usually refers to the fluorescence emission of the tryptophan amino acids.
- In a hydrophobic environment (buried within the core of the protein), Tyr and Trp have a high quantum yield and therefore a high fluorescence intensity. In contrast in a hydrophilic environment (exposed to solvent) their quantum yield decreases leading to low fluorescence intensity.
- For Trp residue, there is strong stoke shifts dependent on the solvent, meaning that the maximum emission wavelength of Trp will differ depending on the Trp environment.
- High resolution (1.0 nm)
- High scan speed up to 24,000 nm/min
- Sensitivity, high performance R928 PMT detector combined with PerkinElmer optics ensures optimum performance across the spectrum.
- Broad excitation and emission wavelength range up to 900 nm
- For samples at risk for photo-bleaching the FL 6500 provides accurate and high quality results with a user controllable pulsed excitation source.
- Superior wavelength accuracy and reproducibility for right first time results

Matt coating interpretation as well as significance
How does a gloss meter work?
The dimension results of a glossmeter are related to the amount of reflected light from a black glass criterion with a specified refractive index. The ratio of shown to case light for the specimen, compared gloss meter to the ratio for the gloss standard, is videotaped as gloss systems (GU). The device of dimension utilized by a gloss meter is called a gloss system (GU).
The dimension range, Gloss Devices (GU), of a glossmeter is a scaling based on a very polished recommendation black glass standard with a specified refractive index having a specular reflectance of 100GU at the defined angle. This standard is utilized to establish a top point calibration of 100 with the reduced end factor established at 0 on a perfectly matt surface area. This scaling appropriates for a lot of non-metallic finishings as well as materials (paints as well as plastics) as they generally drop within this array. For various other products, highly reflective in appearance (mirrors, layered/ raw steel elements), greater values can be achieved reaching 2000 Gloss Systems.
- This scaling is suitable for the majority of non-metallic coverings and materials (paints and also plastics) as they normally drop within this range.
- The measurement range, Gloss Units (GU), of a glossmeter is a scaling based on a highly refined referral black glass requirement with a defined refractive index having a specular reflectance of 100GU at the defined angle.
- This criterion is used to establish a top point calibration of 100 with the lower end point established at 0 on a completely matt surface area.
For transparent materials, these values can likewise be raised because of several reflections within the product. The glossmeter provides a quantifiable way of determining gloss strength ensuring uniformity of dimension by specifying the exact lighting and also watching conditions. The arrangement of both illumination source as well as observation function angles permits measurement over a tiny series of the overall representation angle.
PCE Instruments markets a range of gloss measuring tools that cover the gloss determining range from matte to mirror gloss. PCE Instruments’ diverse gloss meter items have different determining varieties to fit gloss dimensions of varnishes and paints along with sleek metals, mirrors and likewise glossy surfaces. As an example, for identifying the gloss of paints and also varnishes, generally, a measuring range from 0 to 100 gloss units is sufficient.
The PCE-GM 60Plus gloss meter is a portable handheld 60 degree gloss meter. This finish and also paint gloss meter determines the gloss devices (GU) on a material’s surface. The rechargeable gloss meter or gloss tester utilizes reflected light for gloss measurement per ISO 2813, GB/T 9754, ASTM D523 and ASTM D2457 requirements. A gloss meter procedures gloss devices of repainted, covered as well as shiny surfaces normally from 20-degree, 60-degree and 85-degree reflective angles. When selecting the proper angle for gloss dimension, it is essential to think about the gloss series of the surface area.

Laser marking machines are used everywhere from mechanical engineering to souvenir production. The demand for laser metal engravers is growing due to the large-scale use of equipment for engraving products.
In this article, we will tell you what a laser marking machine is, what functions it has, and how to choose the most optimal one.
What is a laser marking machine and where can it be used?
A fiber laser marker equipment designed for marking and engraving on material.
The main part of a laser metal engraver is the emitter, which burns out the surface layer of the material with a laser beam.
The laser marking machine can be used to work with the following materials:
- rubber and many others.
The machine is capable of engraving on both organic materials (CO2 systems) and metals (fiber optic markers).
A laser metal marking machine is used to produce:
- license plates;
- souvenir items with engraving and much more.
The laser marker works by burning the pattern on the material, while the possibility of damaging it is excluded.
Advantages of a laser marking machine
- No production waste. Unlike fiber metal cutters, no debris (chips and dust) is generated during the work;
- Easy operation and maintenance. Anyone can master the skills of using the equipment;
- Reliability. When used properly, the purchased equipment will last for many years;
- Wide range of processing materials. The fiber laser marker can work with virtually any material, even the most fragile one. The main thing is to choose the optimal type of equipment;
- Manufacture of high quality products. The laser marker allows you to engrave complex patterns that will be durable and will not change under any circumstances.
The fiber metal laser marker is suitable for the production of any scale. The high-quality equipment pays off quickly and virtually does not need to be repaired during the entire service life (more than 6 years).
Marking and engraving
There are two main types of work done with a fiber laser marker:
In the first case, the material is processed by a machine to apply the desired shade.
When engraving, the material is affected in depth. In other words, a drawing or an inscription is applied by burning the surface.
A single laser marking system can be used for both marking and engraving metal.
A laser marking specifications
The marking laser consists of a large number of elements that ensure its operation. The main part is the emitter.
Emitters are usually divided into two types:
- Fiber optic (ytterbium), designed to work with metal;
- CO2 (carbon dioxide) emitter is used for processing organic material.
The choice of marker always depends on the type of material being processed.
It is worth noting that fiber equipment, unlike gas equipment, has a higher processing speed and a longer service life.
Let us take a look at three proven companies that produce high-quality fiber optic emitters.
Leading manufacturer of components for marking laser equipment.
Due to the high frequency range, machines with this emitter are able to apply color images to hard metals. High performance and protection against reflections makes it possible to process non-ferrous metals.
- Large functionality for a wide range of works;
- Long service life (up to 100000 hours);
- High beam quality without dissipation;
- Unique systems and methods of material processing.
Markers with an IPG emitter are the best choice for high speed processing of complex materials.
A low-cost Chinese brand for the production of marking lasers components.
Max Photonics can be used to produce shields, souvenir products with simple drawings, inscriptions or customer logos, to apply barcodes and serial numbers.
The main advantage of the brand is value for money. Despite the lesser demand, the emitters have a long service life and a wide range of optional features. Lasers with this emitter will allow the owner to process many types of material. Such as:
- epoxy resin;
- ceramics and other.
Markers with an emitter of this brand will be excellent equipment to start your own production.
A Chinese company that has been producing fiber-optic emitters since 2007.
The emitters are mainly designed for marking metal surfaces. High speed, productivity and reasonable cost allow you to perform work both in large and small production.
Criteria for choosing a laser marking machine
Purchasing equipment for production is confusing for inexperienced people. The range is very large, but the choice is always individual. That is why we offer you to note the important criteria for choosing machines (according to technical characteristics). The information will help you to choose the most optimal model for your production.
Engraving detail and material processing speed depend on the choice of emitter power. Accordingly, the higher the power, the faster and better the work of marking laser will be performed.
This criterion is very important if the production is aimed at processing items in large quantities.
Typically, emitters with an average power (20-50 W) are used in production.
When working with fiber laser marker reflective metals (gold, silver and others), you should choose emitters with a power of 70 W or more. However, with such power, it is difficult to polish or clean items.
Lenses and working area
The choice of lens also determines the performance and quality of machining. The lens and the size of the working area are usually chosen in accordance with the thickness, dimensions and texture of the material.
Lenses with a short focal length (up to 2 inches) are used in markers designed for engraving thin material. For materials with greater thickness, long focal length lenses (from 4 inches) are usually used.
The working area is selected depending on the size of the processed item. Among the sizes of the working area, the following are in high demand: 100 * 100, 200 * 200 and 300 * 300 mm.
The controller is a board that is responsible for controlling the operation of the marker.
Wattsan fiber laser marking systems are equipped with their own controllers that interact with the EZ CAD program. The software has extensive functionality for the full-fledged operation of laser markers and built-in generators for barcoding.
When choosing a controller, pay attention to the functionality of the software that is compatible with it.
Another important tool that fiber laser marking systems are equipped with. The scanner directs the laser beam with the help of two rotating mirrors into a special lens. From the lens, the beam is projected onto the material.
The weight of the mirrors determines how high the speed of movement of the laser beam will be. The lower the weight, the higher the speed.

Microscope Glass Slides are mechanical devices used for seeing items and materials so minute in size that they are undetectable by the naked eye. The procedure carried out with such an instrument, called Microscopy, utilizes the combined schools of optical science and light reflection, controlled and controlled through lenses, to study small items at close range.
The fundamental microscope includes numerous complex and interrelated parts: a cylinder that offers a necessary area of air in between the ocular lens (eye piece) located at the leading and the unbiased lens repaired at the bottom, hovering near to a phase consisting of an optical assembly on a turning arm and a centered hole through which a light shines from a solid U-shaped stand below. Amplifying values for the ocular variety through X5, X10, to X20, while the worths for the unbiased lens has a wider period: X5, X10, X20, X80, x40, and x100. These worths supply the observer with a spectrum of possible range orientations and degrees of sharpness as are essential for seeing and analysis.
Numerous different kinds of microscopic lens exist, each having particular functions:
Optical Microscope: The very first ever produced. The optical microscopic lense has a couple of lenses that work to expand and enhance images placed in between the lower-most lens and the light source.
Basic Optical Microscope-- uses one lens, the convex lens, in the magnifying process. This sort of microscopic lense was used by Anton Van Leeuwenhoek throughout the late-sixteen and early-seventeenth centuries, around the time that the microscopic lense was invented.
Substance Optical Microscope-- has two lenses, one for the eyepiece to serve the ocular point of view and among short focal length for unbiased point of view. Several lenses work to reduce both chromatic and round aberrations so that the view is unblocked and uncorrupted.
Stereo Microscope: This is likewise known as the Dissecting Microscope, and utilizes 2 separate optical get more info shafts (for both eyes) to develop a three-dimensional image of the object through two a little different perspectives. This sort of microscope carries out microsurgery, dissection, watch-making, little circuit board production, and so on
. Inverted Microscope: This kind of microscopic lense views things from an inverted position than that of regular microscopic lens. The inverted microscope concentrates on the study of cell cultures in liquid.
Petrographic Microscope: This sort of microscopic lense includes a polarizing filter, a rotating stage, and gypsum plate. Petrographic Microscopes specialize in the study of inorganic compounds whose homes tend to modify through shifting point of view.
Pocket Microscope: This type of microscope includes a single shaft with an eye piece at one end and an adjustable unbiased lens at the other. This old-style microscopic lense has a case for easy carry.
Electron Microscopes: This sort of microscopic lense utilizes electron waves running parallel to a magnetic field supplying greater resolution. 2 Electron Microscopes are the Scanning Electron Microscope and the Transmission Electron Microscope.
Scanning Probe Microscope: This type of microscope procedures interaction between a physical probe and a sample to form a micrograph. Only surface area data can be gathered and analyzed from the sample. Kinds Of Scanning Probe Microscopes include the Atomic Force Microscope, the Scanning Tunneling Microscope, the Electric Force Microscope, and the Magnetic Force Microscope.
Science would not be what it is today without the microscope, as this gadget is the primary instrument by which the world and all of its aspects are measured and examined. It is with the microscope that we take an appearance inside of ourselves so we can understand and find out who we are and how we work.


What is laser marking?
Laser marking stands for marking or labeling parts and materials with a laser beam. Different processes are distinguished, such as engraving, removing, staining, annealing and foaming.
Depending on the material and the quality requirement, each of the following procedures has its own advantages and disadvantages.
During laser engraving, the part surface is melted and evaporated with the laser. Consequently, the laser beam removes the material skin.
The laser beam removes the top coats applied to the substrate usually the packaging. A contrast is produced as a result of the different colors of top coat and substrate base.
Common materials that are laser marked by means of removing coating material include anodized aluminum, coated metals, foils and films, or laminates.
In the staining method, the heat effect generated by the laser beam causes a chemical reaction in the material. Depending on the material composition, this will result in different color shades.
For example, if a light plastic material is discolored during laser etching, soot particles may be produced that will result in a dark marking.
Annealing marking is a special type of laser etching for metals. The heat effect of the laser beam causes an oxidation process underneath the material surface, resulting in a color change on the metal surface.
In this process the laser beam melts a material. Gas bubbles are produced in the material, which reflect the light diffusely.
The marking will turn out lighter than the areas that have not been etched. This type of laser marking is used mainly for dark plastics.
What materials can be marked with a laser?
Metals: Stainless steel, aluminum, gold, silver, titanium, bronze, platinum and copper.
Plastics: ABS, polycarbonate, P.E.T., polyamide, PMMA or plastics special with laser additives.
Packaging: coatings, foils and films.
Synthetic materials: Laminates, composites.

Why do you need Fiber Coloring Machine and what can it do for you If you have ever seen a telephone company technician working on the phone jump box outside your home, you ought to have noticed a unique handheld phone like instrument. The technician uses it to identify the incoming telephone wires by tapping onto the wires and listening for a tone. Once he finds the right wire, he connects the wire in your house.
During fiber optic network installation, maintenance, or restoration, it is additionally often necessary to identify a specific fiber without disrupting live service. This battery powered instrument seems like an extended handheld bar and is also called fiber identifier or live fiber identifier.
How does it work? You will find a slot on the surface of a fiber optic identifier. The fiber under test is inserted into the slot, then your fiber identifier performs a macro-bend on the fiber. The macro-bend makes some light leak right out of the fiber as well as the optical sensor detects it. The detector can detect both the existence of light and also the direction of light.
A fiber optic identifier can detect “no signal”, “tone” or “traffic” plus it indicates the traffic direction.
The optical signal loss induced from this strategy is so small, usually at 1dB level, that it doesn’t cause any trouble on the live traffic.
What sort of Optical Fiber Coloring Machine does it support? Fiber optic identifiers can detect 250um bare fibers, 900um tight buffered fibers, 2.0mm fiber cables, 3.0mm fiber cables, bare fiber ribbons and jacketed fiber ribbons.
Most fiber identifiers must change a head adapter so that you can support all these types of fibers and cables. While many other models are cleverly designed plus they don’t have to alter the head adapter whatsoever. Some models only support single mode fibers yet others supports both single mode and multimode fibers.
What exactly is relative power measurement? Most high end fiber optic identifiers are equipped with a Liquid crystal display which may display the optical power detected. However, this power measurement cannot be utilized for a accurate absolute power measurement of the optical signal because of inconsistencies in fiber optic cables as well as the impact of user technique on the measurements.
But this power measurement can be used to compare power levels on different fiber links which have same type of fiber optic cable. This relative power measurement has many applications as described below.
1. Identification of fibers
The relative power reading could be used to assist in the identification of the live optical fiber.There are many tests which can be performed to isolate the required fiber cable from a group of fibers without taking along the link(s). Three methods that may be used include comparing relative power, inducing macrobends, and varying the optical power of the source. No single strategy is best or necessarily definitive. Using one or a mix of these techniques may be needed to isolate the fiber.
2. Identification of high loss points
Fiber optic identifier’s relative power measurement capability could be used to identify high loss point(s) in a period of fiber. By taking relative power measurements along an area of optical fiber that is suspected of getting a very high loss point such as a fracture or tight bend, the change in relative power indicate point could be noted. When a sudden drop or increase in relative power between two points is noted, a higher loss point probably exists between the two points. The user can then narrow in on the point through taking further measurements between the two points.
3. Verify optical splices and connectors
Fiber optic identifier may be used to verify fiber optic connectors and splices. This test must be performed on the lit optical fiber. The optical fiber can be carrying a signal or even be illuminated utilizing an optical test source. Attach fiber identifier to 1 side in the optical connector/splice. Read and record the relative optical power. Repeat the measurement on the second side of the connector/splice. Go ahead and take difference between the reading on the second side and also the first side. The real difference needs to be roughly similar to the optical attenuation of the optical connector/splice. The measurement can be taken repeatedly and averaged to enhance accuracy. When the optical fiber identifier indicates high loss, the connector/slice might be defective.
Fiber optic splice closure will be the equipment utilized to offer room for fusion splicing optical fibers. Additionally, it provides protection for fused fiber joint point and fiber cables. There are mainly two kinds of closures: vertical type and horizontal type. Quite a number of fiber splice closures are designed for different applications, such as aerial, duct fiber cables and direct burial. In most cases, they may be usually used in outdoor environment, even underwater.
Fiber Optic Splice Closure Types . For outside plant splice closure, there are two major types: horizontal type and vertical type.
1) Horizontal type – Horizontal type splice closures seem like flat or cylindrical case. They whzqqc space and protection for optical cable splicing and joint. They may be mounted aerial, buried, or for underground applications. Horizontal types are used more frequently than vertical type (dome type) closures.
Most horizontal fiber closure can accommodate hundreds of Secondary Coating Line. They are designed to be waterproof and dirt proof. They may be used in temperature which range from -40°C to 85°C and can accommodate up to 106 kpa pressure. The cases are often made of high tensile construction plastic.
2) Vertical Type – Vertical form of fiber optic splice closures looks like a dome, thus also, they are called dome types. They meet the same specification since the horizontal types. They are designed for buried applications.

The research interests of Nonlinear Optics group concentrate on fundamental characterisation of new nonlinear materials and novel applications of infrared-sensitive photorefractive crystals and waveguides.
Photorefractive materials form an important part of today's optical technology. One of their most attractive features is their high nonlinearity, which can be induced with low power densities of light. We investigate the propagation and high amplification of light in rhodium doped photorefractive materials to establish optimum range of doping that enhances their performance with low energy infrared light instead of visible light. In collaboration with Imperial College we are finalising a model to characterise Rh:BaTiO3 material.
The major part of our present research concerns configurations that fully utilise the capability of photorefractive materials to efficiently amplify light. A photorefractive ring cavity offers the attractive possibility of using it for sensing applications for the detection of trace species and pollutants. This work is carried out in collaboration with the University of Southampton.
There is a need for new photosensitive materials that are as efficient and highly nonlinear as conventional photorefractive materials, but more versatile and a great deal cheaper. We have therefore started working on advanced photosensitive materials, such as recently discovered photorefractive liquid crystals and their applications in optical telecommunication.

AVEKA was approached by a customer to process rough, jagged particles into smooth, more spherical particles to ease downstream use and flowability. Due to several characteristics, including molecular weight and melt viscosity, AVEKA determined this material did not easily form the desired spheres when spray chilled/prilled.
AVEKA suggested surface modification using spheroidization to modify the customer’s material. To achieve the desired particle morphology, AVEKA performed multiple trials and optimized temperatures, spray angle, air flow rates, feed rate and nozzle configurations. AVEKA used laser light scattering to measure particle size distribution and performed scanning electron microcsopy (SEM) and digital image processing to image and quantify particle morphology. The final product was more spherical and demonstrated greatly improved powder flowability, which met the customer’s downstream processing needs.

Immenstaad, 27 September 2018: The German-French satellite MERLIN (Methane Remote Sensing LIDAR Mission) is a mission to observe the concentration of the greenhouse gas methane. In this cooperation between CNES and DLR, CNES signs responsible for the satellite bus, which is a Myriade Evolution, and DLR signs responsible for the instrument. The instrument on MERLIN is a pulsed high power LIDAR (Light Detecting and Ranging) operating precisely at the methane absorption lines at 1645.55 nm wavelength. The instrument emits two different wavelengths called ‘online’ and ‘offline’: Online means located in the absorption feature and offline beside it for reference purposes.
To enable the required emission wavelengths around 1645.5-1645.7 nm, a frequency reference unit (FRU) is part of the instrument on the satellite. The frequency reference unit contains a methane gas cell, several diode lasers (1064 nm and 1645 nm emission wavelength), a wavemeter and the associated control electronics including an FPGA for stabilizing the diode laser emissions and the high power laser pulse frequency to the methane cell and the wavemeter. The FRU is delivering its optical signals to the high power laser and measures their wavelengths and the ones of the high power laser pulses to MHz accuracy. In addition it performs the wavelength stabilization control loops for the internal diode laser and of the OPO of the high power laser.
One and a half years after the start phase C/D, SpaceTech GmbH delivered the CDR data package for the frequency reference unit to Airbus and DLR. The co-location took place on the 25th and 26th of July 2018 at the SpaceTech premises in Immenstaad, Germany. All RIDs have been closed and no showstoppers for the CDR have been found. The engineering model has been built and its final testing phase has started.
After the successful operation of the LRI on GRACE-FO in orbit, the development of the frequency reference unit is the next major C/D development activity for a laser-optical instrument at SpaceTech.
Key and driving requirements of the FRU are:
- 5 mW of optical output power at 1645 nm with a laser frequency accuracy and stability of 10 MHz
- 10 mW of optical output power at 1064 nm with less than 1 MHz linewidth
- Measurement of every single transmitted pulse with a systematic error of less than 8 MHz
- Controlling the cavity of the optical parametric oscillator in the main laser

Already proven in surveys and decontamination activities in Japan, China, and Europe, Innovative Physics’ (IPL) Hot Spot Locator (HSL) Gamma Imaging technology provides much more rapid and accurate visualisation of radiation contamination.
The first product to deploy IPL’s Imaging Mask design was the Hot Spot Locator500 (HSL500™), which was developed following the Fukushima Dai’ichi Incident to assist with clean-up operations. Now deployed by decontamination, emergency response, and nuclear management teams across the world, the technology has proven to be quick and accurate in comparison with conventional gamma imaging techniques.
The detection speed and ability to locate hot spots of very low radioactivity levels is due to its enhanced sensitivity, while the class leading accuracy of visualising the location of the hot spot is due to advanced image processing techniques developed by Innovative Physics.
Following end-user feedback and extensive field work conducted by IPL globally, IPL began development work on the next generation gamma imaging tools, HSL-Lite™ and HSL-Lite Plus™ which were launched at the start of 2016.
Utilising IPL’s new Dynamic Imaging Mask (DIM) design, these products maintain the superior speed and sensitivity of the HSL500™, but at less than half the weight of their predecessor. The HSL-Lite™ is 6.5kg and the HSL-Lite Plus™ is 10kg, making them both easily and quickly deployable by a single person.
Furthermore, the DIM system improves the quality of the gamma image by reducing the background interference not emitted from the gamma source located in the field of view.

Lens focal length is always in mm. Calculators assume sensor has aspect ratio. First enter your application parameters in Calculator 1. This will help you determine the ideal lens focal length.
You're not likely to find a lens having the exact focal length suggested by Calculator 1. Using a common lens focal length, use Calculator 2 to determine the working distance necessary to get your desired field of view.

Or, use Calculator 3 to determine the field of view resulting from a fixed working distance. Lenses having focal lengths of 6, 8, 12, 16, 25, 35 and 50 mm are commonly available. Using a shorter focal length lens decreases your working distance and therefore captures more light, but the resulting image will be more distorted.
A 16mm lens is often a good compromise. Keep in mind that a smaller sensor size will increase the working distance. Calculators assume field of view width is in direction of the camera sensor's width.
If your field of view's height is greater than it's width, consider rotating the camera 90 degress.Looking for a list of projectors that meet your throw distance and screen size needs? Find Projectors. A projector's distance from the lens to the screen surface is called the Throw Distance. The throw distance and the size of the image it produces on the screen are proportional to each other based on the optics of the lens. As you increase the distance between the projector lens and the screen the image will also increase.
A projector's distance from a screen and the size of the image it produces are proportional to each other based on the optics of the lens. As you increase the distance between the projector and a screen the image will also increase. If your projector has a zoom lens, the lens can be adjusted to change the size of the screen image without changing the distance of the projector.
Since each projector lens is different, an online projection calculator tool will help you calculate the size of an image on a screen relative to how far the projector is placed from screen. So for example, the most common projector throw ratio is 2. So if I'm using a projector with a throw ratio of 2. So the throw ratio is a simple formula that let's you easily compute throw distance or image width given that you know one of these measurements.
A projector zoom lens will have two different throw ratios, one for the minimum zoom setting and one for the maximum zoom setting. A short throw projector is a projector with a lens that has a throw ratio of 0. These projectors are ideal for rear screen applications where the area behind the screen is limited, or for a wall mounted application where the projector will be mounted within 1 or 2 feet from the screen.
The goal of these projectors is to produce as large of an image within the shortest amount of space between the projector and the screen. Find a Projector Login. Classroom Interactive Portable. Find a projector based on your desired features and specs. Throw Calculator.

Viewable Dimensions: X feet. Did you find this useful? Please share it! Simulator Mode allows you to choose from several different scenarios and visualize the effects of various lenses at a fixed distance.
This mode limits the parameters to realistic ranges for a given scene. Calculator Mode allows you to input arbitrary values for the parameters, but does not allow you to visualize the scene.
The scene selection available in Simulator Mode only allows you to choose from several scenarios, to better help you visualize your lens selection. The sensor size refers to the size of the imager array. Choosing the incorrect size will have an adverse effect on the field of view calculations, so be sure and check your camera specifications for the correct size. If you are using the Lens Simulator on a product page, this value will be preset for you. This refers to the distance of the camera from the target scene you are trying to capture, measured in feet.
In Simulator Mode, the distance is fixed for each scene and cannot be changed. The focal length refers to the distance between the sensor and lens aperture, and determines how wide or narrow your angle of view is. Shorter focal lengths provide a wider angle of view, while longer focal lengths give a narrower view angle, allowing you to zoom in on distant objects. You can manually input a focal length or use the slider to the right of the monitor.
These are the dimensions, measured in feet, of the target viewable area dimensional field of view ; in other words, what you will see on your screen. The target area will be calculated based on the distance and focal length, or you can manually input your target area to find out what focal length you would need for that view.

The online interface just works. If you have a Sprint phone and a Sprint SIM, just bring it over. Activation happens in under a minute. The network is as good as the postpaid Sprint network. I use this for a backup phone. Make sure you use your phone at least once in 3 months, leave it on airplane mode and on wifi otherwise and you have a backup phone that you can turn on and use in an emergency.Cornstarch nails
This has been a great cell phone service and very affordable for my family. My two sons are in college and they have Tello, so with that, thank you for the awesome service and for taking care of us!!!. Their customer service is outstanding, if you ever have to call them a real person answers the phone and makes sure you are satisfied before you hang up. Love love love this company My phone recently suffered water damage, so I bought a new one and tried to switch service over.
The website said I needed a new SIM card, but I didn't believe it because both phones take nano Sprint SIMs. I contacted support via chat, and they were able to explain not only that the website was correct, but that different model phones require different SKUs of Sprint SIM card to operate on the Sprint network. Support was very fast and polite, and the prices can't be beaten for a light cell phone user like me.
I highly recommend this company.Micronics flow meter price

Guangzhou Pulisi Technology Co Ltd, a national high-tech enterprise based in Huangpu district, has developed the first machine of its kind in China that uses AI machine vision to produce masks. [Photo by Jia Zihao/southcn.com]
uangzhou's Huangpu district encouraged local smart manufacturing companies to carry out research and development of automatic equipment for the production of supplies like masks and protective glasses on Feb 5.
Guangzhou Pulisi Technology Co Ltd, a national high-tech enterprise based in Huangpu dedicated to the application of artificial intelligence (AI) machine vision technology and integrated solutions for machine vision systems, has developed a fully automatic production machine for masks using AI machine vision within three days.
Lin Xiaobo, founder of Guangzhou Pulisi Technology Co Ltd, said that the R&D project started on Feb 6 and that trial production began on Feb 9.
The machine, being China's first of its kind using AI machine vision to produce masks, has started mass production on Feb 10, with a single machine able to produce 120 masks per minute and the total amount of masks produced per day exceeding over 150,000.
Compared with traditional machines, the new machine can achieve long-term operation and occupy less space.
"The development process was not easy. We have received a lot of support from the local district, as well as the upstream and downstream industry chain," added Lin.
The annual production of the new machine can reach 50 sets per month, expecting to help alleviate the shortage of masks in the country.
Applying modular flexible design, the machine can be used on the production lines of 3C (computers, communications, and consumer electronics) products.

Unique computational tools discovered cheaper and smarter LEDs phosphor in the latest research performed by a team of engineers from the University of California San Diego.
With the help of news phosphor, the research team has devised a novel prototype for the LED light bulbs with white color. The new prototype has discovered a better color quality in the leading material of while LEDs bulbs – phosphor, as compared to many other commercial LEDs available currently in the world’s market.
LEDs’ key ingredient, i.e. luminous phosphors is the light emitting substance that comes in the form of crystalline powders. It absorbs energy from the closer –UV or blue light and then in visible spectrum, it emits white light by forming a combination of different colors of light. Phosphor is made up of some earth elements that are rarely found, so that they are very expensive, while others are manufactured with a few difficulties and poor color quality.
To overcome these issues a team scientists from the Chonnam National University and UC San Diego developed and discovered a new sort of phosphor. The team has made the new substance of its kind by including most of the earth-abundant elements with the help of some industrial methods. The new discovery produces potentially impressive LEDs that provide more vivid and accurate colors.
Study’s leading investigator, Prof Shyue Ping Ong from the Jacobs School of Engineering at the UC San Diego stated that, “Calculations are quick, scalable and cheap. Using computers, we can rapidly screen thousands of materials and predict candidates for new materials that have not yet been discovered.”

A fiber optic conveyor has been developed for investigating the travel-time difference between two counter-propagating light beams in uniformly moving fiber. Our finding is that there is a travel-time difference Δt = 2vΔl/c2 in a fiber segment of length Δl moving with the source and detector at a speed v, whether the segment is moving uniformly or circularly.

We present the design for a high resolution triple-grating Czerny-Turner spectrometer for visible and telecom wavelengths, together with results of optical simulations using ZEMAX. Results from the simulations show that one of the most important factors affecting spectral resolution is the focal length of mirrors. Increasing the focal length allows for a greater degree of spatial dispersion of light diffracted from the gratings and also reduces optical aberrations. Radiation of wavelengths around 1550 nm are shown to have very noticeable aberrations in certain designs, evident by a large degree of smudging. Using parabolic mirrors instead of spherical mirrors is demonstrated to have a negligible effect when compared with increasing focal length. The optical simulations and preliminary testing of mechanical components show that it is possible to build a cost effective high resolution Czerny-Turner spectrometer using off the shelf components.
Optical spectrometry is a process of analyzing the spectrum of light. It has a broad range of applications in areas such as astronomy, chemistry, and photonics. For example, Raman spectrometry may be used to identify the presence of certain molecules in an unknown sample, and Rayleigh scattering spectroscopy may be used to investigate the properties of an individual single walled carbon nanotube . High-resolution spectroscopy capable of resolving spectral features spaced by less than ~10pm is in particular extremely useful for characterizing the spectral properties of solid state quantum emitters, such as self-assembled quantum dots, and semiconductor micro-cavities and photonic-crystal nano-cavities with high Q-factors.
Here we present the design for a high-resolution Czerny-Turner spectrometer with a focal length as long as 1.5m and three diffraction gratings. While such spectrometers are currently available on the market, they are manufactured in very small volumes, which results in prices exceeding $100k.
A spectrometer generally consists of a monochromator, which separates the wavelengths of the incident light into different propagation directions, and of a calibrated one- or two-dimensional photodetector, that detects the relative intensities of light at each wavelength. The monochromator most often utilizes a diffraction grating with adjustable tilt, while the detector is usually a high-sensitivity CCD or CMOS camera for visible light spectrometers and InGaAs diode array for telecom wavelengths.
In a Czerny-Turner monochromator/spectrometer, the input light is focused through a narrow slit, then collimated by a concave mirror with a focal length f, after which it propagates for a distance f where it hits a diffraction grating. Here, light of different wavelengths is reflected under different angles and, after traveling for a distance f, it is refocused onto the detector with another concave mirror with focal length f.
Our spectrometer was not fully built since many critical optical components had lead times of several months and would not arrive while Karl was still present at the University of Waterloo. However, thorough optical simulations predicting the capabilities of the instrument were performed using ZEMAX. Additionally, a prototype of a two-axial rotating turret allowing automated swap between the deployed diffraction gratings, which was called the TRISPEC, was built and is reported here.
Mechanical devices such as the TRISPEC, camera holder, mirror holders for 4”-diameter concave mirrors with 50cm focal length, and periscope were custom machined.
The acronym TRISPEC comes from TRIple Turret SPECtrometer, and refers to the target design feature that will allow the user to switch between active diffraction gratings. The ability to select which grating is used is important since each grating has a different number of groves/mm, resulting in different degrees of spatial dispersion of light. Therefore, the bandwidth of light which falls on the detector can be controlled by changing the diffraction grating. This allows the user to be able to select between examining a broad spectrum of light, and progressively select narrower bands of light for more accurate inspection of a particular part of the spectrum.
The simplest design for a triple turret would be to have, for example, one diffraction grating positioned on each of three faces of a triangle and this is in fact used in some of the commercially available spectrometers, such as Acton SP-2750 from Princeton Instruments. Switching a grating is then be a matter of rotating the triangle by 120°. A problem with this design, however, is that any further angular adjustment (to focus in on a spectral region) would have an axis of rotation which is not about the face of the grating. This causes the grating the partially move out of the incident light beam for more extreme tilt angles, which in turn limits the efficiency and wavelength range of the grating.
The TRISPEC design presented here solves this problem by using two axes of rotation. One is for selecting gratings and the other is for fine angular adjustments of the selected grating. A picture and schematic of the TRISPEC are shown in figures 1 and 2. The Parker rotation stage, Kohzu rotation stage, servo motors, and motor control were purchased online. All other materials were custom machined using 6061 aluminum in the student machine shop at the University of Waterloo. The mode of operation of the TRISPEC is as follows. For fine angular adjustments of a chosen grating the Parker stage is controlled. This is done with an STM-200 Stepper Motor, which provides more torque but also requires more current than the NEMA-17. To swap gratings, the Kohzu stage is controlled with the NEMA-17 motor. Both motors are controlled by an Arduino Uno and an Adafruit Motor shield. The motor shield is used since the amount of current outputted by the Arduino is not enough to power the motors. Connecting an external DC power supply to the motor shield permits higher power control of the servo motors, as well as control with useful waveforms resulting in microstepping and double coil steps. Using the Motorshield with 1.2 A and 8V is enough to operate the TRISPEC. How the TRISPEC fits in to the entire design of the spectrometer can be seen in Fig. 8.
Another important mechanical part of the spectrometer is the Periscope. In many optics labs, the beam height above optics table is kept at ~10 cm, as this provides a good compromise between mechanical stability of the beam steering components and convenience for manual alignment. However, given the large are gratings dictated by the long-focal length of the spectrometer and the use of two rotation stages for the grating turret, the resulting optical axis of the instrument is at roughly 17 cm. Therefore, a device is needed to raise the input beam from the optics table. The design for the Periscope is shown in figure 3. A parabolic mirror is chosen over a plane mirror so that the periscope may be used to raise the optical axis as well as focus the input light with minimized chromatic and spherical aberration. Adjustment rods and an XY adjuster are used since they allow for fine positioning of the parabolic mirror so that light very precisely passes through the entrance slits of the spectrometer.
In addition to prototyping several devices necessary to construct the spectrometer, thorough simulations using Zemax Optic Studio were performed to assess the effectiveness of various design decisions. Decisions include choosing parabolic or spherical mirrors, the number of groves/mm of a diffraction grating, the focal length of mirrors, and the geometry of the components (i.e., the spacing between mirrors and TRISPEC, entrance slit and mirrors, etc).
Figures 4-7 summarize the results from the ZEMAX simulations. Figures 4 and 5 were generated using 75 mm diameter, 500 mm focal length silver coated spherical mirrors, a 1” diameter 30 mm focal length achromatic doublet, and a 4 mm initial collimated waist of light. The spectrometer was designed in sequential mode in ZEMAX. This allows for fast and precise positioning of optical elements. However, only one wavelength of light may be analyzed at a time in sequential mode, so the whole design was converted to non-sequential mode for multi-wavelength analysis. In non-sequential mode, the spectral resolution can be more effectively studied since comparing two wavelengths side by side allows one to see the effects of optical aberrations and dispersion due to different gratings more clearly. Figures 5 and 7 show graphically what the signal processing software to determine intensity of a certain wavelength would do. The graphs show the sum of the irradiance along a column of pixels. This is useful since in practice wavelength is determined by which column of pixels light is incident upon. If the two blue spikes are clearly spatially separated, then that is an indication that there exists distinct spectral resolution between the two wavelengths. How symmetrical the two peaks are indicate to what extent optical aberrations are present. The simulations show that a high degree of smudging results from using long wavelength light (~1550 nm wavelength) with diffraction gratings of 1200 groves/mm or higher. Intuitively, one might expect the greater amount of spatial dispersion resulting at longer wavelengths to positively contribute more to spectral resolution than any negative side effects such as aberrations would. However, the increase in full width 1/10th maximum cancels out the positive effects that greater dispersion would have on spectral resolution.
Full width 1/10th maximum is a measure of how horizontally concentrated light energy is on the detector. It is the spatial distance of the irradiance going from 10% of its maximal value, to its maximal value, and back down to 10% of its maximal value along a horizontal axis. The full width 1/10th maximum is relatively large for 1550 nm wavelength light and a 1200 groves/mm grating. Therefore, this combination of wavelength and gratings should be avoided. An important conclusion from these simulations is that full width 1/10 th maximum is mainly a function of wavelength and not number of lines/mm of the diffraction grating. For example, the full width 1/10th maximum does not change significantly when using either 1200 or 1800 lines/mm. However, prohibitively large full width 1/10th maximum occurs when using ~1500 nm light. One might expect that with a higher rules/mm diffraction grating more aberrations (such as smudging) would occur since light is dispersed at greater angles. This effect is noticeable but is not nearly as dominant as the effects of wavelength are. Figures 6 and 7 show the effects of focal length on spectral resolution. Clearly, with greater focal length there is more distinct separation of wavelengths. All of the figures show light of 852 and 852.01 nm wavelength. Figure 7 shows that with greater focal length asymmetries in the light hitting the detector are reduced. This is because a smaller tilt of the diffraction grating is needed with higher focal lengths. Less tilt means the light is better able to remain collimated. Figures 6 and 7 also compare the effects of using a parabolic as opposed to spherical mirror. The reduction of spherical aberrations resulting from using parabolic mirrors is negligible, since greater focal lengths have a much more dominant effect in improving spectral resolution.
Summary and conclusion
A high spectral resolution spectrometer was designed and several main components of it were prototyped. Complete construction of the spectrometer was not possible since critical optical components would not arrive in time. However, thorough ZEMAX simulations were performed for the high resolution spectrometer as well as multiple other configurations. The ZEMAX simulations show that spectral resolution is directly proportional to focal length. Additionally, optical aberrations are reduced with shorter wavelengths of light (850 nm vs 1550 nm). One part of the spectrometer which was built is the TRISPEC. This device allows the user to select one of three diffraction gratings to be active, as well as finely adjust the angular position of the selected grating about the face of the grating. This device is controlled by two servo motors, an Arduino Uno, and an Adafruit motor shield. Looking forward, decisions must be made as to whether a composite grating system as opposed to a single grating on each face of the TRISPEC will be used. This decision would affect how the TRISPEC is built. The presented model was built to allow a composite grating to be attached. This is so that off the shelf gratings can be used and also to make the design more affordable. In order to build a spectrometer with the highest spectral resolution, long focal lengths such as 152 cm (60”) should be used. This would also reduce optical aberrations. Ideally, parabolic mirrors would also be used, but the effects of focal length are much more dominant than the type of curvature. With these design decisions in mind, a cost efficient spectrometer which minimizes aberrations and provides high spectral resolution can be built.
