Shematic view of Laser Interferometrer Gravitational Wave Detector.
Interferometric detectors are regarded as promising devices for gravitational wave detection. Since the effects of gravitational waves appear as a fluctuation of optical path length, it is required to detect the phase differences between two orthogonal light paths of a Michelson type interferometer. To achieve a sensitive detection, a method called "RF Dark Fringe Locking" is generally used. Phase modulation applied by Electro-Optic(EO) modulators the interferometer move the measurement band to high frequencies. To realize a long optical path length in the interferometer, a multi-pass geometry called optical delay-line or Fabry-Perot cavity is used. One of the interfering output beams is detected by a photo detector, and its intensity is held to a minimum of interference(dark fringe) by a servo system.

Treatment of blood vessels on the face and body can be performed safely and effectively using lasers and light devices. Blood vessels are located beneath the epidermis (superficial skin) in the dermis of the skin. Procedures to remove unwanted vessels need to be able to reach these deeper structures without damaging the epidermis. Lasers and light devices can accomplish this using a method termed ‘selective photothermolysis’. Basically, this means that the light gets selectively absorbed by the target (blood vessels for example) without damaging the surrounding tissues. Hemoglobin, the oxygen carrying component of blood, is able to absorb light of different wavelengths. Various lasers can be used targeting hemoglobin and sparing the other tissues.
Vascular lasers and light devices come in a variety of wavelengths. Hemoglobin can absorb light at many different wavelengths, which means that many devices exist for possible use. Short wavelength devices such as the potassium titanyl phosphate laser (KTP, 532nm), and the pulsed dye laser (PDL 585, 595nm) are popular choices since hemoglobin easily absorbs light at these wavelengths. However, short wavelengths sometimes don’t penetrate to a deep enough level, making treatment of areas with thicker skin, typically off the face, more difficult. Longer wavelengths, with deeper penetration, can also be used. The Neodynium Yag laser (Nd:Yag, 1064nm) and several diode lasers (800-940nm) are employed on thicker skin areas, and on deeper vessels, such as those of the legs. These wavelengths are less well absorbed by hemoglobin, but penetrate deeper. The Alexandrite laser has also recently been used for vascular lesions. With a wavelength of 755nm, its properties lie somewhere between the two groups described above. Though, at the current time, the primary use of the Alexandrite laser is still for laser hair removal and pigmented lesions. Intense pulsed light devices (IPLs) are also used to treat vascular lesions and have recently been gaining in popularity for this indication. Several vascular lasers of the past (argon, copper vapor, krypton) are no longer in use due to their increased risk for complications.
Vascular lasers can be used to treat various conditions besides telangiectasias (blood vessels). Red lesions of the skin also respond well to these treatments. Acne, acne scarring, hypertrophic (raised and thick) scars, hemangiomas, port wine stains, striae (stretch marks), photodamage, rosacea, and verrucae (warts) are other common uses for vascular lasers. All of these conditions have one thing in common, and that is the color red. Most red lesions will absorb the light emitted by vascular lasers and are possibilities for treatment with these devices.
The shorter wavelengths vascular lasers are also absorbed by melanin in the skin. Melanin gives skin dark color. For this reason, these devices come equipped with a cooling attachment. The cooling protects the epidermis from the laser, while the laser penetrates deeper into the dermis where the vessels are located. Without cooling, treatment with the short wavelength vascular lasers (PDL, KTP) can burn the epidermis. The longer wavelength lasers (diodes and Nd: Yag) are not well absorbed by melanin and pose less of a risk for epidermal damage, though it can occur. That being said, the short wavelength lasers with proper cooling can be used safely and effective in dark skin types.
The procedure is slightly different depending on which laser is used. Most of the vascular lasers do not require numbing cream. Treatment of vascular birthmarks (hemangiomas or port wine stains), or treatment of pediatric patients warrants topical anesthesia. Several sessions for optimal results are generally required. However, one session will show improvement. Treatment sessions last from 5 minutes to 30 minutes depending on the area being treated. Prior to treatment the face should be clean and free of any topicals, including sunscreen or makeup. After treatment, the skin can stay red for up to 48 hours. Some treatments with the pulsed dye laser can leave the skin with bruising for 5-7 days. Bruising is as result of the vessels being broken by the laser. This is not considered a complication, but can be difficult to conceal with makeup. Treatment of vascular birthmarks is typically performed at doses that cause bruising, but treatment of other conditions use lower energies and have little to none.
The pulsed dye laser (PDL) has been the workhorse of the vascular lasers for a long time. It has always been considered to be the most effective of its group. In recent studies, however, several new IPLs have been shown to be at least as effective in some cases. PDL is still the most popular of the vascular lasers, but expect others to gain recognition as these devices become more sophisticated.
Laser treatment for any indication should be tailored to the each specific case. For vascular lasers, this includes the size of the vessel, the depth of the vessel, the patient’s skin type and location of the area to be treated. The laser’s parameters (wavelength, cooling, treatment time etc.) should be adjusted for optimal efficacy and safety with each treatment.
Possible complications of vascular lasers include pigment changes, erythema (redness), crusting and blistering. Blistering can lead to scarring. In addition, dark hair will be temporarily removed in the area of treatment, but will re-grow after treatment. Protective eyewear should be worn by everyone in the room at all times when the laser is in operating mode.

Wallops Island, Virginia – A decade or so ago, laser communication was one of the tools of the trade for establishing high-speed broadband connections between two points before fiber became plentiful. Now NASA has two projects in the works to demonstrate optical links across tens and hundreds of thousands of miles for satellite use, bringing a totally new meaning to “free space” communications.
NASA’s first demonstration will take place in a few weeks, as the LADEE satellite circles around the Moon. Onboard the 393 kilogram satellite is the Lunar Laser Communications Demonstration (LLCD). As LADEE settles in, LLCD will use a near-infrared laser to pump data downstream at speeds up to 622 Mbps, with an uplink speed around 20 Mbps.

LLCD is a 65 pound system made up of an optical module, a modem module and a controller electronics module. A 10 centimeter wide telescope onboard the satellite will point a 0.5-watt infrared laser – the same type used in ground-based fiber optic cables -- at one of three receiving stations on earth, where the now 5 kilometer wide beam (yes, it’s a LOT of spread) will be picked up by a cluster of four 17 inch telescopes used to collect and focus the signals into optical fiber and detectors. A cluster of four 6 inch telescopes are used to send a beacon to the satellite for pointing, as well as uplink data.
Two reception sites are located in the United States with a third in Europe - White Sands, New Mexico, JPL’s Optical Communications Telescope Lab in Wrightwood, California, and the European Space Agency’s Optical Ground Station in Tenrite, Spain. A six month study of sites around the world was conducted to find the right balance of clear skies – clouds/fog/rain and lasers don’t mix – and access to high-speed ground broadband. Researchers didn’t want to pull 622 Mbps down only to bottleneck into 45 Mbps speeds on the ground.
A spokesperson working on LLCD said the 622 Mbps downlink speed is a significant increase over the roughly 100 Mbps Ka-band systems used on a previous lunar mission. A NASA glossy says that while an HD movie downloaded at current radio transmission rates would take over 60 minutes, LLCD would be able to down load a same-length video in under eight.
NASA’s next laser communications demonstration project will be closer to home and go faster. The Laser Communications Relay Demonstration (LCRD) is expected to be launched as a hosted payload onboard a Space Systems/Loral communications satellite in 2017. LRCD will operate for two years, using a pair of optical terminals in geosynchronous orbit to transmit at speeds up to 1.25 Gbps in both directions.
Successfully demonstrations of optical communications will allow NASA to put bandwidth-intensive instruments, such as hyperspectral images and SAR radar, on planetary probes. It will also open up optical communications to be used for data in satellites closer to earth, allowing designers to pack more bandwidth into a smaller, more power-efficient footprint.

The core component of the passive infrared device is an infrared detector (infrared sensor). Through the cooperation of the optical system, it can detect the change of thermal radiation in a certain stereo space. When there is no target such as a moving body in the prevention area, since all background objects (such as walls, furniture, etc.) have relatively small infrared radiation energy at room temperature and are basically stable, all alarms cannot be triggered. When a human body moves around the detection area, it will cause a change in the energy of the infrared heat radiation. The infrared sensor converts the received infrared heat radiation energy between the active human body and the background object into a corresponding electrical signal, and after appropriate processing, sends it to the alarm controller to issue an alarm signal. This product adopts the detector of all digital CPU processor and advanced fuzzy logic control technology to ensure the detection range and enhance the stability and anti-RF, strong light interference and other characteristics. The built-in sensitivity selection function and temperature compensation circuit ensure the detection distance in different temperature environments to avoid false alarms caused by environmental interference.

DJI Announces Swap Service for Mavic 2 Pro and DJI Mavic 2 Zoom
DJI has finally announced the predecessor to its popular Mavic camera, and there are two of them: The Mavic 2 Pro and Mavic 2 Zoom. Both great options, each camera has an 8 GB internal storage and is powered by a 3830 mAh battery.
“The Mavic 2 is the most advanced DJI camera drone ever built, designed for professionals, aerial photographers and content creators,” says the company. “Incorporating the iconic folding design of the world’s most popular Mavic Pro, the Mavic 2 is a powerful platform with new gimbal-stabilized cameras and advanced intelligent features like Hyperlapse and ActiveTrack for easier and more dynamic storytelling. With an impressive flight time of up to 31 minutes and a more stable video transmission system, Mavic 2 delivers the optimal flight experience for capturing epic shots.”
However, the Mavic 2 Pro and Mavic 2 Zoom feature some important differences. The company has also announced a new swapping service so that users can upgrade their camera assemblies.
The Mavic 2 Zoom can record from a distance with its hybrid zoom system and 24-48mm lens. This results in more compression (you won’t be able to do this with the DJI Mavic 2 Pro). DJI says that the camera is the first foldable consumer drone to come with optical zoom.
The Mavic 2 Zoom also has a Dolly Zoom effect and a 12 MP camera with a 1/2.3 inch CMOS sensor. Finally, the camera is able to capture a crisp 48 MP Super Resolution Photo by taking multiple images and then stitching them together.
The price of the Mavic 2 Zoom is $1,249.
However, the DJI Mavic 2 Pro, made by Swedish camera maker Hasselblad, has a larger 1″ CMOS sensor that records using its 10-bit DLog-m. It can also get a 20-bit HDR video. The camera also features an adjustable aperture that can go from f/2.8 to f/11 and has a fixed 24mm wide angle lens.
The DJI Mavic 2 Pro can shoot videos in the 4K video at 30fps, 720p at 120fps and H.265 codec. In the camera’s sports mode, the drone can be used at a maximum speed of 44 mph.

New Swapping Service
You cannot release a Mavic 2 camera from its gimbal assembly and swap it out the way you can with an Inspire 2 camera. For safety reasons, DJI is not selling the Zoom and Pro cameras individually so you can swap them out. Instead, DJI has announced a swapping service operated through the company’s tech support locations, similar to the way Canon has a PL to EF mount swap. Details and costs of the program have not yet been released, but many filmmakers are excited about the opportunity to update their cameras.
The company has warned users against trying to swap the cameras out themselves; this is not recommended because it could damage the equipment and require an expensive repair.
Do you think you’ll be using the DJI Mavic Pro 2 or the DJI Mavic Pro Zoom? And would you partake in the new swapping service? Let us know in the comments!

The Photonics and Fiber Optics Lab is actively involved in outreach activities aimed at raising awareness about this exciting field of science among our local community, particularly among middle school and high school students and teachers.
We are fortunate that the demonstration of optics and photonics concepts is so visually reach, eye-pleasing and immediately intuitive at any school age, even to students without substantial education in Math and Science. This, we believe, makes Optics and Photonics the ideal topic to introduce to middle and high-school students, as a vehicle to spark their interest in Science in general, and in Optics and Photonics in particular. To this end, over the course of the past two years, the lab has hosted several demonstrations in support of such university-wide activities as Kamp Kettering, DiscoverU, 21st Century Woman, and Discover Kettering open house. Demonstrations in optical fibers, illumination, lasers, holography and imaging have been included. The pictures on this page are a cross section of these activities.
The content of this page was prepared by Dr. Corneliu Rablau, Associate Professor of Physics at Kettering University, Director of the Photonics and Fiber Optics Lab.


Recently, the research team led by Prof. Liu Shengzhong and Dr. Yang Dong of Shaanxi Normal University's School of Materials Science and Engineering, has prepared a high-performance planar-type perovskite solar cell with ionic liquid (IL) modification TiO2 as the electron transport materials (ETLs), and the efficiency of their solar cells is as high as 19.62%, the highest value ever reported so far for planar-type devices.
In the last few years, organometal-trihalide perovskites have been recognized as the most promising absorber materials for low-cost, high efficiency solar cells because of their superior properties including strong light absorption, long range charge-carrier diffusion, high carrier lifetime, and apparent tolerance to defects. The ETL with excellent photoelectronic properties is very crucial in high performance of perovskite solar cells.
In their previous work, the team used the IL with high electron mobility and good transmittance as ETL to fabricate the flexible perovskite solar cells and the efficiency reached 16.09%, the highest value reported by that time. (Adv. Mater., 2016, 28, 5206-5213)
This time, they employed the IL modification TiO2 (m-TiO2) as ETLs to fabricate the hysteresis-free planar-type perovskite solar cells and the efficiency reached as high as 19.62%, the highest value reported so far for planar-type devices. The electron mobility of TiO2 ETL is enhanced and its Fermi level moves upward after IL modification, which is beneficial to the export of the electrons in the device. Both experimental analyses and theoretical calculations reveal that the anion group of the IL bonds to TiO2, leading to higher electron mobility and well-matched Fermi level. Meanwhile, the cation group interfaces with adjacent perovskite grains to provide an effective channel for electron transport and a suitable setting to grow low trap-state density perovskite for improved device performance. In light of the effective surface modification, which is so straightforward and economic, it is anticipated to be viable for large-scale roll-to-roll production.
The research was recently published under the title “Surface optimization to eliminate hysteresis for record efficiency planar perovskite solar cells” in the journal Energy & Environmental Science (Impact Factor: 25.427) (Energy Environ. Sci., 2016, DOI: 10.1039/C6EE02139E).


SOLAR COLLECTORS REINVENTED
The slat-array concentrator (SAC) is an arc-shaped lightweight structure which collects incident sunlight from a large area and concentrates all that light onto a narrow strip (focal line) below. SAC is formed by an array of slat-like reflectors (hence its name) which is is a move toward replacing a continuous surface of the parabolic trough mirror with an array of much less expensive reflective slats.
The slat-array has a quite unique optical configuration although some analogy can be drawn with the optical design known as the linear Fresnel reflector (LFR). However, the principal difference between SAC and LFR is that the slat reflectors of SAC are inclined at more oblique angles to the normal of the concentrator’s aperture. This results in the convergent beam of sunlight passing through the concentrator structure into the spaces between the adjacent reflectors. Thus, SAC is a forward-reflecting optical system with the focus on the rear whereas LFR is a retro-reflecting system with the focus formed above the collector.

In the previous article , we looked into blue light from the consumers’ perspective. The Gunnars definitely look cool, but they don’t suit me as well as the green ones do. The Phenom looks a lot like the glasses that Yu Narukami wears in Persona 4, however, so if you need something for your cosplay outfit, they might work. GUNNAR patented lens technology reduces glare, and Absorbs and reflects high-energy blue light that can strain your eyes and disrupt your sleep cycle.
They can cost anywhere from $69 to more than $100 — a pretty steep price to pay for a pair of gaming glasses. I usually work an calibrated monitor in dim natural light and everything is fine (the right font and aliasing settings help a lot too). This is another big and obvious advantage as far as these glasses are concerned. The second big advantage that gaming glass manufacturers claim is that they are actually good for your health! The secretly placed spring hinges allows the frame of the gaming glasses to adjust to any shape and size of the head of its user. GUNNAR lens coatings reduce glare and reflective light to eliminate visual distraction and stress.
If this is something you’re considering, then it’s important that your glasses look sensible enough to be worn around the office, and not like something out of a Sci-Fi adventure. The downside is that you’ll need to order these directly from the manufacturer after supplying a prescription or through a licensed optical retailer.
In case you don’t know what gaming glasses are, we’ll start with a quick lesson: these are specifically designed glasses for those who spend a lot of time in front of the computer. Anti-reflective coating brands for prescription (and non-prescription) glasses include Crizal, Zeiss, and Teflon. When there’s no time to blink, MLG PHANTOM gaming glasses by GUNNAR doesn’t disappoint. Smite is a competitive game, fitting in with the targeted audience of gaming glasses, so it made sense.
In terms of build quality, glasses are typically somewhat delicate but I didn’t notice any scratches, frame distortion or general ‘cheapness’ in the SteelSeries pair that I tested. The J+S Vision Blues were definitely the best set of gaming glasses we looked at, and we had no choice but to give them the number 1 spot on our list. Anyway I eventually bought these things anyway only because I trust Amazon to take them back if they are rubbish. Drop us a note below or call us and our eSportRx opticians will help you create your custom gaming glasses for your games.
They are a quality product and while the cheap/generic brands one do work they are typically gaudy and poorly made. At only 20 grams, these glasses are super-lightweight, and the curvature of the glass protects the eye from light even coming from the side. I’m assuming that the yellow filters the blue, and that’s basically all there is to it. Assuming that’s true (somebody below said he grabbed cheap hunting glasses that worked exactly as well as https://glassysunhaters.com/ Gunnars), there’s really no reason to go for one of these specialized brands. They also have screen protectors for gaming systems like the 3DS that filter out the blue light before it gets to your eyes. The Onyx glasses also look too much like gun-range eyewear for me to use them every day. Different frames with Premium Rx lenses range from $319 to $369, and glasses with the step-down Standard Rx prescription lenses can be found for $219 to $299.

Optical Proximity Switch
Optical Proximity Switches Manufacturers, Suppliers, Exporters & Distributors in India
Beam of invisible pulsed modulated infra – red light is produced by emitter. This beam is sensed by receiver at another end (in through beam version) or reflected by object and received by receiver placed near emitter (in diffuse version). When this beam is interrupted by object, the receiver signal gets changed and signal is produced.
Optical proximity switches are used where higher sensing distance is required with non contact operation. The object can be sensed by three methods
Through Beam Type
Transmitter and receiver are enclosed in two separate housings. When they are aligned, light beam travels from transmitter to receiver. Object breaking the light beam causes a change in the receiver. This change is detected and output signal is produced to drive external relay.
Retro Reflective Type
Transmitter and receiver are housed in single housing and aligned with the reflector. The beam reflected by the reflector gets back to the receiver. Object breaking the light beam causes a change at the receiver. This change initiates an output signal.
Difused Reflective Type
This is a fixed focused type of switch. Transmitter and receiver enclosed in one housing. Transmitted beam strikes on the object (when the object enters the scanning range) and gets reflected by object surface. Receiver detects these rays and output signal is produced.
Special built in sensitivity adjustment tempot is incorporated to adjust required sensitivity at the site
Colour Mark Sensor
These are used to sense dark colour marks on packaging material. Transmitter and receiver are housed in single housing and beam is focused to a spot. In normal condition receiver receives reflected light. When dark register mark is entered, the receiver senses change in signal level. Thus output signal is initiated.
A special modulating circuit is developed and used in all Powertech optical sensors to make them unique for working in adverse atmospheric conditions.

Go for LED: Why choose LED for your lighting?
LED lighting becomes an essential part of our advanced world and the new trend in lighting technology. It is recommended to use most energy key players and professionals as it is better compared to other lighting’s, but why? As you read this article you will learn the importance and benefits of switching to and choosing LED.
Let’s get to know more about LED.
The basics of LED lighting
LED stands for Lighting Emitting Diode. It is a type of semiconductor device that emits light rays. How do they work? When an electrical current passes through a microchip which converts electricity into light, the result is visible light.
This technology has been around for years and has been widely used for quite some time now as street lights, LED spotlights, rope lights, LED flood lights, and lighting solutions for home and commercial.
Compared to the standard bulb or halogen light, LEDs
- Produce light approximately 90% more efficiently than incandescent light bulbs.
- Are smaller in terms of size, provide unique design opportunities.
- Consume less energy, resulting in lower utility costs.
- Are proven to be more durable and reliable as LEDs contain no glass, they are less susceptible to breakage.
- Last longer. High quality LED lighting last up to 50 times longer than incandescent light bulbs.
- Do not contain harmful toxins. CFL bulbs contain mercury, which is dangerous to your health when they break.
- Do not emit UV rays. Long-term exposure to ultraviolet light is not advisable.
- LEDs emit more Lumens per watt than standard incandescent or fluorescent lighting.
Why should you switch to and choose LED
LEDs use about 50% less electricity than incandescent, fluorescent and halogen lighting. It reduces 70-90% of energy costs compared to a traditional one. LED lights also aim light in a specific direction, which means they emit light in a single direction where fluorescent and incandescent bulbs emit light and heat in all directions. This directional lighting capability reduces wasted light and energy.
Quality LEDs have an expected lifespan of 30,000-50,000 hours or even longer while a typical incandescent bulb lasts only about 1,000 hours, and a comparable compact fluorescent lasts 8,000 to 10,000 hours.
In addition to this, LEDs do not “burn out” or fail, unlike incandescent bulbs which 90% of their energy released as heat. LED does not emit heat the way a traditional bulb does as it has a heat sink, which is a passive device that absorbs the heat produced, this keeps LEDs from overheating and burning out.LED lighting reduces the expenditures of replacing bulbs in commercial and home property.
Cold temperature operation
LEDs are still working efficiently in the cold, unlike fluorescent bulbs which needed a higher voltage to start at low temperatures. LED performance increases when temperatures drop. This makes LEDs are suitable for refrigerated display cabinets, cases, freezers, and cold storage.
Traditional lighting usually contains in a glass which vulnerable to damage. On the other hand, LEDs are not using any glass instead they are mounted on a circuit board and connected with soldered leads similar to small electronic devices. LEDs are breakage resistant and free vibrations and other impacts.
LEDs come on at 100% brightness the time you switched it on compared to most fluorescent and HID lamps that do not provide full brightness the moment they’re switched on. Some requiring three minutes or more to reach the maximum light output. For business and commercial, this can be advantageous during a power outage or any employees open the store during early morning hours when it is still dark outside.
Rapid Cycling and Controllability
Traditional light sources tend to have a shorter lifespan the more they’re switched on and off while LED’s are semiconductor devices and have flashing light displays capability. It makes LED’s unaffected by rapid cycling and well compatible with daylight sensors and controls. Some LED’s can even be dimmed to 10% of light output while most fluorescent s only reach about 30% of full brightness.
When a LED bulb break, you would not worry about your kids, pet or even yourself as they are mercury free. It also made mostly of metal and plastic rather than glass and a fragile filament which is more harmful when damage. Another thing is, a majority of the power used by incandescent bulbs converted into infrared (IR) or radiated heat. Excessive heat and ultraviolet radiation are a hazard to consumer’s health. LEDs emit no IR and UV.
LEDs can be combined in any shape to produce highly efficient illumination. It can also be dimmed, resulting in dynamic control of light, color and distribution. Well-designed LED can achieve fantastic lighting effects for the eye, mood, and mind.
Common LED colors include amber, red, green and blue. To produce white light, different color LEDs are combined or covered a yellowish material phosphor. Colored LEDs are widely used as signal lights and indicator lights, like the power button on a computer.
LEDs provide 100 or even up to 200 lumens per watt. In contrast to this, CFLs use about twice the amount of watts and incandescent light bulbs around 10x as much power with only 18-20 lumen per watts.
LED lights to use less power (watts) per unit light (lumen) generated. It means, they are not just much longer-lasting in lifespan but also lower your electricity consumption.
Choose LED for your lighting needs!


FOXTENN revolutionizes accuracy by using more than 40 ultra high-speed cameras (2.500 fps), which are capable of generating more than 100.000 images per second. It basically catches everything that happens on the court; anywhere from minute detail to every unthinkable angle.
Precision is also guaranteed by the positions of the cameras at the end of the court lines, at ground level, in order to be able to see exactly how the ball bounces as close as possible. Being able to see the ball from the ground allows the system to notice the actual contact of ball's lower curve and the real contact mark on the surface, which is not possible in the case of an elevated camera like the ones being used in the current traditional systems.
Moreover, FOXTENN uses a high-speed laser scanner system in combination with the cameras in order to track each and every movement the player takes and every bounce of the ball within millimeters, which makes the system incredibly accurate, reliable and unique.

Real-time “Head Up” Posture for Comfort and Productivity
PromiseVision 3D™ imaging technology eliminates binocular eyepieces and
replaces them with a completely natural, intuitive three dimensional image with
no loss in magnification, clarity, and illumination.
DENTAL MICROSCOPES DON'T MEASURE UP
For 20 years, dental microscopes have been the “Standard of Care” in Endodontics. Advantages of Dental Microscopes include magnification and clarity, co-axial illumination and the potential for better diagnosis and treatment. But there are disadvantages associated with the binocular eyepieces:
· Unnatural static head position, leading to fatigue
· Elevated hand position, leading to fatigue and back strain
· Elimination of peripheral vision, causing slow transfer of instruments and materials from assistant and wasting time
· Elimination of peripheral vision, causing reduced patient rapport and patient awareness
· Very short depth-of-field (typically 3–4mm) leading to frequent fine focus adjustment to inspect treatment and to accommodate patient movements
· Time lost switching from eyepiece view to direct view due to change of focal distance (from infinity) to 20˝distance and adjustment in light intensity
· The very bright illumination that assists the endodontist may be uncomfortable for the assistant
The NEW STANDARD OF CARE
PromiseVision 3D™ gives you more by eliminating the challenges associated with binocular eyepieces:
· Freedom of movement and less fatigue
· Ergonomically correct posture independent of the instrument
· Restored peripheral vision for improved productivity
· Improved patient awareness and rapport
· Unprecedented depth-of-field (30mm) nearly eliminates fine focus adjustments
· No lost time when switching from binoculars to a direct view
· An intuitive 3D image with no learning curve
· Normal depth perception comparable to a direct view
The New Standard of Care for Endodontists and Microscope users
The PromiseVision 3D™ system contains many innovative elements, identified in the graphic below. The hybrid combination of advanced electronics and high quality optics make possible the New Standard of Care for Endodontists and Microscope Users.
1. Powerful Video Processor
Real-time 3D Vision requires the processing power of 20–50 contemporary PCs to process 10–20 gigabits of video data per second, and the processing must be instantaneous. 3D Vision Systems has developed the first processor design providing this power in such a small, affordable package.
2. Perfect Ergonomic Position
An innovative system configuration always places the 3D monitor and the 3D image in a natural, intuitive position for the dentist. A motorized actuator provides monitor height adjustment, for a perfect ergonomic position and a healthy posture on all operative procedures.
3. Normal Depth Perception
An innovative compact and robust optical system directs images to two HD cameras. Left and right cameras capture the images intended for the left and right eyes–thus eliminating the binocular eyepieces of dental microscopes. The images from the left and right cameras are processed into a 3D image, yielding the depth perception of normal binocular vision.
4. Unprecedented Depth of Field
The optical design also allows a full arch or quadrant to be viewed with 5X+ magnification on the monitor. The optics combined with electronic magnification permit unprecedented depth-of-field.


The eyes of insects and many other arthropods are compound, each composed of up to several thousand individual visual organs called ommatidia. The surface of each ommatidium is a hexagonal lens, below which is a second, conical lens. Light entering the ommatidium is focused by these lenses down a central structure called the rhabdom, where an inverted image forms on light-sensitive retinular cells. Pigment cells surrounding the rhabdom keep light from other ommatidia from entering. Optic nerve fibers transmit information from each rhabdom separately to the brain, where it is combined to form a single image of the outside world.


When choosing new glasses, it is important to choose the right refractive index of the lens. A higher index means that the lenses are thinner even if you wear diopters thicker than +/- 2. Glasses with a higher index will be lighter and will not press you so much on the nose. Thin lenses are much more elegant and look better.
We will explain this with a simple example:
Andrew is short-sighted and needs diopters with a power of -2. Matthew is also short-sighted, but needs stronger diopters, with a power of -5. If Andrew and Matthew choose lenses with the same index, Matthew’s will be much thicker than Andrew’s. In order to craft a lens, there must be more material used and it must therefore be thicker and heavier overall. However, a higher lens index changes everything!
So that even people with higher diopters can have nice-looking glasses with thin lenses, they can be made with a higher refractive index. Compared to a standard lens, they can be much thinner with the same diopter.
Plus lenses for correcting farsightedness or partially sightedness tend to be thickest in the middle, while minus lenses for correcting myopia are thickest at the edges. By choosing a higher index, we do not completely remove the curvature of the lenses, which gives them their shape, because it is necessary for them to have a dioptric effect. However, we can significantly influence how they protrude from the spectacle frame.
Choose the lens index according to the power of the diopter:
- Index 1.5 - lenses of standard thickness with excellent optical quality, ideal for diopters up to +/- 2.
- Index 1.6 AS - 30% thinner lenses with aspherical design, which reduces distortion in the periphery at higher diopters. They have very good optical quality, the material provides 100% UV protection, they are 7 times more durable than 1.5 lenses. This index is ideal for diopters from +/- 2.25 to +/- 4.
- Index 1.67 AS - 40% thinner lenses with aspherical design. They have good optical quality and the material provides 100% UV protection, they are 6 times more durable than a 1.5 lens. This index is ideal for diopters from +/- 4.25 upwards.
Other materials we can find out there:
1.53 trivex - extremely resistant lenses to breakage, suitable e.g. for sport-lovers.
1.59 polycarbonate - ultralight and durable lenses.
1.74 AS - the thinnest aspherical lenses suitable for diopters over +/- 6.
When you choose glasses on eyerim, you have the opportunity to choose from 3 indexes of lenses in the configurator, which are - from our point of view - the best. They are optically high quality and can cover a wide range of diopters.
The higher index of lenses also has its disadvantages:
A higher refractive index means a lower so-called Abbe number, which determines the overall optical quality of vision and light scattering. In the case of lenses with a high refractive index or in the case of polycarbonate lenses, a number of disturbing reflections are also formed in the material, which can be an obstacle, especially in the case of frameless spectacles. Therefore, we prefer not to offer these lenses.
One of the best trade-offs between lens thickness and vision quality is the 1.6 index lens. It can satisfy most wearers who do not have high diopters. At the same time, it also provides high mechanical resistance, which will be appreciated by the wearers of frameless and semi-framed glasses.
No worries, we will help you choose!
It is good that you are interested in the details of purchasing your new glasses. However, so that you do not have stress when choosing the index, we have decided to choose it for you at least with our glasses from the eyerim collection. We will take into consideration your diopter and frame type. Our partners craft thousands of glasses daily in the optical laboratory.
You can really trust our optometrists. We guarantee you not only thin and aesthetic lenses, but also those that will give you the best possible vision.


About DXO Optics Pro 9
DxO make the standard camera sensor testing software, meaning they're a pretty good authority when it comes to photo software. So it's no surprise DxO Optics Pro ($99 direct) is indeed one of the most impressive pieces of photo software out there, and, since my last review of the software, it's made large leaps forward, particularly in improved organization features and program stability. It tops these off with unmatched image processing: DxO claims the new, unique Prime feature gives you a full extra stop of exposure with no increase in noise level. Even without that, Optics Pro can do wonders for your digital photos—particularly if you shoot in camera raw mode.

When looking at security cameras for your surveillance system at your business or home, there are so many options that it can be confusing. Take the confusion out with this S-Series dome camera with Starlight Technology. This 2MP eyeball dome is IP66 rated and is therefore able to be used both inside and outside! No need to be concerned since this works well in rain, snow, wind, humidity and even temperatures ranging from -4°F to +122°F.
The Starlight technology allows the cameras to work in low-lux conditions and produce full color images in the dark even when other cameras have sensed the change in lighting and have switched to monochrome. When not using the Starlight, the built-in LEDs let you see up to 98 feet in total darkness. This S-Series dome uses a 2.8-12mm manual zoom lens that allows you to change the zoom at the camera if you find that your environment changes or you just need to see more detail. You’ll be able to adjust the lens so you can get a wide angled view over a large area or you can zoom in and get a more focused view on people or products.
This S-Series camera is ONVIF compliant so it can be paired with other ONVIF products but will work best with other S-Series products available on our website. You have a choice when it comes to powering your camera. You can use a standard 12V DC power supply (which you might have readily available) or, since this camera is PoE compliant, you can power it using PoE (Power over Ethernet). That’s where you plug the camera into a PoE switch or PoE ready NVR and power is supplied using the CAT5 cable.

Surface plasmon resonance (SPR) and Biacore systems.
Surface plasmon resonance (SPR) is an optical phenomenon used to measure the interaction of biomolecules. Biacore instrumentation utilises surface plasmon resonance to allow biomolecular interaction analysis in real time without the need for labels. Detection and analysis of bimolecular interactions is of considerable interest across a wide range of research fields including academic, biotechnology and pharmaceutical sectors. The ability to measure these interactions is beneficial for a wide range of applications in particular for both diagnostics and therapeutics.
Diagram: Surface plasmon resonance-based biosensor
Surface plasmon resonance occurs when polarised light is passed through a prism and undergoes total internal reflection at a metal surface of a sensor chip and liquid interface. The light energy excites plasmons in the metal surface causing them to oscillate and resonate. As plasmons absorb incident light energy, a decrease in the intensity of the reflected light is observed by the optical detection unit.
Biacore technology exploits this methodology by using a gold sensor chip immobilised with ligand and passing over analyte in solution. As analyte binds to the immobilised ligand a change in mass at the metal surface occurs. This binding interaction perturbs the resonating plasmons and this change is recognised by the optical detection unit as a decrease in the intensity of reflected light. Biacore instrumentation uses this information to produce sensogram graphs which can provide results and data on the biomolecular interactions of a variety of molecules. Data produced by Biacore technology allows the screening and characterisation of binding molecules, determination of kinetic rates and determination of binding affinity.
There is a rich history of antibody-antigen interaction analysis within the BDI including low molecular weight compounds which can be analysed to provide important information for drug discovery and therapeutic development.
