The National Laboratory for Photonics and Quantum Technologies - NLPQT - is a nationwide investment project carried out by a consortium of 7 scientific units led by the University of Warsaw. The main purpose of the project is to create new research infrastructure in three areas:
- Generation and Distribution of Reference Optical Carrier
The main goal of the National System for Generation and Distribution of the Reference Optical Carrier is to construct an ultra-stable laser system that can be linked to an optical atomic clock, along with a distribution network using optical fibers. The optical reference signal with low phase noise will be distributed from Toruń to all of the participants of the NLPQT consortium where it will be available to both interested researchers and industry partners.
- Photonic Technologies
Another aim of the NLPQT project is to build a network of research stations which will either extend the existing or provide completely new research opportunities. The new equipment will be used in a wide variety of applications such as spectroscopic studies of materials (e.g. the analysis of trace air pollutants or characterization of new materials for photovoltaics and medicine), fabrication of specialized optical fibers, development of nano- and microstructures for optoelectronic and medical applications, design, production and characterization of lighting systems, two- and three-dimensional imaging of biological objects and many others.
- Quantum Technologies
In the area of quantum technologies, the NLPQT project is focused on the development of a country-wide infrastructure enabling practical utilization of properties of individual quantum objects. A particular emphasis is put on the possibility of using single photons in quantum communication, which will enable both research and development work on quantum key distribution (QKD) as well as integration of such solutions with other mechanisms used to secure data transmitted over existing IT and telecommunication systems. Furthermore, test workstations utilizing real-life applications of such quantum objects as single electrons, quantum dots, or atoms will also be established.
The infrastructure built within the framework of the NLPQT project will not only serve the scientists directly involved in the project, but will also be available to other researchers and industry partners. For more information visit the website of the Project at http://nlpqt.fuw.edu.pl.

Frequently Asked LED Lighting Questions
Here are a few of our most frequently asked questions. If you don’t find the answer to your questions, please get in touch at 613.723.8528
What does LED stand for?
LED stands for Light Emitting Diode, and as the name suggests, they are diodes – encased in plastic – that emit light. A diode is a simple semi-conductor device that permits current to flow in one direction. Semiconductor diodes are a junction of two materials. One material has a surplus of positive charge, and the other a surplus of negative charge. When a forward voltage is applied, the two are brought together to release light energy – thus are ‘light emitting’,
Is an LED fixture a bulb?
While an LED fixture may appear to be a bulb, it isn’t. As mentioned above, LED’s are tiny semiconductors encapsulated in plastic (which protects their components and helps to focus the light), and typically mounted on a circuit board.
What’s the difference between an incandescent bulb and LED fixture?
Light from an incandescent is created when electricity heats up the filament, causing it to glow and generate heat… which, in turn generates light. The majority of the energy created is wasted heat, not light.
An LED fixture is essentially the opposite, in that light is created through a relatively cool process. When electricity is applied to a semiconductor (usually comprised of the components – gallium, arsenic and phosphorous), they’re stimulated by the movement of electrons, which create photons. Photons are the light visible to us.
Does an LED fixture have a wire filament?
No, an LED fixture operates with completely different components. Because they’re diodes, electricity can only move in one direction. Much like the familiar positive and negative terminals of a battery, the (+) anode is where the current comes in and the (-) cathode is where the current goes out.
Incandescent bulbs are omni-directional in that they project light in every direction, while LED fixtures are designed to project light in specific directions or angles (ex: 20°, 50°, 120°, etc.).
Why do LED fixtures use such little power?
Since an LED fixture doesn’t use a filament that creates light through heating, and produces light with very little heat, they are much more efficient and cost-effective to operate.
Does an LED fixture produce heat?
An LED fixture produces very little heat – and any noticeable heat is usually the result of components on the printed circuit board and not the LED itself – as compared to an incandescent bulb that uses heat to produce light.
Are LED fixtures affected by extreme conditions?
An LED fixture is manufactured to perform in harsh environments and functions well in temperature ranges -40° C to over 80° C… with no delay or warm up time.
Does the light produced by LED fixtures attract insects?
Because most insects perceive entirely different light spectrums and are attracted to ultraviolet light, most can’t perceive the light an LED fixture produces… and so won’t be attracted to it.
How long will an LED fixture last?
LED fixtures are rated by their manufacturers to operate under normal conditions for many, many years.
Why are LED fixtures more expensive than incandescent landscape lighting fixtures?
While a single LED can operate as a standalone device, when grouped or clustered – as they must be in an LED fixture – they need other components, including a circuit board, driving components and a weatherproof housing to endure the elements.
As a result, the cost to manufacture the fixture is somewhat higher then those that house incandescent bulbs. Bit since the LED fixtures use up to 80% less electricity to operate, when amortized over a few years, LED fixtures are quite a bit less expensive, over all, when compared to their incandescent cousins.

Why Is The Sky Blue
“Because that blue sky that we all see is neither sky nor blue. What a shame that such beauty is not real!” These beautiful verses by Lupercio de Argensola are usually quoted as an example of the baroque disappointment for nature’s makeups. It was certainly during the 17th century when the man discovered with astonishment the reason for the color of the sky, that up to then had been believed to be compact and immutable.
The color theory developed by Newton explains that white light is formed by the combination of all the colors of the rainbow.
When we see an object of one color, it is because it reflects a certain wavelength and absorbs the rest, or which is the same thing, it reflects that color while absorbing the others.
At one end of the visible spectrum is red, whose wavelength is longer and therefore the lower frequency; because of this we call waves with a lower frequency “infrared”.
At the other end, violet, whose wavelength is shorter and therefore the highest frequency; therefore we call wavelengths with a higher frequency “ultraviolet”. But the sky, besides light composition, owes its color to another important factor: the atmosphere.
In effect, the light of the sun has to cross the atmosphere in order to reach us, and during that journey it looks altered. Minute particles of dust and water suspended in the air are smaller than the wavelengths of visible light, they do not have enough wave size to repel, but to divert slightly from its original path.
This is known as “dispersion”. And since the wavelengths on the blue end of the spectrum are shorter, they are dispersed to a greater degree than the rest of the colors, and this gives our sky its blue color.
To be exact, we need to add a third factor to determine why we see the sky as blue, and that is our own physiology. It happens so that, being consistent with what we have just said, the sky should be violet wavelengths as this color is still lower than in the blue.
If we see it violet is because our eyes capture the color in their own way, since they have cells sensible to only trhee colors: red, green and blue, and we perceive the rest of the colors by combination, that is, because they excite several of these three kinds of cells at the same time.
Therefore, as our sight is more sensible to the colour blue than to violet, it is that colour we observe when gazing at the sky.

Rectilinear are normal lenses that show straight lines as straight lines. Fisheye Lens The DX-format camera can use both types of lenses (DX and FX) since the non-DX lens image circle is larger than needed on a DX-format camera. On an FX-format camera with a DX lens mounted, the camera will automatically engage its built-in DX crop mode, thus recording an image only from the center section of the sensor The lens features HSM, which is Sigma's version of ultra-sonic drive. Thanks to that, the lens is fully compatible with all current Nikon DSLRs, including the entry-level DX models. Typical for many HSM lenses, the AF is virtually silent and very fast. The Sigma is a G-type lens and thus does not offer an aperture ring Some DX / APS-C lenses are known to work quite well on full-frame cameras, with some vignetting that can be removed in the corners (the Nikon 35mm f/1.8G is a good example of such lens). The Sigma 18-35mm f/1.8G is not a good candidate to be mounted on a full-frame camera, especially at the shortest end of the focal length Best DX standard zoom: Sigma 17-50mm f/2.8 EX DC. The typical DX standard zoom covers a 17-50mm focal length (equivalent 26-75mm), offering a versatile wide-angle to short-telephoto focal length in a single lens.

The Tamron 90mm f/2.8 Di Macro is a great lens, but the Sigma 70mm f/2.8 beats it handily in the sharpness department, particularly in sharpness uniformity at f/2.8. The Sigma also edges out the. After-all, this lens bears the designation of a macro lens so let's talk a little about how it truly performs as such. Dedicated macro lenses produce images with a magnification factor of around 1.0 or 1.1x (meaning the subject is life size on the camera sensor). The Sigma 18-300mm has a maximum magnification factor of 1.3x An advantage held by the Sigma 105mm f/2.8 EX DG OS HSM Macro Lens over many competing lenses with similar focal lengths is that it is compatible with extenders. Sigma's 1.4x and 2x DG extenders to be specific. With the 1.4x mounted, this lens becomes a 147mm f/4 OS lens and it becomes a 210mm f/5.6 OS lens with the 2x behind it It's vital to have a sturdy tripod, especially while shooting with a telephoto lens. There's a lot of weight to a telephoto lens — such as a Sigma 60-600mm Sports. Sometimes you could be shooting at a long exposure and a sturdy tripod will help prevent motion blur. The Right Lens.

Nikon DX/Sigma DC/Tamron Di II/Tokina DX: Denotes a lens that is designed for APS-C DSLR sensors. Use of this lens on a full-frame (FX) sensor will likely cause vignetting. All full-frame Nikon DSLRs are able to detect DX lenses and crop the image accordingly by default. However, the viewfinder view is likely to be constricted Sigma 18-200mm f/3.5-6.3 DC Macro HSM Lens for Sony DSLRs Manufacturer's Description: The smc P-FA Zoom 28mm~105mm f/3.2~f/4.5 AL [IF] standard zoom lens is the perfect standard zoom lens for both beginning and advanced photographers The Sigma 35mm f/1.4 ART lens is more than capable of shooting beautiful portraits and landscapes and at a fraction of the price. Right now, the Nikon 35mm f/1.4 lens is about $1,800 vs. less than $700 for the Sigma. So you're paying almost three times the price for the native Nikon lens In addition, Sigma recently began offering a bundle for their 150-600mm with a 1.4x teleconverter. Since I shoot mainly with a Nikon D750 full frame, the lens bundled with a 1.4x TC interested me very much. The 1.4x TC makes the 600mm, an 840mm on a full frame camera, so in theory this allows my full frame camera to shoot wildlife with nearly.

Scientists have discovered fluorescent frogs
Scientists in Argentina have discovered the world’s first fluorescent frog — by accident.
Researchers at the Buenos Aires Natural Sciences Museum were studying the polka-dot tree frog, which is usually dull, when they noticed that it glowed after they shined ultraviolet light on it.
“We couldn’t believe it,” study co-author Julián Faivovich, a researcher who worked on the project from the University of Buenos Aires, told the journal Nature. “I’m really hoping that other colleagues will be very interested in this phenomenon, and that they will start carrying a UV flashlight to the field,” he said.
Fluorescence is the ability to absorb light at short wavelengths and re-emit it at longer wavelengths. Other animals such as jellyfish, scorpions, and even birds have similar glowing qualities, but it’s “unprecedented” in amphibians, according to the researchers.
The team is still trying to determine whether this quality comes from the frog’s biology or its habitat.


What kind of Teflon mesh belt is needed for UV curing machine
UV curing machine is also known as UV curing furnace. It uses high temperature ultraviolet light to cure the resin. Due to the characteristics of ultraviolet light, the brown Teflon mesh belt often turns into white after the use, and the surface is coated with Teflon. The layer will also gradually decompose and produce harmful substances, so the brown Teflon mesh belt cannot be used.
In response to the characteristics of ultraviolet light, Taixing Kaipeng added black pigment to resist ultraviolet rays when it was used to produce Teflon mesh belt. Antistatic material was added to prevent static electricity, and the anti-ultraviolet effect was remarkable. The antistatic coefficient was uniform and stable, and the effect was good.
Therefore, UV UV curing machines generally use black Teflon mesh belts.

Can Binoculars Damage Your Eyes?
Binoculars are a great tool for bird watching, stargazing, and other activities that require long-range vision. But can they damage your eyes? The short answer is yes, binoculars can damage your eyes if you use them improperly. This article explains about how binoculars damage your eyes that can be used as references when want to know about binoculars.
Best crossbow in the market is BARNETT Whitetail Hunter STR Crossbow, Mossy Oak Bottomland, Standard 4×32 Scope
Best recurve bow in the market is Southwest Archery Spyder XL Recurve Bow
The risk of eye damage increases when you use higher magnifications, so it’s important to be aware of the potential risks before you start using binoculars.
There is a lot of debate on whether or not binoculars can damage your eyes. Some people say that they can, while others claim that they cannot. So, what is the truth?
Can binoculars actually harm your vision? The short answer is yes, binoculars can damage your eyes if you use them improperly. However, if you use them correctly and take proper precautions, then they will not cause any harm to your eyesight.
Here are some tips to follow if you want to avoid damaging your eyes when using binoculars: -Make sure that the lenses are clean before using them. Dirty lenses can magnify the sun’s rays and damage your retina.
-Wear sunglasses when using binoculars in bright sunlight. This will help protect your eyes from the harmful UV rays. -Do not look at the sun directly through the binoculars.
The intense light can damage your retina permanently.
Can binoculars damage your eyes? | Optics Trade Debates
How Close to Your Eyes Should You Hold Binoculars?
Assuming you are holding binoculars up to your eyes, the lenses should be about one inch from your eyeballs. If the lenses are too close or too far away, it will be difficult to see anything through them.
Do You Need to Wear Glasses When Using Binoculars?
Assuming you are referring to corrective lenses:
Yes, if you wear glasses you will need to wear them when using binoculars. This is because the eyepieces in binoculars are fixed and cannot be adjusted to accommodate for different vision needs.
So, if you have poor vision and normally wear contacts or glasses, you will need to keep wearing them when using binoculars. There are some workarounds that people with glasses have used in order to still be able to use binoculars without having to constantly take their glasses on and off. One solution is called the Diopter Adjustment Knob which can be found on most binoculars.
This knob adjusts one side of the lens slightly differently than the other in order to help people with varying degrees of vision discrepancies between their left and right eye. Another workaround is wearing contact lenses instead of glasses when using binoculars. This option might not work for everyone though since it takes a bit of time for your eyes to adjust when switching from corrective lenses to none at all.
Is Eye Relief Important in Binoculars?
Yes, eye relief is important in binoculars. Here’s why:
When you look through binoculars, your eyes need to be a certain distance away from the lenses in order to see the full field of view.
This distance is called the “eye relief.” If the eye relief is too short, you’ll have to move your head closer to the binoculars in order to see the full image, and this can be uncomfortable. On the other hand, if the eye relief is too long, you’ll see black circles around the edges of the image (these are called “vignetting”).
The ideal eye relief for most people is between 15mm and 20mm.
Does Looking at Electronics Damage Your Eyes?
It’s no secret that staring at screens all day can be tough on your eyes. But just how bad is it, really? We talked to an expert to find out if using electronic devices is actually damaging our peepers.
Here’s what we found out: While there isn’t enough evidence to say that looking at screens definitely causes long-term damage to your eyesight, there are some potential risks associated with extended screen time. These include: Eye fatigue: When you stare at a screen for hours on end, your eyes can become fatigued, causing dryness, redness and irritation.
If you experience these symptoms frequently, you may have something called computer vision syndrome (CVS). CVS is a temporary condition that can be alleviated by taking breaks from screens and practicing good eye hygiene (more on that below). Blurred vision: prolonged screen time can also cause blurred vision.
This is because the eye muscles can become strained from constantly adjusting the focus from near objects (like screens) to faraway objects (like the rest of the room). If you find yourself squinting or rubbing your eyes frequently when using electronics, it’s probably time to take a break. Dry eye: Staring at screens can lead to dry eye because it decreases blink rate.
blinking helps spread tears over the surface of the eye, keeping them lubricated. When you don’t blink as often, your tears can evaporate too quickly, leading to inflammation and discomfort. To combat this problem, try the 20-20-20 rule: Every 20 minutes, take a 20-second break and look at something 20 feet away.
Binocular Vision Dysfunction
Binocular vision is the ability to see an object with both eyes at the same time. The brain uses the information from both eyes to produce a single, three-dimensional image of the world around us.
People with binocular vision dysfunction (BVD) have trouble seeing objects in 3D.
They may see two images instead of one, or their brain may have difficulty combining the information from both eyes into a single image. As a result, people with BVD often experience headaches, eyestrain, and fatigue. There is no cure for BVD, but glasses or contact lenses can help some people by correcting any refractive error that may be contributing to the problem.
In some cases, prismatic lenses can be used to realign the images seen by each eye. However, these treatments only provide temporary relief and do not address the underlying cause of BVD. If you think you might have BVD, make an appointment with your eye doctor for a comprehensive exam.
Binoculars near Me
If you live in or near a big city, chances are there are several places to buy binoculars. However, if you don’t live near a big city, or if you’re looking for a specific type of binocular, it can be tricky to find what you’re looking for. Here are a few tips on where to look for binoculars:
– Online retailers: There are many online retailers that sell binoculars. If you know what type of binocular you’re looking for, this can be a great option. You’ll often find better prices online than you would in brick-and-mortar stores.
– Local sporting goods stores: Many sporting goods stores sell binoculars. This is especially true if the store specializes in hunting or fishing gear. – Online classifieds: Sites like Craigslist and eBay can be great places to find used or vintage binoculars.
Just be sure to check the seller’s feedback before buying anything!
Best Binoculars for the Money
We all know how important it is to have a good pair of binoculars. Whether you’re an avid birdwatcher, hunter, or nature lover, having a quality pair of binoculars can make all the difference in your outdoor experience. But with so many different brands and models on the market, it can be hard to decide which ones are right for you.
That’s why we’ve put together this guide to help you find the best binoculars for the money. There are a few things you’ll want to keep in mind when shopping for binoculars. First, consider what you’ll be using them for most often.
If you’re primarily interested in birdwatching, then you’ll want to look for a pair that has good light gathering capabilities and produces clear images. For hunters and other outdoor enthusiasts, durability and low-light performance may be more important than image quality. Another thing to think about is magnification power.
Most binoculars have somewhere between 7x and 10x magnification, but if you know you’ll be doing a lot of long-distance viewing, then you might want to opt for a higher power pair. Just remember that higher magnifications also tend to produce shakier images, so they’re not always ideal for everyday use. Finally, don’t forget to factor in price when making your decision.
Binoculars can range from less than $100 to several thousand dollars, so it’s important to find something that fits your budget. Luckily, there are plenty of great options at every price point. Now that you know what to look for, we hope our guide helps you find the best binoculars for the money!
No, binoculars cannot damage your eyes. However, if you stare at the sun through binoculars for an extended period of time, you could damage your eyesight.

• Optical Bonding has a lower cost than most other competing technologies.
• Optical Bonding offers superior ruggedization, enhancing the display durability under vibration, shock and other environmental extremes.
Optical Bonding Technology
Understanding and controlling reflected light will dramatically improve the performance of a display in any ambient lighting condition. Sunlight view-ability of a display depends on the differences between “lumination” and “illumination” of the display. The lumination of the display is its brightness. A display’s brightness, typically referred to as a Nit (Candela per meter/2) is the amount of light energy coming out of the display. Illumination is the amount of ambient light shining onto a display.
This combination reduces the total reflection of the display and front cover glass to less than 2% of the ambient light.
At 500-800 nits brightness, most displays will be completely sunlight viewable.
Anti-Reflection & Anti-Glare Protection Glass Coating Technology:
The anti-reflective coatings on the protection glass have excellent performance in tough ambient light conditions.
• Anti-reflective (AR) coated protection glass can minimize mirror image and maximize transmittance
• Anti-glare (AG) coated protection glass can scatter light directed on the surface and soften the image of direct light sources visible in the reflection of the viewing area
• With two side AR and one side AG coated glass are suggested to provide the best visibility Applications
• Exhibition Signage
• Outdoor Kiosks
• Public Information POS
Products use this technology
These coating glass solutions we provided at i-Tech Technology, are now available for full range displays from 6.4″ to 37″ By customized request.

Summer time is approaching…now is the time many people working outdoors break out the sunglasses. While conventional sunglasses may protect the eyes from glare, they do a poor job of protecting your eyes from the industrial hazards of splashes, flying objects, and dust. In fact, conventional glasses can present their own hazards in the workplace.
- It is a fact that the frame and lenses used in safety glasses are stronger than the frame and lenses used in conventional glasses. When an object strikes the lens of safety glasses it is very unlikely that the lens would dislodge. This is not true of conventional eye wear, especially those types with wire frames. When an object strikes the lens of conventional glasses, the lens can shatter, showering the wearer’s eye with shards of glass. This can happen, and it has happened. But, with a pair of approved safety glasses, the lens may break, but it will not shatter back into the eye.
- Safety glasses also have shields to reduce the risk of foreign objects reaching the eye from the sides, top or bottom. Sunglasses do not.
- Because sunglasses have a darkened lens, some people mistakenly believe these glasses will provide the needed protection when welding, brazing, or cutting. This is far from the truth. A darkened lens will not protect your eyes from the infrared (IR) and ultra-violet (UV) radiation. Wearing glasses with darkened lenses which are not made for industrial applications, can actually be more dangerous than wearing no glasses at all. For adequate protection from the visible light produced by welding, the lens must be of a specified shade. Sunglasses are not welding/cutting goggles.
- What should you look for when selecting safety sunglasses? First, be sure the glasses are indeed safety eye wear, by checking to see if they comply with American National Standards Institute (ANSI) standards, the organization which sets the criteria for safety eye wear. This will be stated on the packaging and on the frame of the glasses. Look for “Z87.1.” This is the ANSI designation identifying the glasses as approved safety eye wear.
Although not a necessity, consider glasses providing IR and UV protection. Look for glasses that are lightweight and adjustable. If the glasses don’t fit properly, they won’t be comfortable and thus they may not be worn. Try them on and adjust them before starting work. Get with your supervisor or safety tech if you are in need of a pair of safety sunglasses.

Lens treatments include:
- Non-glare treatment by Crizal ®
- UV protection
More on UV protection – UV light is absorbed by molecules known as chromophores, which are present in the eye cells and tissues. Chromophores absorb light energy from the various wavelengths at different rates – a pattern known as absorption spectrum. If too much UV light is absorbed, eye structures such as the cornea, the lens and the retina can be damaged causing cataracts, macular degeneration and pinguecula among other things.
Protective eyewear is beneficial to those who are ever exposed to sunlight. Given that light may reach the eye from the sides, full coverage eye protection is usually warranted if there is an increased risk of exposure, as in high altitude mountaineering. Mountaineers are exposed to higher than ordinary levels of UV radiation, both because there is less atmospheric filtering and because of reflection from snow and ice.
Ordinary, untreated eyeglasses give some protection. Most plastic lenses give more protection than glass lenses, because glass is transparent to UVA and the common acrylic plastic used for lenses is less so. Some plastic lens materials, such as polycarbonate and high index, inherently block most UV. There are protective treatments available for eyeglass lenses which will give better protection.


The ZScanner 700
The first portable laser scanner.
This state-of-the-art laser scanner helps engineers improve design and inspection throughout the manufacturing process. Connected to a laptop via a single FireWire cable, setup is quick and scanning objects is easy, fast, and accurate.
For a demo movie click here
The ZScanner® is the first self-positioning scanner on the market. This digital scanner uses the subject part being scanned to establish its spatial reference.
No external tracking or positioning device is needed
The handheld ZScanner does not need an external tracking device like a CMM or measuring arm to establish its location or reference in relation to the object.
Innovative Positioning Targets and Setup
To position itself, the ZScanner uses reflective targets, which are applied to the surface of the part to be scanned and/or the area adjacent to the part. These reflective targets can be quickly and randomly applied. The only other setup involves connecting a Fire Wire cable to the computer, which takes only seconds.
Flexibility of Movement (Free-flowing Movement)
The use of reflective targets allows end users to freely move the object or scanner or both while scanning without losing track of the scanner’s position in reference to the part. This advantage comes in handy for engineers scanning cars or large objects. Since the ZScanner positions itself in reference to the object being scanned, engineers can get in and out of the car to collect all the data they need. The targets are attached to the car’s surface so movements do not affect data quality. It is possible to either scan with the doors open for easy access and to keep all parts or components in the same reference or with the doors closed to compile additional data for ergonomic analysis.
The Technology behind It
During the scanning process, the ZScanner locates and captures the reflective positioning targets in real time. Their respective positions are calculated in reference to the scanner and then recorded. The targets on the object create patterns recognizable by the ZScanner. The patterns defined by the positioning features do not repeat because the targets are applied randomly. This pattern recognition allows the scanner to position itself in the same way that GPS devices use known satellites to establish their position on Earth.

My team and I were fortunate enough to be one of the drone teams to pose as “picture drones,” in the feature film Venom (2018). Sony needed two drones to carry bright LED rigs to pose as autonomous drones throughout a scene involving a spaceship crash-site. Our job was to have our drone look cool on screen as well as supply some dynamic lighting. Mission accomplished!
Our team assembled a 9 light LED array which produces 126,000 lumens. The rig sits in one of our gimbals. This allows the light rig to be stable in the air as well as point-able. This allows us to remotely strike the LED rig on and off, as well as pan and tilt the light in the direction we need to point the light. The system really worked well!
LED aerial rigs are becoming more and more popular on set. The flexibility and versatility continues to increase all the time it seems.
If you need a LED aerial rig for your next production, you can contact us directly.


In what is said to be an unprecedented deal, China has sold Pakistan a powerful tracking system that could speed up its military’s development of multi-warhead missiles, the South China Morning Post reported on Thursday.
Chinese authorities confirmed the technology transfer on Wednesday. A statement on the Chinese Academy of Sciences (CAS) website said China was the first country to export such sensitive equipment to Pakistan.
The CAS said a Chinese team spent three months in Pakistan helping calibrate the system. “The system’s performance surpassed the user’s expectations,” it said, adding that it was considerably more complex than Pakistan’s home-made systems.
Zheng Mengwei, a researcher with the CAS Institute of Optics and Electronics in Chengdu, Sichuan province, also told the Hong Kong-based newspaper that Pakistan had bought a highly sophisticated, large-scale optical tracking and measurement system from China.
The Pakistani military recently deployed the Chinese-made system “at a firing range” for use in testing and developing its new missiles, he said.
According to the newspaper, an optical system is a critical component in missile testing. It usually comes with a pair of high-performance telescopes equipped with a laser ranger, high-speed camera, infrared detector and a centralised computer system that automatically captures and follows moving targets.
The device records high-resolution images of a missile’s departure from its launcher, stage separation, tail flame and, after the missile re-enters atmosphere, the trajectory of the warheads it releases.
The uniqueness of the Chinese-made system lay in its use of four telescope units, “more than normally required”, Zheng told the newspaper.


"A hand-held telescope with well-turned granadilla case", says the inventory of 1746.
The tube of this classical Galilean-type small telescope is of glued pasteboard, made from waste-paper. The outside, green, has a gilded flower pattern.
The optical system is one of the more simple, comprising two lenses, one convergent (object lens), the other divergent (eye-piece). The image is thus virtual, straight and magnified. Only the object lens remains.

Laser cutting is a gold standard when it comes to high-quality fabrication services across industries. This advanced technology creates complex design patterns by cutting into materials including metals, plastic, glass, wood, and many more. From melting, burning, engraving, or vaporizing the material — laser cutting is the ultimate method.
This technology utilizes a powerful, focused laser beam to cut the material blocks into bespoke patterns and shapes. It is a high-power thermal-based fabrication process that has become a ‘must-have method’ in several industries. On this note, let’s sneak peek into fun and interesting facts about laser cutting technology:
It’s half-a-decade old technology
Laser cutting services sound like modern advancement, but it’s been around us for more than five decades. In the mid-1960, scientists from the Western Electric Engineering Research Center created the first laser cutting machine, which the technicians used to cut diamonds.
Some machines can perform welding
For catering to advanced laser cutting service, some machines are also capable of performing welding. Depending on the specific style, a laser cutting machine may also perform welding processes. Mainly, there are three types of setups available — CO2, Nd, and ND:YAG.
Among these two, the ND:YAG and CO2 laser cutting machines can do the welding process. Nd type of laser machine is not able to perform any welding work. However, the Nd machines are suitable for tasks that require minimal repetition.
It can achieve focus up to 0.001 inches
Another performance-driven fact about laser cutting is that it offers much higher cutting accuracy and surface finishing as compared to other methods. Laser cutting machines can focus the powerful laser beam to the surface area with a diameter of only 0.001. With such accurate laser focus, the beam can focus on very tight spaces with higher precision. Using a powerful laser beam, manufacturers can achieve high-quality cutting and excellent surface finish.
Laser cutting supports more than 25K applications
As Industry 4.0 is on the verge of disruption, industries are using laser cutting technology to accomplish thousands of jobs. There are more than 25,000 high-power laser cutting applications that enterprises are leveraging to perform bespoke jobs. With laser machines, companies can cut a wide range of materials, including wood, fabrics, paper, acrylic, metals, and many more.
Several companies are offering professional laser cutting in Melbourne, Brisbane, and other places to uplift the overall fabrication process.
It’s environmentally safe
As compared to other fabrication processes, laser cutting is a safer and environmentally sustainable technique. Technicians can efficiently operate this machine without any specialized training. As the material wastage is lower and it decreases the harmful gases, laser-cutting is highly eco-friendly. While the equipment performs operations, the technician controls it from a remote location, improving overall safety.
Laser cutting demands high power
Laser cutting machines are high-power-driven setups that constantly need substantial electric power to execute the jobs. However, the power consumption varies based on the complexity and duration of the fabrication job. The power efficiency of these machines lies between 5% to 45%. From a laser cut of aluminium to paper, or wood, the machines’ laser power varies and directly impacts energy utilization.
Some machines use gas
There is some particular machine type, including melt and blow, that leverages gas to cut through the material. In this process, the laser warms up the material block, and the pressurized gas facilitates the entire cutting operations. This cutting machine delivers smoother fabrication with different types of materials. Methods like melt and blow are ideal for cutting holes into hard and soft metal blocks, including titanium, stainless steel, and aluminium.
Laser’s intensity matters
The laser cutting method’s best part is that it’s highly customizable as per the material and the thickness. To cut through a thicker block of metal, technicians will need a high-intensity laser. Similarly, on the other side, to cut metal sheets, a low-intensity laser is ideal. The laser intensity is measured with the unit of power, for example, 1,000 watts. The intensity is calculated by dividing the total energy by the surface area over which the laser is equally distributed.
Several companies offer a wide range of laser cutting in Brisbane and other cities to boost the manufacturing process. Laser cutting is ideal for both small-batch and mass manufacturing.
Advantages of laser cutting
Manufacturing industries leverage laser cutting services as it comes with substantial benefits across the entire product lifecycle. Some of the compelling applications of laser cutting are:
- Highly accurate and precise
- It offers a faster turn-around time
- Laser is relatively cost-effective as compared to other processes
- It offers a comprehensive material compatibility
- Safer to operate
These were the top interesting facts about the robust laser-cutting technology. If you are looking for professional laser cutting in Sydney, Melbourne, or Brisbane, Zeal has got you covered. Get in touch with Zeal to know more about our laser cutting fabrication services.


Q: I donít like wearing glasses or contact lenses but donít want to have laser surgery. Do I have any other options?
A: Yes. While refractive laser surgery (i.e. LASIK) is a relatively safe procedure for certain patients, many people are hesitant to commit to a surgery that permanently changes the anatomical structure of their eyes. Fortunately, there is a procedure available that is completely reversible at a fraction of the cost of LASIK. It is called CRT (Corneal Refractive Therapy) and consists of being fit with a pair of rigid contact lenses that are designed to be slept in. The lenses temporarily reshape the cornea while you are sleeping so that when you awake and take the lenses out the vision is clearÖ kind of like retainers worn to straighten teeth. The effect typically lasts for 12-36 hours, depending on the amount of prescription being corrected; the lenses are worn only at night and are generally well tolerated. CRT is FDA approved to treat myopia (nearsightedness) and astigmatism. It is a great option for those patients that want to enjoy clear distance vision during the day without the hindrance of glasses or contact lenses but donít want to go to the lengths of a permanent surgery.

Effects of Light Pollution
Light pollution—whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design, which allows artificial light to shine outward and upward into the sky, where it's not wanted, instead of focusing it downward, where it is. Ill-designed lighting washes out the darkness of night and radically alters the light levels—and light rhythms—to which many forms of life, including ourselves, have adapted. Wherever human light spills into the natural world, some aspect of life—migration, reproduction, feeding—is affected.

Researchers develop 3D movie screen that doesn't need glasses
A team at MIT has created technology that would allow for mass-market 3D consumption without the need for glasses
A movie screen that can show 3D films without the need for glasses has been developed by researchers at MIT.
Called Cinema 3D, the technology utilises multiple parallax barriers, rather than just the one used for regular 3D viewing. It allows for different viewers to have the same experience, no matter where they are sitting.
“Existing approaches to glasses-free 3D require screens whose resolution requirements are so enormous that they are completely impractical,” said MIT professor Wojciech Matusik. “This is the first technical approach that allows for glasses-free 3D on a large scale.”
The screen isn’t market-ready as yet but it’s a major breakthrough, given that all previous attempts to take glasses out of the equation were limited to TVs. What’s also important is that this new form of viewing will improve the picture quality.
“It remains to be seen whether the approach is financially feasible enough to scale up to a full-blown theater,” said Matusik. “But we are optimistic that this is an important next step in developing glasses-free 3D for large spaces like movie theaters and auditoriums.”


The non-profit community health center, Clinicas de Salud del Pueblo, is now offering hi-tech health services in communities of rural Riverside County.
A digital retinal camera was installed at their Mecca Clinic Friday to help screen patients for eye disease linked with diabetes and other conditions.
The digital images taken by the retinal camera will be sent to optometrists at the University of California, Berkeley via a secure web portal. Results will be returned to physicians at the Mecca Clinic within 48 hours where early signs of eye diseases linked to diabetes can be identified.
This video by Dr. Bertalan Mesko talks about a number of technologies for diabetes management:
Google X lab is developing a smart contact lens that can measure glucose levels in tears using a small wireless chip and glucose sensor that are embedded between two layers of soft contact lens material. Professor Sae Kwang Hahn and his colleagues at Pohang University of Science and Technology in Korea have made a smart contact lens and eyeglass combination that could be used to monitor diabetes and dispense drugs on-demand. When tear glucose levels rise, the smart contact lens relay this information wirelessly to the eyeglasses, which light up in case of abnormally high sugar levels.
The Tellspec Food Sensor is a handheld device that can scan food at a molecular level. The three-part system–a pocket-sized spectrometer, a cloud-based analysis engine, and a mobile app–work together to scan foods and identify calories, macronutrients, and allergens.
Dario has developed a Smart Meter that lets you test blood glucose levels in seconds, directly on your smartphone. It also has a smartphone app that helps you track, monitor and manage diabetes.
mySugr also has a number of apps to help with diabetes management For example, mySugr Scanner uses an iPhone camera to grab blood glucose values from a variety of existing meters and instantly send blood glucose readings from the meter into mySugr Logbook.


The First FDA-Approved Trifocal Intraocular Lens implanted by ophthalmologist Jason D. Bullajian, MD.
Frisco, TX, September 4, 2019 – The first intraocular lens implant that provides an exceptional combination of near, intermediate and distance vision received FDA approval August 27, 2019, and Dr. Jason D. Bullajian, founder of Texas Vision & Laser Center performed one of the first implantation of the device on a patient in the Dallas Metroplex on September 4th.
“I’ve been performing eye surgery since 2000, and this is an amazing breakthrough. In general, the human eye has a range of vision that includes, near, medium and far distances. Before last week, cataract surgery and lens replacement patients who selected a basic lens, had to choose whether the lens I implanted would correct near or far vision. Then they would wear glasses to correct the other distances. If they upgraded to a multifocal lens they could choose to have two distances corrected, but again, that usually meant wearing glasses to correct the third distance. Now, we finally have a lens implant option that can achieve the uninterrupted vision that tri-focal glasses can provide.”
The FDA approval of PanOptix was based on a pivotal study at 12 investigational sites in the U.S. With this single trifocal lens design, PanOptix patients demonstrated exceptional, uninterrupted vision. The results also showed high patient satisfaction with more than ninety-nine percent of PanOptix patients saying they would choose the same lens again.1
According to the manufacturer of the lens, Alcon, more than 4 million cataract surgeries are performed each year in the U.S., which is projected to increase by more than 16 percent by the end of 2024, and the nearsighted- (presbyopia-) correcting IOL market is expected to grow 60 percent by the end of 2024.
Bullajian continues, “The short 10-15 minute lens implant procedure has always been life changing, but the availability of the new AcrySof® IQ PanOptix® Trifocal intraocular lens is a game-changer, and I’m thrilled to be one of the first ophthalmologist in the Dallas area to be trained and perform implantation of this very promising lens.”

The AcrySof® IQ PanOptix® Trifocal IOL is a type of multifocal IOL used to focus images clearly onto the back of your eye (retina) to allow clear vision after the cataract removal. In addition, the center of the AcrySof® IQ PanOptix® Trifocal IOL allows for better near (reading) vision and intermediate (computer work) vision versus what a monofocal lens would provide.

Infrared light or thermography is the use of an infrared imaging and measurement camera to “see” and “measure” thermal energy emitted from an object. Thermal, or infrared energy, is light that is not visible because its wavelength is too long to be detected by the human eye; it’s the part of the electromagnetic spectrum that we perceive as heat. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared.
What is Infrared?
Thermography and Infrared Light
The higher the object’s temperature, the greater the IR radiation emitted. Infrared allows us to see what our eyes cannot. Infrared thermography cameras produce images of invisible infrared or “heat” radiation and provide precise non-contact temperature measurement capabilities. Nearly everything gets hot before it fails, making infrared cameras extremely cost-effective, valuable diagnostic tools in many diverse applications. And as industry strives to improve manufacturing efficiencies, manage energy, improve product quality, and enhance worker safety, new applications for infrared cameras continually emerge.

Raman Instrumentation for Confocal Raman Microscopy
- 1.5k Downloads
Raman spectroscopy is a weak scattering technique in which typically less than one in a million excitation photons give rise to a single Raman photon. The situation is even more difficult in confocal Raman microscopy, as the detection volume is reduced by the small pinhole and thousands of spectra must be collected in a short period of time. Therefore, careful design of the excitation and detection optics, as well as the appropriate choice of spectrometer and detector is important for successful experiments. As detectors and instrumentation in this field continue to quickly evolve, a snap-shot of state of the art Raman equipment and instrumentation will be provided.


Light screening coneBy Cults on June 26, 2019 16:04
As part of the research of the [ChIP lab](http://chiplab.chem.polimi.it) on Luminescent Solar Concentrators (LSCs), we needed something to improve our measurements. Indeed, light from the solar simulator was coming directly to the optical fiber, without passing through the LSC. We hence needed something to cover both the edge of the LSC and the cosine corrector to which the optical fiber is linked. These two 3D-printed cones, designed by [Andrea](https://www.thingiverse.com/andremaker/about), answered our problems.
