Myths about Polarised lenses.
Here we have some more information about some common myths connected to polarised lenses. The reason we have included all this content is mainly because our wooden sunglasses are protected with Polarised lenses throughout our range. Giving only the best vision in all light conditions.
Myth: Polarised Glasses Fully Block Glare
The concepts of glare and polarisation are complicated, as are the interactions between the two. Normal light moves on many planes. When light waves bounce off of a reflective surface, however, they become polarised. Polarised light moves mostly along one plane. A polarised filter most effectively blocks light that is polarised at a 90-degree angle with respect to the axis of the filter. More light is reflected and therefore polarised horizontally rather than vertically. Therefore, polarized sunglasses are vertically polarized. This drastically reduces horizontal glare. However, the interrelationships between types of glare, polarisation of both the glare and the filter, and the angle of the sun mean that polarized sunglasses will not effectively block all glare at all times. Polarised sunglasses do maintain the traditional features of sunglasses. While your polarised glasses may not perform their polarisation duties perfectly at all times, they will cut the brightness of ambient light. Polarised glasses cut the intensity of light by at least half. As with normal sunglasses, you can choose the level of darkness that you would like.
Myth: Polarised Glasses Are Expensive So They Must Be Good
Actually, price is no guarantee of quality.
Many very expensive polarised sunglasses do not meet industry standards for UV protection. Likewise, many inexpensive sunglasses are polarised and meet or exceed industry standards. Be sure to read the UV protection label on any sunglasses you are considering to see if the glasses are in compliance.UV protection blocks dangerous ultraviolet light from reaching your eyes. Both UV-A and UV-B rays are harmful to the eyes as well as skin. Polarization does not block UV rays. A separate material must be added to polarized glasses to absorb the harmful radiation.You will also need to ensure that the glasses you are considering are truly polarised. Many sunglasses have a test tag that you can use. Look through the glasses at the test tag, and then rotate the lenses 90 degrees. You should notice a significant darkening effect. If there is no test tag, look through two pairs of polarised glasses while rotating one pair 90 degrees. You should see an obvious blocking of light. Of course, most glasses are as advertised; but when paying extra for a particularly feature, it is good to be sure. All SHAYDZ sunglasses lenses are fully UV-A and UV-B protected.
Myth: Polarised Glasses Help In Driving
This myth is basically true, depending on the angle of the sun. On bright, sunny days, the sun’s light reflects off the shiny metal of cars. Light also reflects off of the asphalt of many road surfaces. Polarised glasses can block some of the reflected light, reducing dangerous glare and making driving safer.
Myth: Polarised Sunglasses Make it Difficult to See LCD displays.
This myth is completely true. When the display is viewed from certain angles, it may actually disappear. This has to do with the nature of the liquid crystal display (LCD). The light is polarised in such a way that the polarized glasses can make it disappear entirely. Always remove your polarised glasses before using an ATM or other LCD display.
Myth: Polarised Sunglasses Allow Boaters to See Through Water.
Due to the nature of water’s reflection of light, polarised lenses can make it easier to see underwater objects. The polarizing filter is vertical, while most of the reflected light of the water’s surface is horizontally polarised. The polarised glasses, therefore, can dramatically reduce glare from the water.Additionally, polarised glasses cut the reflected light from other objects such as rocks. The light below the water’s surface is polarised vertically, so the vertically polarized glasses make the water appear darker. However, the lack of reflected light makes the water seem more transparent. Of course, the angle of the sun affects the amount of light that is polarized, thus affecting the ability to see more clearly. Polaried glasses are a widely popular option in today’s market. Polarised glasses are able to reduce glare and improve vision in bright conditions. However, like any other product, polarised glasses have their advantages and disadvantages. Take the time to become educated about the way polarised sunglasses work. By being an informed consumer, you will be able to decide whether polarised glasses are right for you.


Featuring a high contrast Green Emerald PHANTOM lens with a tint that changes with the light from cat.1 to cat.3, the Bollé Nevada PHANTOM gives superior optical clarity and enhanced vision whatever the conditions. This cylindrical frameless goggle is a big hit with Team Bollé athletes including Dave Ryding.
We love the look of this goggle and the addition of the PHANTOM lens provides an impeccable visual experience. This is a goggle packed with high tech features, making it the perfect combination of style and performance.
The Nevada Phantom lens have a double lens, which creates a thermal barrier between the cold-dry air outside on the mountain and the moisture inside the goggle. This prevents the formation of pesky condensation, while an anti-fog treatment is also in action to ensure no fogging either. Flow-tech venting promotes directional airflow across the inner lens, which further reduces the potential build up of moisture.
On the outside of the lens, Carbo-Glas Anti-Scratch technology means you can be safe in the knowledge that your lenses are highly protected, reducing scratching and keeping your visuals crystal clear.
Of course, the lenses also contain Bollé’s high levels of UVA/UVB protection, blocking rays up to 400 nanometers.

Eye Surgical procedure has actually become a mainstream method of vision modification, as well as this write-up will discuss the benefits and also negative aspects of three various techniques being offered to the medical consumer.
Lasik Eye Surgical treatment
LASIK is the phrase for Laser-Assisted Sitting Keratomileusis and is an eye medical system which permanently deals with vision by removing a slim layer of the cornea. This treatment works best on clients with moderate to high levels of nearsightedness (nearsightedness), reduced to modest levels of hyperopia (farsightedness) and also astigmatism connected with nearsightedness, as well as who have thick corneas. It is one of the most popular medical vision improvement approach.
People with regular eye sight see items clearly since photos are brought right into a correct focal point by the cornea and also lens of the eye. Ideally, the cornea's curvature is equally matched to its size in a normal eye. People with astigmatism, nearsightedness or hyperopia have actually off-and-on shaped corneas, so the items seen are not focused effectively. LASIK changes corneal form by exact elimination of corneal tissue, as well as by doing so remedies the eyes' focusing power.
There are, however, risks to LASIK eye surgical treatment.
There is a remote possibility of complete loss of vision. If this happens, it is normally because the individual had a pre-existing problem which should have precluded the surgical treatment to begin with, such as maternity, cataracts, joint inflammation, diabetic issues, glaucoma, or lupus. People with big students are likewise inadequate prospects for LASIK. Dry eye disorder will certainly be aggravated by this procedure.
A few patients whine that they permanently see "ghost" photos, have actually blurred vision, lessened comparison as well as poor evening vision. When LASIK wased initially presented, 5% of clients had post-operative complaints; nevertheless, refinements in the treatment have triggered this price to drop to less compared to 1% if LASIK is executed by experienced practitioners as well as individuals are appropriately screened prior to surgical procedure. If troubles do occur, they can typically be resoved by a retreatment.
FDA has actually authorized LASIK laser eye surgery since 1998. While there are a lot of satisfied clients, there are nevertheless no long term research studies about its effects. Understand the limitations as well as the risks of LASIK eye surgery before you sigh for the procedure.
Though much less well known, these tiny implants can improve vision in individuals with mild to modest myopia without the risk of long-term eye damages fundamental click over here now in the cells removal technique of LASIK. Intacs are semi-circular disks dental implanted in the cornea which extend it to presume a flatter shape. Though somewhat much less exact compared to LASIK, they are removeable and replaceable, so if the person has an unforeseen over- or under-correction, the implant could be gotten rid of as well as one more of a various size placed to get the preferred correction. The implants lie at the edge of the cornea, so the main visual area is completely intact and intact, and also the stamina of the cornea is undiminished, making it a better alternative for pilots and those who take part in get in touch with sports where eye injury is a possibility.
Intacs are unsuitable for serious myopia and more than minor astigmatism (1.00 diopters), as the cornea can just be extended up until now. If the Intacs are gotten rid of, vision returns to its preoperative level. Besides vision modification, Intacs are likewise utilized to deal with keratoconus.
Intacs are FDA accepted as well as One Decade researches have revealed no major problems with Intacs as well as very few patient complaints; however, since the procedure takes a lot more training compared to LASIK, there are fewer eye surgical treatment centers supplying it. However, the Intacs web site provides a checklist of practitioners in each state, as well a few in Canada, Europe as well as Mexico.
Since many people do not want to visit our website run the risk of LASIK as well as Intacs could not aid those with extreme vision troubles, intraocular lens implants (IOL) are a brand-new option accepted by the FDA in 2004 to correct moderate to extreme nearsightedness. The Artisan lens, manufactured by Ophtec, is similar to the type of lens implant used to restore vision adhering to cataract eye surgery.
The brand-new IOL, called the Artisan, is intended for just clients who have 2.5 diopters or less of astigmatism.
The fabricated lens does not change the all-natural lens, but is inserted in front of it. The major problem found with the implant was the constant loss of endothelial cells in the corneas of people who received the implants. The endothelium is a layer of cells that line the undersurface of the cornea and also are crucial in maintaining the cornea clear. A three-year research study showed a continuous constant loss of endothelial cells of 1.8 percent a year. Now, nobody could anticipate whether this loss will continue at the exact same price forever, or even its effect on corneal feature.
To decrease long-lasting effects of the device on the corneal endothelium, the FDA is requiring that the new lenses be labelled to specify that they must just be implanted in people whose corneal endothelial cells are thick adequate to hold up against minor cell loss.
A lot more serious complications were couple of: retinal detachment (0.6%), cataract development (0.6%), and also corneal swelling (0.4%). The FDA is needing Ophtec to conduct a five-year follow-up study of its dental implant individuals to much better assess the post-surgical occurrence of cataract advancement, retinal detachment and other ocular conditions.
The Craftsmen lens is meant to be a long-term implant.Though it can be removed operatively, vision might not constantly return to exactly what it was before getting the lens. Since it does not affect astigmatism, individuals with this problem may still call for glasses.


Today’s smartphones are equipped with some impressive photographic technology. Even though DSLR cameras are still more advanced in terms of features and the lenses that can be used, smartphones are more convenient to carry around, plus we almost always have them with us.
So, does it make sense to purchase a camera lens for your smartphone?
A lens can help you to overcome some common smartphone camera limitations. For one, the lens on your smartphone is small, which means only so much light is able to filter through. The digital zoom function, while handy, also usually ends up pixelating your images. Both of these limitations can be overcome with the right lens.
Whether or not you should purchase a smartphone camera lens is dependent on what you usually do with your DSLR camera, how often you take photos, and what you want to use those photos for. A lens will definitely provide you with more possibilities and enhance the overall quality of your pictures. It also gives you the option to edit your photos in a photo editing app instead of using filters.
Most people who have purchased smartphone camera lenses in the past have said it wasn’t worthwhile. However, photographers who want to look at making money with smartphone photography would definitely benefit from purchasing one or more lenses.
The Types of Smartphone Camera Lenses
Here are the types of lenses you can purchase for your smartphone camera:
– Wide Angle. If you love taking street or landscape photos, wide angle lens is a must. It also works well for food photography.
– Telephoto. If you want to be able to capture moments from a distance without losing picture quality, this lens will help you achieve that.
– Macro. If you want to capture more detail and texture in your images, a macro lens is ideal.
– Fisheye. A fisheye lens is ideal for those creative projects.
If you are considering buying a camera lens for your smartphone, be sure to do your research on the different brands that are available and find out what will work best for your phone.

PRAZEN To Present Innovative AR Solution at AWE 2023
News provided byPRAZEN
Mar 22, 2023, 9:21 PM ET
SEOUL, South Korea, March 22, 2023 /PRNewswire/ -- PRAZEN (CEO/Heekyung Kim), a Korean startup specialized in optics for augmented reality (AR) products will present unique new AR glasses and an AR projector at AWE 2023 (May 31 -June 2, Santa Clara, California, USA).
The AR glasses of Prazen has a peculiar optical layout of "Direct Projection", unlike the other previously announced AR glasses. PRAZEN's AR optical module shows much higher light efficiency since it projects lights from micro display into the user's eyes directly while maintaining smaller size of optical module. Up to now, most of the compact-sized AR optical modules have adopted waveguides to minimize the size of AR optical modules, however, the waveguide based optical modules are suffering from the light loss caused by the internal reflection in the waveguides and the reduced diffraction efficiency of related subparts. The light loss of the waveguide based AR glasses causes low light efficiency and dark AR images to the wearers, which let them go through uncomfortable visual experiences, just like wearing dark sunglasses in indoor darker environments. PRAZEN's "Direct-Projection" based AR optical module eliminates the waveguides for their AR glasses, and it shows striking optical performances, highest light efficiency up to 50%, wider field of view up to 70 degrees, minimized module size up to 30cc, thinner combiner thickness up to about 2 mms.
At AWE 2023, PRAZEN will also exhibit another unique projection display based AI assistant device. It can "pop up" 27-inch sized image of an AI assistant human by voice recognition with a compact device. PRAZEN's new AI assistant device features compact size (about 500 cc), high brightness (about 1,000 lumen), lowest throw ratio (about 0.1) and convenient voice and finger touch interaction control. It is clearly different from the existing AI speakers with flat panels (LCDs etc.), in the sense that it can show large images without any cumbersome "black" panel frames. PRAZEN's projection based AI assistant can find its role as a smart home hub, and expand its application into a smart order system, transparent signage and automotive head up displays. The most striking feature of PRAZEN's projection based AI assistant device is that it can be used as an augmented reality display that can be seen without wearing AR glasses, by projecting AR images directly onto the real objects.
PRAZEN is a company founded by optics experts from Samsung Electronics. They established PRAZEN after successfully finishing the "C Lab" project, Samsung's internal spin-off program. PRAZEN secures world-class projection optical technology composed with its own optical algorithm, PRAO®, and various high-tech optical material technology. PRAZEN's highest level optical projection technology enables the smallest optical module to have the widest projection viewing angle reaching up to 160 degrees, which exceeds the competitor's performance by 6 times. Wide viewing angle and compact module size are the key functional factors needed desperately for AR glasses. PRAZEN has applied this optical technology to provide most competitive AR glasses and AR projectors for various applications. All the compelling application features of PRAZEN's AR glasses and AR projectors are firmly based on the compactness of PRAZEN's optical module that can be produced only by the PRAZEN's own optical technology, PRAO®.
PRAZEN has developed many intriguing AR glasses based total solutions for retail, manufacturing industry, education, and healthcare area. It recently supplied AR glasses and its navigation solution to an electric kick board company, and they are in the edge of massive expansion at sight-seeing business.

LASIK & Refractive Care
LASIK stands for Laser In-Situ Keratomileusis. It is one of the surgeries that treat refractive errors of the eye, also known as Laser eye surgery - that can correct a wide range of vision imperfections like myopia , hypermetropia or astigmatism.
LASIK enables freedom of clear vision! Lasik has quickly become the procedure of choice for most patients because they recover quickly and have fewer side effects and complications than with other methods of vision correction. The procedure is characterized by the creation of a flap in the cornea (the surface of the eye),and than a computer-guided excimer laser is used to reshape the cornea to correct the patient’s vision. The creation of the corneal flap improves results compared with traditional Custom Surface PRK (Photorefractive Keratectomy), and also helps to speed recovery and minimize discomfort.
Over the years, Lasik has come a long way. With advance in technology, vision correction has now become an easy and extremely safe procedure. Lasik is the latest technology introduced for patients suffering from Myopia (near sightedness), Hyperopia (far sightedness) or Astigmatism.
After LASIK Surgery ...
☑ you should be able to say goodbye to glasses.
☑ you’ll always know that you have the vision you need all the time, everywhere.

Specialty Contact Lenses
New lens designs and new materials have made contact lenses the choice for vision correction for many people who were not good candidates in the past. Soft toric lenses, which correct astigmatism, are now almost commonplace, as are daily disposable, extended wear and planned replacement lenses. The great majority of contact lens patients use some type of frequent replacement or multi-packaged lenses, making deposits on lens surfaces and other problems associated with standard daily-wear soft lenses a much less common complication.
Eyecare practitioners can now offer their patients lenses, soft or rigid, that are much more oxygen-permeable, allowing the cornea under the lens to breathe almost as well as with no lens in place at all.
There are also recent technology innovations that allow contact lens correction for patients with irregular or scarred corneas, or those with keratoconus to experience better vision than ever before, along with better comfort.
In the late 1950s, contact lenses were a brand new idea; how they fit, moved and their lack of oxygen transmissibility were poorly understood. The only material available to make contact lenses was polymethylmethacrylate (PMMA), a type of plastic that allowed no oxygen at all to pass through it.
One of the first lens designs was called a scleral lens, so named because it was very large, the edges resting on the sclera, the white of the eye. Both the upper and lower lens margins were well under the eyelids and they were large enough to cover the visible eye and then some. Because no oxygen could get through them, they were often fitted in such a way that an air bubble was captured under the lens. Even so, these scleral lenses were extremely uncomfortable and wear time was greatly limited, usually only about two to three hours.
Now, scleral lenses have returned, this time with much better materials and lens designs that allow them to vault over a scarred cornea or one with an irregular shape. They provide
- Sharper vision
- Greater durability
- Easier handling
- Less risk of complications
- More stability on the eye
- Less risk of accidental loss or displacement
- Comfortable all-day wear
There are three size groups of scleral lenses, depending on what is needed for best functionality. All modern scleral lenses are made with advanced, highly breathable gas permeable materials so plenty of oxygen can reach the cornea, regardless of lens size.
- Corneo-scleral lenses and semi-scleral lenses. These are the smallest of the group, but are still much larger than standard rigid gas permeable (RGP) lenses. The edges of these lenses rest near the junction between the cornea and sclera.
- Mini-scleral lenses vault over the entire corneal surface and rest on the front part of the sclera.
- Full scleral lenses are the largest and provide the greatest amount of clearance between the back surface of the lens and the corneal surface.
Scleral lenses are particularly appropriate for patients with corneal scarring, such as from a continuing condition like keratoconus, or from accidental or surgical trauma. They are also used for patients with eyes that were once considered “hard to fit,” meaning that the shape of the eye made conventional RGPs either uncomfortable or too easily dislodged, or both. They are a good option for people who participate in sports, for example.
Another area where scleral lenses are coming into their own is in the patient population suffering from dry eyes. This is because the generous space between the lenses and the eye surface acts as a tear reservoir to keep the front of the eyes more comfortable and moist. Dry eye patients have never been particularly good contact lens candidates, until now; in fact, scleral lenses may become one of the best tools for treating this condition.
Scleral lenses are custom-made to the individual cornea by an eyecare practitioner to provide the best possible eye health, comfort and vision. Because the lenses are larger than conventional lenses, special fitting tools such as imaging devices are needed to measure the eye and in their manufacture. For these reasons, the cost of scleral lenses will be higher than those for conventional lenses, either hydrogel lenses (soft) or RGPs.
In some cases where there is a medical reason for the use of scleral lenses (as would be the case in keratoconus or accidental trauma scarring, for instance) part of the cost may be covered by either medical or vision insurance. Your eyecare practitioner can provide you with the specific costs for your highly individual eyes.
Sometime in the mid-1960s, eyecare practitioners began to notice that young myopic (nearsighted) people who were wearing contact lenses (there were no soft contacts until the early 1970s) were no longer becoming more myopic each year. The lenses had somehow stopped the progression usually seen in this patient population.
Eyecare practitioners began to research this phenomenon and many long-term studies were done to determine if this process could be controlled with the use of specific fitting techniques. Of course, now, with new materials available, orthokeratology (Ortho-K) is one option for reducing or eliminating myopia without surgery.
Ortho-K is a reversible process that gently reshapes the cornea while you sleep; it is suitable for patients with mild to moderate myopia and mild astigmatism. An analogy of how it works is to consider ortho-K to be somewhat like wearing dental braces to straighten and realign the teeth to a specific position. The difference is that the cornea is a highly elastic tissue and it will always revert to its original shape and curvature. For this reason, once the desired reduction in myopia has been achieved, the lenses are worn during sleep so good vision without correction can be enjoyed during the day.
The main purpose of Ortho-K is to be free of both contact lenses and spectacles during the day. It is ideal for individuals involved in sports or for those who work in dry or dusty environments where other types of vision correction may not work well. Ortho-K is especially useful in young people who are becoming more myopic during adolescence, as it will tend to stabilize the refractive error, as long as the patient continues to use the lenses.
Some long-term contact lens patients develop sensitivity to their traditional lenses, even though newer lenses are made with better materials and better designs than in the past. Sometimes known as corneal exhaustion syndrome (CLE), patients who have worn contacts for several years, and notice that their wearing time or lens awareness has increased may have developed CLE. Happily, CLE is not seen as often in recent years, because of better designs and materials. Normal, healthy corneas are steeper in the center and gradually flatten out as they near the sclera; reverse-geometry lenses are made in such a way that they are flatter in the center, and become steeper towards the lens periphery, which causes the cornea to change its shape from the edges instead of in the center. This new fitting philosophy and lens design leaves the central cornea for the most part “as is.”
While most of the vision changes will happen within the first few days, it may take a few months for maximal results and stability. At that time, the eyecare practitioner will determine the amount of retainer-lens wear will be needed to maintain the new corneal shape.
The entire process of Ortho-K is reversible, non-invasive and can be modified easily. It is especially effective for young patients, or for those who are just not comfortable with the risks associated with refractive surgery.
It is important to understand that Ortho-K is helpful for mild to moderate myopia and astigmatism, but not meant for those with large vision corrections for either myopia or astigmatism, or for those who are hyperopic (farsighted).
People who are not good candidates for Ortho-K include those with:
- Eye disease or abnormality that affects the cornea, conjunctiva or eyelids
- Suffer from dry eye*
- Have allergic reactions that may be worsened by contact lenses
- Have high amounts of myopia or astigmatism, or who are hyperopic (farsighted)
- Have a cornea that is abnormally shaped*
*Patients with these particular problems should ask their eyecare practitioners about the new scleral lenses. (see previous section)
The cost of Ortho-K is higher than the cost of standard contact lenses, both because of how the lenses are made and the duration of treatment; the number of lenses needed depends on the individual patient. In general, the overall cost of Ortho-K is usually about half that of laser refractive surgery.
Soft torics, ortho-K lenses, and all the rest of these specialty lenses provide the eyecare practitioner and patient with more choices and will make it possible for some people to wear contact lenses that formerly could not. Others will allow patients who could not previously wear contacts to use them now, with better optics and lens design characteristics. The reality is that we are all different people and we all desire different things from our vision correction modalities; now, with new lens designs and materials, contact lenses may be possible for some people who had very little luck with them earlier.
If you have been told at any time in the past that you could not wear contact lenses, please, ask us about lens options that may allow you to use and enjoy the freedom that contacts provide.

Silicon photonics can be defined as the use of silicon-based materials for the generation, guidance, control, and detection of light to communicate information over distance. When you use a laser to produce light, the output is a continuous wave. So you need an optical modulator to encode data for use in an optical communications link. Current optical modulators run at around 20 MHz, but PhysOrg.com says that in a technological breakthrough in silicon photonics, "Intel Silicon-based Optical Modulator Could Run Faster Than 1GHz." As these modulators can be made out of silicon by using current manufacturing processes, this advance paves the way to a future production of photonics products based on silicon.
Here is the introduction of this article.
Intel researchers have developed a silicon-based optical modulator operating at 1GHz -- an increase of over 50 times the previous research record of about 20MHz. Fabricated in an Intel Fab using Intel's existing high-volume manufacturing processes, the device incorporates a transistor-like structure to encode data onto a wavelength of light.
Intel's breakthrough modulator takes an incoming light beam and splits it into two beams. The beams are then "phase shifted" relative to each other to change the amplitude of the resulting, recombined beam. The result is the ability to change light from bright to dark and thus encode data.
||Here is a diagram showing a Mach-Zehnder interferometer (MZI) modulator with two phase shifter sections (Credit: Intel Corporation).|
What can we expect from these new optical modulators?
By demonstrating how optical modulators can be made out of silicon using Intel's standard manufacturing processes in an existing fab, Intel researchers have removed a significant cost barrier in photonics. The next step is integrating entire photonic devices on a chip with digital intelligence. This should pave the way to produce photonics products based on silicon.
Intel expects to achieve even greater bandwidth in silicon photonic devices by multiplexing many data streams onto multiple wavelengths of light onto one optical fiber. This approach could bring silicon photonics into an age where enormous amounts of data can be exchanged at high speeds on a single fiber.
For far more technical information about this discovery, let's turn to Intel Technology Journal who published a special series of articles about silicon photonics in May 2004. Here is a link to the abstract about Silicon Photonics.
We introduce our approach to opto-electronic integration, silicon photonics, and outline the key functions required for an opto-electronic integration platform: generation, control, and detection of light. Recent research results for silicon-based optical components are discussed including a tunable external cavity laser, a 2.5 GHz optical modulator and a silicon-germanium waveguide-based photodetector. Lastly, optical packaging challenges and potential next-generation designs are presented.
And here is a link to the optical modulator. Here is a short excerpt of the conclusion.
Our modulator with MOS capacitor phase shifters has demonstrated bandwidth performance previously unseen in silicon modulators, and modeling suggests that high-speed modulation at 10 GHz is achievable with design optimization.

Since the popularity of CMOS image sensor, the traditional analog video surveillance is undergoing tremendous transformation. More and more security camera manufacturers launch new high definition analog solutions, which are, HD-SDI, HD-CVI, HD-TVI, and now HD-AHD. All of them can deliver 720P/1080P high definition images, and transmitting the video over traditional coaxial cable. HD-SDI cameras and HD-SDI DVR are the most expensive HD analog equipment among them, which is the main reason HD-SDI technology doesn’t widely used in HD analog surveillance system. Compared with HD-SDI, the cameras based on other three technologies are very competitive.
We have already written some articles to introduce each of these technologies, and the difference between them. Today, we are going to discuss the difference between HD-CVI cameras and HD-AHD cameras.
The main difference: 1.0 megapixel AHD camera adopts OV9712 + NVP2431H solution, while HD-CVI camera adopts the PO3100K + DH9801 solution. In addition to the difference of solution, the price vary greatly, OV9712 + NVP2431 of AHD camera module only costs US$6.5, and PO3100K + DH9801 camera module costs approximate US$10.
Additionally, AHD camera can connect to CRT display directly, the image can display properly. HD-CVI camera connects to traditional CRT, it doesn’t show images. For video live view/recording/playback, HD-CVI cameras need to work with HD-CVI DVR. It seems, the HD-AHD cameras support 960H output mode, which is very convenient for test and installation. Since the AHD cameras can be backward compatible with all traditional analog equipment. Compared with HD-CVI, it has advantages of great compatibility.
Hit a nutshell, AHD and HD-CVI are very similar. Please note that in order to achieve megapixel definition monitoring (720P), the AHD cameras also need to work with AHD DVR.
Introduction to AHD
During old traditional surveillance system’s upgrading and replacing, can’t balance between achieving high definition surveillance and combining old traditional analog system become headache for users. In standard analog surveillance system, 960H is the highest resolution, to achieve much higher resolution becomes impossible mission for traditional surveillance system since its limitation from its technology.
If adopts all high definition (HD) IP camera, the entire system need to replace, this will not only generate high labor cost, but also significantly increased the project budget.
AHD stands for analog high definition, AHD’s birth, is to solve the transmission distance limitations of existing HD-SDI solution. As one of new HD analog solution, AHD supports video transmission over traditional 75-3 coaxial cable up to 500 meters, and it becomes another alternative for HD analog solution. By the way, it inherits and carries forward advantages of traditional analog solution, video signal are uncompressed, keep all the original video details, to truly achieve high definition uncompressed lossless, no video latency effect.
Similar to other HD analog solutions, through using the progressive scan CMOS image sensor, the AHD camera can deliver 1.0 megapixel, 1.3 megapixel, 2 megapixel resolution, added with ICR filter, the camera achieve true day/night video surveillance; and same like the traditional analog system, AHD products support plug-and-play installation, easy to use.
Introduction to AHD Cameras
Recently, some companies offer AHD analog cameras which deliver 1.0 megapixel and 1.3 megapixel resolution. 1.0 megapixel AHD camera adopts OV9712 + NVP2431H, and 1.3 megapixel adopts SONY IMX238 + NVP2430H chipsets.
AHD chipsets are from Korean company – Nextchip, the company launches AHD chipsets (NVP2430H/NVP2431H) which can work with 1.3 megapixel progressive scan CMOS image sensor. The new HD-AHD chipsets are designed to meet the demands of new trend in CCTV market, it is suitable for both analog HD camera and cost-effective HD-SDI applications. The main concept of NVP2430H is supporting 1.3M CMOS sensor and output I/F as analog 1280H(CVBS/COMET), AHD 1.0(720p) and HD-SDI 720p. NVP2431H is supporting 1.3M CMOS sensor and output I/F as analog 1280H(CVBS/COMET) and AHD 1.0 (720p).
Introduction to AHD DVR
Currently, we still haven’t seen the real products of AHD DVR. Since Nextchip is the AHD solution provider, it also offers AHD codec chipset – NVP6114. NVP6114 is designed to encode and record the video footage from AHD cameras. AHD DVR based on NVP6114 can support 4 channel AHD and 9 channel audio codec. It can work with 1.0 megapixel and 1.3 megapixel AHD cameras, deliver high quality images.
NVP6114 includes 4-Channel AHD1.0 RX and 9-Channel Audio Codec. 4-Channel AHD1.0 RX delivers high quality images. It accepts separate 4 CVBS/COMET/AHD1.0 inputs from Camera and the other video signal sources.

Coatswroth Eye Clinic offers following specialists lenses:
A varifocal lens designed for people who regularly require a progressive lens in an active and dynamic environment. The varifocal is applied to the lens in such a way that it gives the wearer a much wider field for distance and intermediate, moving the reading area a little further down the lens. This means when playing golf, for example, when bending over to take a swing your reading area will not interfere but is still substantial enough to record your all-important scores!
iOffice and iDesk
These are both progressive lenses designed for office type environments. Where a traditional varifocal has distance, intermediate and reading, these lenses concentrate on giving the wearer the best possible vision for intermediate and near work. They have also been developed to allow the wearer the most natural head position therefore reducing neck strain associated with long term computer use.
The iOffice allows the wearer to see a little further into the distance, so great for those who work in a general office or a shop, for example.
The iDesk has the widest area for computer and close work, so great for those who spend long periods of time at a VDU screen.
A varifocal lens designed with the specific vision requirements of driving in mind. Clear distance vision is the absolute priority, giving the wearer the widest field of view in the distance possible. It also gives improved middle distance vision compared to other progressive designs for reading the dashboard and seeing in mirrors.


Choosing the right technologies, with the best and most appropriate set of functions, is pivotal in Geomatics. Here at Merrett Survey Limited, we are constantly looking for ways to enhance the efficiency of our laser scanning methods with the view of producing the most efficient and accurate results as possible. Due to their capability to take 3D measurements, laser scanning systems are utilised to survey all types of environments, whether it’s buildings, road networks or railways for example.
Laser scanning can be summarised in a few simple sentences. It is a technology that allows us to capture environments in 3D with speed and accuracy. Each surface that the laser comes into contact with is reflected back and recorded as a surface point, before being assigned a colour and surface reflectivity. Hundreds of millions of data points can be captured in a single session which, when combined, are called a point cloud.
Benefits of laser scanning:
In it simplest form, LiDAR stands for light detection and ranging, just as radar stands for radio detection and ranging. Initially, LiDAR scanners were attached to aeroplanes in the 1960s and t wasn’t until the 1980s that the technology became appropriate to use in the geospatial industry. These were utilised as commercially viable GPS systems, which provided industry professionals with the ability to create concise, geospatial measurements.
In the surveying industry, we often use the phrase LiDAR for aerial surveys and laser scanning for ground based work, but the principle is the same – using a laser beam to measure the distance to an object.
With many different technologies on the market, there are a vast range to choose from when thinking about your client needs and specifications. However, the Leica RTC360 is an advanced and highly sophisticated product which ticks all of our boxes.
The 3D laser scanner, complete with HDR spherical imaging system and Visual Inertial System (VIS) allows for real time registration. With its ability to scan large scale areas with immense speed, precision and agility, the RTC360 is the ideal tool to further our laser scanning and LiDAR expertise.
Some key benefits of the Leica RTC360 include:
Speaking of the benefits of the RTC360, owner of Merrett Survey Limited, Peter Merrett said: “We have a reputation for applying the latest technology, yet we only apply it when it has been proven to bring genuine benefits – either in terms of speed or accuracy and quality of the end product. This instrument certainly speeds up our fieldwork. Plus, on the quality front, the built in HDR camera is of very high quality.
“The photographic part of the scan process tends to slow down the scanning work considerably, although, with this laser scanner, the imaging time is only 2 minutes per set-up. This enables us to colourise the point clouds we produce to a very high standard and also gives the client a greater insight into the structure or asset we are surveying”.
Whether its laser scanning large storage tanks or vast areas of land, laser scanning technology such as the RTC360 allows us to deliver fast, pinpoint results. Contact us to find out more about our laser scanning and LiDAR services in greater detail and to discuss the full uses of the Leica RTC360.


With the new "Black & Light" adhesives, Panacol has developed a new adhesive technology: deep curing black epoxies. Black epoxy adhesives from Panacol's Vitralit product range can now be cured with UV light sources in thicker layers, without resorting to secondary curing mechanisms.
Conventional black UV adhesives have a major disadvantage: the black color absorbs a high proportion of the UV intensity, which means that the energy needed to fully polymerize an adhesive can only penetrate a few micrometers. This results in surface “skin” formation on black adhesives, but not a complete cure. They must then be cured in a secondary thermal curing process at temperatures above 100°C.
Panacol's new "Black&Light" technology enables the complete curing of black epoxy adhesives with LED UV energy. Depth of cure can range from a few hundred micrometers to several millimeters. The adhesives are suitable for encapsulation, glob top, or edge bonding in electronics manufacturing, as well as for optical adhesive systems where high OD values (optical density) are required. They are suitable for optoelectronic applications to help minimize reflections and enhance sensor transmission values.
A typical manufacturing process using "Black&Light" technology can be as follows: The black adhesive is dispensed and cured with the appropriate wavelength and intensity. During the curing process, the “Black&Light” technology within the adhesive enables the UV rays to penetrate and complete a full cure. Once the adhesive polymerization is complete, the structure of the "Black&Light" technology prohibits light transmission, resulting in a fully cured adhesive system that remains irreversibly black.
The "Black&Light" technology is compatible with many Vitralit® epoxy adhesives from Panacol. Custom adhesive solutions can be created to accommodate unique requirements for amount of light blocking and depth of cure. The "Black&Light" adhesive systems can be very specifically adapted to specifications of the respective application.
Another major advantage of the "Black&Light" adhesives is storage. Many single-component, black epoxies require deep frozen transportation and storage. The "Black&Light" epoxy adhesives can be stored and shipped at room temperature or under normal refrigeration.For further information please contact us.

Understanding anatomy of the eye – the function of crystalline lens and vision
The eyes are not only the windows of the soul, but our eyes are the windows of the world in the way that we allow us to observe our environment and to perceive the beauty of the landscape around us. If we are to the point where we can better understand the functioning of the various parts of our visual system, it is worth exploring while we understand that our eyes allow us to get a clear and crystal clear picture. One important part of our eye is called a crystalline lens. The crystalline lens of the eye is located behind the eye of the eye and is part of the visual system that is in the corrosion that is called the middle layer of the eye. Therefore, some information about how the crystalline lens helps to improve the visual system's performance:
The eye's crystalline lens plays an integral role in helping the visual system work more effectively due to the fact that the granular muscles of the eye work together to remote and close objects can be brought to a pure focus. It is therefore important that the rest of the eye work effectively together. For example, the effect of eyepiece muscles will change the shape of the lens to ease our eyes. can focus on different objects at different distances.
For example, when looking at a distant object, the effect of ciliary muscles on the spectacles creates its shape from the perspective of a thicker circular shape. This special shape is ideal for clear vision because it allows for easy bending at the exact angle so that the bright images go directly to the retina to give you a clear view of the distance. Likewise, when looking at a nearby object, granular muscles work in conjunction with the eyepiece, which creates a shape for a lens lens, as it helps close-ups as in reading, studying digital devices and computers.
The eyes are the most interesting organs in the human body. Various parts work together to allow us to see clearly and clearly visible objects near and far. A crystalline lens is a strange part of the eye, which is especially important as the eyepiece shape changes the eyepiece's muscle so it fits better with nearby objects and makes it look more flexible to help us see distant objects.
A crystalline lens is an important part of the eye that helps to show both distant and near objects. This part of the eye is essential because it helps in the various parts of the eye to work effectively with the action taken with the granular muscles of the eyes to bring close and close objects to a pure focus. The crystalline lens is an important part of the eye, as without this part of the eye, the eye contours, such as shortness of vision and vision, will become more common. It's just one of the interesting things about the eyes that it is worth exploring to bring us to do things that we need to do to take care of our precious vision that it serves us for a lifetime.

There are multiple coatings applied to the F-35, and achieving the correct thickness is not always possible with the robotic spray process simply due to the complex contour, which can be rather severe in places, and the paint plume being sprayed. To achieve a target thickness, an operator must measure the thickness at several discreet points, then sand or add material as needed. The manual measurement process requires a stencil to be placed on the aircraft to identify the measurement points, and can be prone to spot sanding, leading to an out-of-tolerance coating. A robotic inspection system was developed to address this problem by robotically scanning the surface of the aircraft with a metrology device, then projecting a visual aid which guides the operator to where sanding or adding material is needed. The system is comprised of a sensor and projector which are attached to a collaborative robotic arm, all of which is mounted on an Autonomous Mobile Robot (AMR). The AMR drives the system into place in front of the desired inspection area. From there, the system scans the surface of the aircraft to measure thicknesses. The results of the inspection are then optically projected onto the surface so the operator can work the coating and rescan zones as needed.


If you’ve always fancied yourself as a bit of a David Bailey or Phil Stern but your shots always end up looking out-of-focus and blurry, then new camera technology could hold the answer.
While our smartphones are a convenient tool for taking quick snaps, as we always have them with us, the results aren’t always perfect.
But, 2013 could be the year when blurry smartphone photographs are consigned to history because of new technology which allows you to alter the focus – after you have taken the shot.
Japanese electronics innovator Toshiba is busy working on a camera module for both smartphones and tablets. While auto focus usually does the trick, there are times it concentrates on the wrong subject. But Toshiba’s new gizmo will mean you can correct that.
It works through the use of half a million tiny lenses which each capture a slightly different image, with a different focal length.
The camera will be able to measure the distance between objects, in a similar way to the method used to capture 3D images, and the photographer will then be able to move the focus between details in the foreground and background, to create the “perfect” image.
Compared to the way an insect’s eye works, Toshiba is busy pitching its new invention to mobile manufacturers. The manufacturer says the camera sensor will also work with videos, which will certainly broaden its appeal.
It should certainly be feasible to include the new technology in smartphones as it currently measures just one cubic centimetre.
The new innovation comes after the Lytro Light Field Camera which caused a bit of a storm when it was released in 2012.
The Lytro camera also lets you create pictures that you can refocus after you’ve taken them. You can even share them online, letting your friends refocus them too if they spot a subject of interest in the frame.
As the developers behind the Lytro say: “The Lytro camera lets you capture and share what you see in a whole new way.
It’s the first consumer camera that records the entire light field – all the rays of light traveling in every direction through a scene – instead of a flat 2D image. And that changes everything.”
Others, including micro-optics firm Heptagon and Pelican Imaging have also announced similar smartphone sensors.
But while Lytro may have had a head start, it seems other technology firms are now hot on its heels. And, while Lytro was hoping it would, long-term, be able to take advantage of the smartphone market, it just may be that Toshiba wins the race.
While, the Toshiba sensor is still very much a work in progress, the Japanese multinational, has plans to commercialise its new module before the end of the year. The innovation could change the way we think about taking photos on our smartphones and tablets. We’ll just have to wait and see which mobile manufacturers take on the new technology.

Finished EIP projects
Non-contact fever detection for safe and efficient animal care
The ambition of the project was to develop a non-contact fever detector for livestock, that measures the surface temperature of the cornea using thermal cameras. The purpose of the innovation is to facilitate animal care, minimize production losses and increase the efficiency of both dairy and pig producers' businesses. The aim was also a fixed system solution for continuous fever measurement where the animals pass the same camera station (eg dairy cows) and a handheld system solution for meat animals, pigs and horses where the heat camera communicates interactively and in real time with a server (eg cloud solution to store directly data on the animal).


When used directly on the press brake, the KeMes angle measurement device automatically determines any bent angle. Time no longer needs to be spent on manual spot checks.
KeMes enables complete quality control directly in the running production process. It is possible to immediately respond to any angle deviations.
The patented angle measurement solution functions for different machine types and manufacturers and can be retrofitted to existing press brakes at any time without intervening in the machine control.
Whether directly on the press brake, for manual spot checks or incoming goods inspection – the digital protractor KeMes is very versatile.
KeMes supports the recording of the measurement values, which can then be used to analyze the production process.
Equipped with a Bluetooth interface, the KeMes variants A200 and A205 allow the automatic transfer and processing of angle values. However, this requires an integration of the device by the machine manufacturer.

Lumix is Panasonic's brand of digital cameras, ranging from pocket point-and-shoot models to digital SLRs. Many Lumix models are fitted with Leica lenses that have been designed by Leica's German optical engineers and are assembled in Japan, some are rebadged as Leica cameras with different cosmetic styling. Leica had a similar relationship with Minolta in the past, where late model Leica SLRs (and some 35mm point and shoot models) were strongly based on Minolta bodies.
Most Lumix cameras use different releases of the Panasonic Venus Engine for digital image processing; the original version was followed by II, III, IV, HD (2008), V (2009), and VI, HD II, FHD (2010).
Panasonic produces all of Leica's branded digital point and shoot cameras in Japan, but not film cameras, the Leica M8 or Leica M9 digital rangefinder cameras, or the Digital Modul R digital camera back for the Leica R9 film SLR.
Some cameras come in several colours, indicated by a suffix letter: K is black, S silver, A blue, R red, W white. Most lower-price cameras have small sensors of about 10.2 mm / 1/2.5". More expensive ones often have sensors of about twice the area, 14.1 mm to 15.4 mm / 1/1.65" to 1/1.8". dSLRs and Micro Four Thirds cameras have much larger sensors. Larger sensors produce a better signal-to-image-noise ratio and better dynamic range. The GH series of Micro Four Thirds cameras have a unique 'multi-aspect' sensor, that is larger than the lens image circle. This allows use of three different aspect ratios, 4:3, 3:2 and 16:9, to be used natively. As a result, the image diagonal remains the same in all three aspect ratios and provides full coverage of the sensor and a larger field of view with higher resolution than one would get by simply cropping the 4:3 aspect to the narrower ratios.
- DMC-FS: Ultra-compact mid-range, relatively typical cameras. The FS range was launched in January 2008. This series includes the FS3, FS4, FS5, FS20, FS6, FS7, FS15, and, FS42.
- DMC-FX: Ultra-compact high-end, relatively typical cameras. The FX01 was the first ever ultra-compact (considering Ricoh R series as compact) with a true wide-angle 28–102 mm lens, sharing now (20 Jan 2007) this feature with its siblings FX07 and FX50, as well as with the Canon SD800 IS (IXUS 850 IS in Europe). Unlike most of the other Lumix lines, the FX series tends to have a more stylish look (as opposed to the generic silver or black), targeted at social photography. Includes the FX1, FX5, FX2, FX3, FX7, FX8, FX9, FX01, FX10, FX12, FX30, FX37(38), FX50, FX07, FX100, FX33, FX55, FX35, FX150 (1/1.72"), FX500, FX48 (FX40 in Europe), and FX580 (FX550 in Europe). The Panasonic Lumix DMC-FX30 was announced as the world's slimmest camera with a 28 mm equivalent wide-angle lens. The Panasonic Lumix FX35 equips with 25 mm Ultra-Wide-Angle Lens. The FX500 is the first Panasonic to feature a touch-screen interface.
- DMC-FZx (excluding DMC-FZx0 models): Compact ultra-zoom higher-end cameras. These cameras are described as compact but are relatively large, have extensive controls (although models earlier than the FZ7 do not have manual focus), and long zoom ranges, typically 12× with extending zoom lens. Includes FZ1, FZ2, FZ3, FZ4, FZ5, FZ7, FZ8, FZ18 (18× zoom, 1/2.5"), FZ28 (18x zoom, Venus IV) and FZ35/FZ38(Europe) (18x zoom, Venus HD).
- DMC-FZx0: Bridge digital cameras, resemble digital SLRs in many ways, but have a non-interchangeable, non-extending zoom lens. The later models from the FZ30 are large and heavy, have a wide zoom range (12×) and extensive manual controls, including fully manual focus and zoom rings on the lens. The range comprises the FZ10, FZ20, FZ30, and FZ50 (14.1 mm / 1/1.8").
- DMC-G: Panasonic's Micro Four Thirds System line, advertised as a "reinvented D-SLR" without mirror. The first camera in the line is the G1, released in late 2008, which has an electronic viewfinder (EVF) and interchangeable lens (EVIL class). It does not use the mirror and pentaprism of a true SLR, so is smaller and lighter. It has many of the features of a DSLR and of a compact digital camera, but no movie mode. The GH2 was released in October 2010 as a successor to the GH1 and improves upon the video recording capabilities of its predecessor and incorporates many upgrades such as a higher resolution sensor and the fastest contrast detect autofocus system implemented to date. In September 2009, Panasonic released the GF1, a 12 megapixel compact Micro Four Thirds camera featuring 720p HD video. This model was followed by the GF2, a smaller version of the GF1, incorporating 1080p HD video.
- DMC-L: Panasonic's DSLR line. It uses the Four Thirds System lens mount and along with the Olympus E-330 was one of the first DSLRs capable of displaying live image view on the LCD screen. Models include the L1 and L10.
- DMC-LS: Panasonic's cheapest line, budget plastic compact cameras powered by two AA batteries. Includes the LS1, LS2, LS3, LS60, LS70, LS75, LS80, and LS85.
- DMC-LX: A compact high-end camera line, with full manual exposure and focus controls (with joystick control rather than focus ring), and RAW recording, unusual in compact cameras. Includes the 8 megapixels LX1, the 10 megapixels (1/1.65") LX2, and the 10 megapixels (1/1.63") LX3 with a 2.5x f/2–2.8 24–60 mm (35 mm equivalent) lens. (Announced Jul 2008, shipping since late Aug 2008.) The successor to the LX3, the LX5 was announced in July 2010 and features an unchanged 10.1MP (1/1.63") sensor, but with an improved telephoto 3.8x f/2–3.3 24–90 mm (35 mm equivalent) lens.
- DMC-LZ: Budget, but more advanced and with more user control than many other digital compact cameras. The most notable feature is a 5× (37–222 mm) optical zoom range. Includes the LZ1, LZ2, LZ3, LZ5, LZ6, LZ7, LZ8, LZ10 (Jul 2008).
- DMC-TS: waterproof, shockproof, and dustproof point and shoot camera. Includes TS1 (FT1), which also has limited high definition video capability.
- DMC-TZ: Compact, point and shoot 10× zoom cameras with image stabilization. Includes the TZ1, TZ2, TZ3, TZ4, TZ5 (Known as the TZ15 in Asia), and TZ50 (TZ5 with Wi-Fi). The TZ1 uses folded optics, with a prism. TZ1's successors use a traditional design without folded optics, hence the barrel extends further out during operation. The TZ series stands out against other compact digital cameras by achieving a 10x optical zoom with a 28 mm* wide angle lens in a small compact body. *equivalent to 35 mm camera. In 2010 Panasonic released the latest model, the TZ10 (ZS7 in the United States), which has a 12x (25 - 300 mm) optical zoom and incorporates GPS. It also features 720p HD video capability. On January 25th 2011, Lumix DMC-TZ20 (ZS10 in the United States) was announced. Features includes 16x zoom (24-384mm), 14.1 Megapixel MOS, 1080/60i AVCHD video, high speed shooting at 10 fps at full resolution, 60 fps at 3.5 Mpix resolution and high speed video at 220 fps at QVGA resolution.
- DMC-ZS: Compact ultra-zoom high-end (offering HD video) cameras. Announced in January 2009 as a successor to the successful TZ series. It is distinguished by having high-grade still shooting and offering HD video functions. Includes ZS1 (TZ6) and ZS3 (TZ7). The ZS3 is advertised as "the world's first digital camera that records motion image in AVCHD Lite", records 720p HD video with stereo audio and has a dedicated video record button (which replaces ZR1's 'extended zoom' button). ZR3 replaces ZR1 in some countries.
