Corneal disease is a major cause of blindness world wide and transplantation with a human donor cornea remains the main clinical line of therapy. However, the demand for corneal donation outpaces the supply, leading to delayed visual rehabilitation for several hundreds of patients worldwide who are awaiting corneal transplantation. Furthermore, conventional corneal transplants has a high risk of failure in patients with severe ocular surface disease and vascularised cornea often necessitating repeated transplant procedures without much visual success. A recent UK graft registry assessment showed up to 50% of patients requiring a full thickness corneal transplant (PK) had such high risk characteristics with poor prognosis with conventional corneal transplantation. A synthetic cornea could offer the necessary solution for these patients and remains an unmet need in this field. In response to our project grant application in March 2020, the Medical Research Council (MRC) awarded a £1.37m for this project as a career development grant to Dr Hirak K Patra, University of Cambridge and University college London in collaboration with Prof Madhavan Rajan at Addenbrooke’s Hospital and Anglia Ruskin University, Cambridge to develop a Assisted Regeneration Artificial Cornea (ARCs) which will mimic biological properties of the human cornea and have additional function as a mediated device with theranostic potential. Overseas collaboration with University of Montreal, Canada and Harvard, United States, would bring international expertise to our project. This combined diagnosis and therapeutic approach will enable disease monitoring and treatment to severe corneal scarring disorders for the first time and promises to address the unmet need in the field for artificial cornea.
Laser technology enables surgeons to operate with greater precision when compared to conventional surgery. Addenbrooke’s Hospital is the first NHS unit in the UK to install the state-of-the-art ‘Femtosecond’ laser system. This infrared laser, with its ultra-precision, brings the potential to revolutionise eye surgery in the East of England, improving care and ensuring more patients can benefit.
The femtosecond laser project was led by Mr Madhavan Rajan, Consultant Ophthalmologist in 2016 and he performed the first femto procedure in Cambridgeshire, and since have completed several hundred procedures. Femtolasers help improve safety and accuracy when treating visually compromised patients with cataract and corneal disorders, thanks to Addenbrooke’s Charitable Trust and the Cambridge Eye Trust for their generosity to bring this innovative technology to patients in Cambridge and the East of England region'.
Cambridge Vision Clinic based in Cambridge, UK features an excellent team of eye care professionals offering a personalised, safe approach to patients with cataract and eye disorders for over 10 years.

(LOS ANGELES) – A collaborative team from the Terasaki Institute for Biomedical Innovation (TIBI) has developed a contact lens prototype that is specifically designed to prevent contact lens-induced dry eye (CLIDE). The lens alleviates this condition by facilitating tear flow in response to normal eye blinking. This approach can relieve the discomfort, visual impairment, and risk of inflammation experienced by millions of contact lens users suffering from CLIDE.
Of the 140 million contact wearers worldwide, 30%-50% suffer from CLIDE. The problem arises from the insufficient flow of tears from the contact lens's outer surface to the surface behind the lens. This leads to excessive tear evaporation and all the problems associated with CLIDE.
Current treatments for this condition include rewetting drops, gels, or lubricants, more frequent lens replacement, or changes in the lens material. There are also eyelid treatments, such as eyelid massage and warm compresses. In more severe cases, physical stimulation of the tear glands may be utilized, as well as the use of punctum plugs, devices inserted into tear ducts to block drainage. Efficacy varies among these treatments, however, as well as potentially harmful accumulations of drugs in the body and the non-user-friendly methods that contribute to patient noncompliance.
There have also been previous attempts to use contact lenses in treating dry eye syndrome, such as graphene-coated lenses designed to minimize moisture loss and self-moisturizing lenses stimulated with metallic electrodes. But these methods are costly and impractical and may compromise patient safety and comfort.
The TIBI team’s approach uses a contact lens design that incorporates microchannels to facilitate tear flow movement and flow so that dry eye can be avoided. This flow can be achieved by pressure applied by normal eye blinking so that no external devices are needed.
In fabricating their contact lens prototype, the team utilized a time-saving method – their lens mold was made from a silicone polymer mixture; this allowed for easy removal of the lens cast on it by gently bending the mold. Previous methods necessitated a twelve-hour soak in hot water to remove the lens. The approach resulted in high-quality, smooth microchannels, as well as lenses that could be thirty times thinner than previous lenses. A custom device was used to fabricate reservoirs at the ends of each microchannel for the inflow and outflow of liquids.
Innovative techniques were also utilized when encapsulating the microchannels in a sandwich-like assembly under a capping lens layer. Initially, the preparation of the two lens surfaces for stronger bonding dehydrated the lenses, causing them to curl. This problem was solved by affixing the two lenses to holders using water-soluble glue. This served not only to enable a more uniform bonding of the lenses but protected them from damage as well.
After rigorously testing their encapsulated microchannel lenses for stability and leakage, the lenses were subjected to a series of experiments using a device that the team designed to simulate a blinking eyelid. This device was integrated with the lens prototype to create artificial eyelid pressure on the lens to stimulate tear flow.
After various experiments, a configuration that proved effective was microchannels with square cross-sections arrayed in a novel circular pattern on the lens surface; this was compatible with the function and curvature of the lens and allowed for optimum liquid flow.
The team demonstrated a proof-of-concept validation of their lens’ ability to guide tear flow originating from the lens surface to the underside of the lens to combat dry eye syndrome. The team quantified these flows and established that the flows were driven by low-pressure levels like those from normal eye blinking. Further tests could be devised to test these lenses on animal models and in patients.
“The inventive methods that our team has employed bring a potential solution for millions of people,” said Ali Khademhosseini, TIBI’s Director and CEO. “It is the hope that we may extend our efforts to bring this solution to fruition.”

Experimental Fiber Optic Cables To Warn of Potential Pipeline Damage
First Field Test of High-Tech Method for Improving Safety of the Nation's Gas Delivery System
Des Plaines, IL - Every year natural gas pipelines are damaged by construction activities even though warning signs often mark utility right-of-ways. Now, a new fiber optic cable system being tested in a joint U.S. Department of Energy/Gas Technology Institute (Des Plaines, IL) project could give gas pipeline companies a remote method for detecting encroaching construction activity and help prevent potentially harmful accidents.
||A technician deploys the underground fiber optic "early warning system."
This month, in the first field test of the system, crews from ANR Pipeline Company, a subsidiary of El Paso Corp. of Houston, TX, buried fiber optic cables over one mile of active pipeline in northwest Indiana.
During the next several months, construction equipment will create vibrations in the ground, causing compressions in the soil surrounding the pipeline. If the vibrations and soil compressions are sufficiently close to the pipeline, the fiber optic cable will bend ever so slightly. Even a minute deformation in the cable will change its light transmission and reflection properties and send an early warning of a potentially hazardous encroachment.
"Third-party damage" is the major cause of damage to natural gas transmission pipelines. As urban areas expand and the demand for natural gas increases, buildings are being constructed increasingly closer to pipelines. More construction near pipelines increases the probability and consequence of damage.
Several approaches have been suggested or are being studied for detecting potentially harmful impacts on the hundreds of thousands of miles of underground gas pipelines that crisscross the United States. Satellite, ground-based visual, and global positioning system monitoring systems are among the new technologies being studied to help protect the integrity of the nation's pipeline system. Fiber optic technology, however, is projected to be one of the least costly options. Moreover, it can help prevent pipeline damage, not simply detect it after it happens.
GTI will test four different fiber optic cables. Three multi-mode fibers (Hergalite®, Corning® 62.5/125 and Corning® 50/125) and one single-mode fiber (Fibercore Limited's SM600), were buried above the pipeline approximately 15-50 centimeters below the surface of the ground.
Construction equipment does not have to break the fiber to be detected. When intrusion is detected, an alarm sounds, alerting the pipeline company of equipment encroaching on its pipe. This would enable pipeline companies in the future to take immediate action to stop unauthorized excavation and prevent potential damage to the pipeline.
The system not only can warn of approaching construction activity, it can also help operators pinpoint where along the pipeline the potential hazard is developing. Stresses in the fiber optic cable will cause some of the light to be reflected back to its source. Because the velocity of light in the fiber will be known, the location of the encroaching equipment can be determined by measuring the time for the reflected light pulse to return.
The largest technical barrier to perfecting fiber optic cable technology for pipelines is in developing methods to distinguish between potentially hazardous and benign intrusions into the right-of-way. Compared to benign activities and noises, such as pedestrian traffic and thunder, construction equipment will be large and have characteristic signals. One goal of the project is to minimize or eliminate false readings from the cables through all seasons and soil conditions.
The research project is funded through the DOE Office of Fossil Energy's Natural Gas Delivery Reliability Program, which is managed by the National Energy Technology Laboratory. Results of the project are expected in the fall of 2003.

Born on October 30, 1943 in Saint John, N.B., Canada, Professor Paul Bruce Corkum received his Bachelor’s degree in physics from Acadia University in Wolfville, NS, Canada in 1965, and both his M.S. and Ph.D. in Physics from Leghigh University in Bethlehem, PA, USA in 1967 and 1972, respectively. He joined the National Research Council of Canada since 1973 and currently holds the Joint University of Ottawa-NRC Chair in Attosecond Physics.
Professor Corkum is a renowned authority on lasers and their applications. For more than three decades, he has been developing and advancing knowledge on how intense laser light pulses can be used to study the structure of matter. His research has consistently been “characterized by a deep physical insight accompanied by elegant models and supported by highly original experiments” which led to major advances in atomic and molecular physics. He won the KFIP in Physics jointly with Professor Ferenc Krausz in recognition of their independent pioneering work which enabled them to capture the stunningly fast motion of electrons in atoms and molecules with a time resolution down to attoseconds (an attosecond is one billionth billionth of a second).
Professor Corkum’s innovative research and contributions to physics have earned him wide recognition. He is a Fellow of the Royal Society of Canada, Fellow of the Royal Society of London and Foreign member of US Academy of Sciences. He is also a Fellow of the Institute of Physics, the American Physical Society and the Optical Society of America. In 2007, he was inducted to the Order-of-Canada. His other honours and awards include: Gold Medal of the Canadian Association of Physicist for lifetime achievement in Physics (1996); Einstein Award of the Society for Optical and Quantum Electronics (1999); Tory Medal of the Royal Society of Canada (2003); LEOS distinguished lectureship; (2001-2003); Her Majesty Queen Elizabeth II: Golden Jubilee Medal (2003); Charles Townes award of the Optical Society of America (2005); IEEE’s Quantum Electronics award (2005); Killam Prize for Physical Sciences (2006); The American Physical Society’s Arthur L. Schawlow Prize in Laser Science (2006); the Natural Sciences and Engineering Research Council of Canada (NSERC)’s Polanyi prize (2007); NSERC’s Herzberg Prize (2009) and Zewail Award of the American Chemical Society (2010). He was also awarded honorary doctoral degrees from both Acadia University (2006) and the University of Western Ontario (2009) in Canada.
Professor Corkum authored more than 240 peer-reviewed papers, most of which in leading physics journals; he also edited several books and gave approximately 23 public, plenary or invited lectures per year. He mentored numerous MSc and PhD, Postdoctoral Fellows and visiting scientists in his laboratory. He also served for six years as a member of the editorial board of the Journal of Physics B, became its Deputy Editor from 2009-2011 and currently its Editor. He is also a member of the editorial advisory board of the International Journal of Nonlinear Optics.
Professor Paul B. Corkum and Professor Ferenc Krausz were recognized for their independent pioneering work which has made it possible to capture the incredibly fast motion of electrons in atoms and molecules in a “movie” with a time resolution down to attoseconds. An attosecond is a vanishingly short time. One attosecond compared to one second is like one second compared to the age of the Universe.
When intense ultra-short laser pulses are focused into a gas, a laser-like beam of attosecond pulses of ultraviolet light is produced.
Professor Corkum was the first to explain this phenomenon with a conceptually simple model. He has harnessed this process for pioneering studies in collision physics, plasma physics, and molecular science. He has even been able to produce tomographic images of the movement of electrons in molecules.


Three-dimensional structures for photonic crystal applications have been fabricated up to now either by pure bottom-up approaches like colloidal self-assembly, by pure top-down approaches using VLSI technology or by interference lithography. Here we demonstrate the fabrication of three-dimensional silicon networks by a self-stabilized electrochemical etching technique on lithographically prestructured single crystalline substrates. Using a square two-dimensional lattice and a modulated current-voltage-profile, a columnar porous structure with strong diameter modulations is obtained. Subsequent homogenous and isotropic (i) or even anisotropic (ii) etching converts the columnar structure to a cubic geometry of high porosity and an air filling fraction of 80%. In the case of an isotropic etching the porous material is build up of intersecting air spheres in silicon. The optical characterizations along various high symmetry directions of the crystal confirm the achieved periodicity and shape and suggest this material for photonic crystal applications. According to theory this arrangement of air spheres in silicon opens a complete three-dimensional photonic bandgap of about 4.9% centered at 3 µm. Moreover, the subsequent anisotropic etching of the initial porous structure, which exploits the crystallographic nature of the substrate used, converts the former circular cross-section of the pores into an almost squared one. We theoretically study the dispersion behavior of PCs being fabricated by this developed technique. In addition, we present experimentally realized structures and characterize the photonic crystal optically. The reflectance measurements are in good agreement with corresponding bandstructure calculations. A major part of this work deals with the investigation and characterization of fabrication-related disorder and its prevention. This process allows the introduction of defect layers laterally during the etching process as well as vertically - by lithography - achieving a three-dimensional nanopositioning control. Moreover, the introduced process extends the variety of designing and sculpturing three-dimensional microstructures to meet the requirements of a multitude of micro- and nano-technological applications.

The physical centres of the various imaging arrays on the LT are not necessarily aligned with the optical axis of the telescope. The LT's normal acquisition procedure is therefore to first place the telescope's nominal pointing centre on the target (i.e., "blind pointing") and then issue a "Focal Plane" command which offsets the centre of the instrument field-of-view onto the requested coordinates. This process may be subject to an absolute pointing error of around 10 arcseconds. While this is usually adequate for imaging, more precise acquisition is required for spectroscopy.
Target acquisition for spectroscopy may be achieved in two ways. Initially, an image of the target field is always obtained using the LT's work-horse wide-field optical imager (currently IO:O). That image is then used either to identify the brightest source in the field and to centre on that target, or to calibrate the pointing of the telescope by identifying stars in the field and fitting a world-coordinate system (WCS) to the image. Based on this WCS-fitting process, the telescope is offset to move the target position onto the spectrometer (for FRODOspec this is to within 2 arcsec of the centre of the fibre bundle). Two or three images may be used to fine-tune the telescope position before switching to spectroscopy mode and beginning the observation.
For more details see the FRODOspec instrument page. Note that this FINE TUNE acquisition process can in principle be used for any instrument, not just with the LT's spectrometers. However, this process increases the overheads on the project (by a few minutes) and should therefore only be used if telescope pointing at the ±2arcsec level is important.
Due to flexibility problems with the coolant pipes, we were forced to dispense with the practice of routing them through the cable wrap in the cassegrain axis rotator. For most observations the rotator is therefore set to one of the "cardinal" sky angles of 0, 90, 180 or 270 degrees. This means that images will be automatically rotated to one of these angles, the choice being the one that will give the longest possible uninterrupted observing time before reaching a mechanical rotator limit. It is possible that the sky angle will change during a (very) long series of exposures - but not during an exposure!
Specific control of field rotation is available for cases where the science requirements of the programme demand it, but in general we recommend leaving the rotator on its default automated setting.
Though observations at different epochs may be obtained at different sky orientations, the default choice of "cardinal" sky angles means that the overlap between repeated images of the same field is always maximized, which is important for programmes relying on secondary standards within the fields. The standard "North at the top" image display orientation is simple to achieve in an image viewer, using only 90 degree rotations.
Pointing below altitude 40 degrees
Occasionally the telescope does not point well below Alt ~ 40 degrees. This is due to a problem with the mirror support on one of the three sectors behind the mirror cell. Images can be obtained that are shifted by 30-40 arcsec. However, this problem does not affect telescope tracking or guiding, so the image quality itself should not be affected. If your science requires that a target be positioned on the same spot on the CCD each time it is observed, acquisition similar to what is used for spectroscopy can be used (as noted above). Please contact us for further details.

GAITHERSBURG, Md. – Researchers at the National Institute of Standards and Technology (NIST) have published landmark test results that suggest a promising class of sensors can be used in high-radiation environments and to advance important medical, industrial and research applications. News-Medical.Net reports. Continue reading original article
The Military & Aerospace Electronics take:
3 Dec. 2018 — Photonic sensors convey information with light instead of electric currents in wires. They can measure, transmit, and manipulate streams of photons — typically through optical fibers — and are used to gauge pressure, temperature, distance, magnetic fields, and environmental conditions.
These rugged sensors are attractive because of their small size, weight, and power consumption (SWaP), as well as their tolerance of environmental variables like mechanical vibration. But the general consensus has been that high levels of radiation would modify the optical properties of their silicon, leading to incorrect readings.
So NIST, launched a program to answer those questions. The test results indicate the sensors could be customized for measuring radiation dose in both industrial applications and clinical radiotherapy. The results of its first round of testing is reported in Nature Scientific Reports.

A technical revolution in ocular surgery
Ziemer’s proprietary FEMTO LDV systems are based on a radically different technology. With their unique operating concept, the FEMTO LDV systems have already become the technology leader among all femtosecond lasers.
Microscope lens quality optics
Operating with very low pulse energy (nJ) and very short pulse width but very high pulse frequencies (> 5 MHz), the threshold for tissue disruption is reached without requiring an amplifier.
This low energy delivery has turned out to be the most relevant factor for a gentle tissue resection:
The FEMTO LDV Z Models feature a hand-piece with a highly sophisticated optical system: an optomechatronical masterpiece.
These custom made microscope lenses with high numerical aperture assure a perfect focus and ensure high precision in cutting depth:
High density pulse raster
Standard pulse rasters by conventional laser systems:
An incomplete resection may lead to tissue-bridges: the flaps cannot be easily lifted and there is more mechanical stress on the eye.
High density pulse raster by Ziemer’s FEMTO LDV systems:
The precision optics, the custom-made laser sources and a proprietary high speed scanning system generate tightly focused low-energy laser pulses in an overlapped pulse raster.
This results in a complete and smooth resection with no interstitial, un-dissected spaces andminimal complications.
The FEMTO LDV Z2, Z4, Z6 and Z8 are CE marked and FDA cleared. For some countries, availability may be restricted due to regulatory requirements; please contact Ziemer for details. Presbyopia treatments occur exclusively by a pocket creation and the implantation of a corresponding corneal inlay of a third party. Availability of related corneal inlays and implants may vary according to policy of the individual manufacturers and regulatory status in the individual countries. To comply with FDA regulations, devices for sale in the U. S. do not mention 'Presbyopia' on the panels.

EMPOWERING FLEXIBLE AND SCALABLE HIGH PERFORMANCE ARCHITECTURES WITH EMBEDDED PHOTONICS
The explosive growth in data analytics applications that rely on machine and deep learning techniques is seismically shifting the landscape of high performance architectures. Driven by these applications, system performance is increasingly bottlenecked by the energy and communications costs of interconnecting the numerous heterogeneous compute and memory resources. Recent advances in integrated silicon photonics offer the opportunity of embedding optical connectivity that directly delivers high off-chip communication bandwidth densities with low power consumption. This talk will review these advances and introduce the concept of embedded photonics for addressing data movement challenges in high-performance systems. Beyond alleviating the bandwidth and energy bottlenecks, embedded photonics can enable new disaggregated architectures that leverage the distance independence of optical transmission. I will also discuss how the envisioned modular system, interconnected by a unified photonic fabric, can be flexibly composed to create custom architectures tailored for specific applications.

I am a research scientist at Epic Games. I obtained my PhD from Carnegie Mellon University, advised by Aswin Sankaranarayanan.
My research interests are
computational photography & imaging
physics-based differentiable rendering
3D geometry and calibration
adapting painting techniques to photography
Before Ph.D., I received my M.S. in Computer Vision from Carnegie Mellon University in 2016, and B.S. in Computer Science from Rice University in 2015.
I interned at Google Daydream in 2018 and Apple Special Project Group in 2016.
My primary research interest lies in computational photography.
During my Ph.D., I worked on camera designs that can significantly minimize their size and bulk -- cameras without lenses.
I developed both novel hardware and their reconstruction algorithms to enhance the speed and quality of 3D lensless imaging.
Ultrasonically-sculpted waveguides can be used as a virtual lens to guide and focus light in transparent and scattering media. However, the images formed by such lenses are subject to a large amount of spatially-varying blur. We propose two computational deblur techinques: one straigh-forward approach using mode 0 measurements, and another more efficient approach based on Radon transform and mode 2 measurements. The computationally deblured images reveals more details from the scene behind scattering media.
Recovering images from lensless measurements are challenging because the per-pixel depth of the scene needs to be correctly identified to avoid artifacts in the reconstruction. We introduce computational focusing on lensless measurements so that we can reconstruct one depth slice of the scene at a time, and improve the speed as well as the quality of reconstruction.
Instead of a planar sensor with a rigidly attached modulation element, we propose a lensless imager on a spherical surface, where all pixels share the same angular response profile.
The implications of our design is that lensless imaging can be enabled for curved and flexible surfaces, thereby opening up a new set of application domains.

Light brightness and color scales
Within the lighting industry there are specific terms regarding the quality of the light emitted from a light bulb and how to measure the brightness. Understanding these terms can be helpful when trying to decide which lighting fixtures and light bulbs will be the right ones for a certain space and atmosphere. Below is a description of the most relevant terms regarding the color and brightness of light bulbs.
Lumens indicates how bright the light is, simply, the higher the lumens the brighter the light will be. When calculating the number of lumens that is needed for lighting up a space it is important to consider how large the area is (m2) and what the purpose of the area is. For example, ambient lighting for a 20 m2 living room should be around 1000 Lumens. There are specific calculators to support you in choosing the right amount of Lumens.
Lumens indicates how bright the light is.
Kelvin is a measurement scale used to measure a light bulb’s specific color temperature. The higher the number is on the Kelvin scale the cooler and more bluish white the light is. In normal household fixtures the color temperature will most likely range between 2700K and 3500K. Understanding the different ranges of the Kelvin scale helps to choose the right fixture for the area in question. For example, choose a color temperature between 2000K – 3000K for living areas in a house such as bedrooms and dining rooms but go for higher color temperatures in kitchen areas where brighter light is more useful (3000K-4500K). If a more ambient setting is wished for that replicates candle-light, then light bulbs with less than 2000K are preferable. So, the higher the Kelvin scale goes the cooler the light looks. To mimic daylight and have a high level of light go for between 5000-6000K.
CRI stands for color rendering index which simply means a measurement of how true the color of an object is under a bulb’s light. The CRI scale ranges from 0 – 100 with 100 having the highest level of color rendering ability. Secto Design lamps have a CRI of about Ra80 to provide a high enough level of CRI but to also allow for warm and pleasant lighting.
The unit used to measure CRI (Color Rendering Index), the higher the value the more natural the color of the objects placed under the light will be.
Light distribution curve of Kontro 6000.
Photometric curves illustrate how the light beam will take shape, for example, is the beam going to be narrow or wide, symmetric or asymmetric etc. This is important to understand how much light one will have from a lamp that shines on, for example, a dining room table.


Once you have your prescription and chosen your frame, our dispensing team that consists of qualified dispensing opticians and skilled optical advisor’s who are highly trained in assessing individual customer requirements, will take you through our range of bespoke and custom-fit lenses, which features single vision, bifocals or varifocal lenses.
We can provide lenses that are thin, lightweight, scratch resistant and anti-reflective, and if you are sensitive to the sun’s glare, we can provide you with light sensitive lenses (Transitions) that change colour according to light conditions.
Hoya and Kodak manufacture the majority of our lenses, by using their expertise and precision in manufacturing techniques, you are guaranteed a high quality lens.
By having an anti reflection coating on your lenses, you will dramatically reduce glare from driving at night, computer screens, and cosmetically improve the look of your glasses. Why not upgrade this with a hydrophobic and oleophobic coating, allowing water to run off the lens easily, and to reject grease and general dirt, making your lenses much easier to clean? Call in for information on View Protect Hi-Vision Long Life Coatings.
We have a wide variety of different colour tints for all lenses, from gradual tints to full tints. Brown, grey and green are best for sunglasses. Blue, pink and yellow are also available.
Polarised lenses dramatically reduce glare, improving your vision in very sunny conditions. A polarised lens is ideal for driving on wet roads or for sports such as fishing, skiing and sailing.
Changing light conditions occur frequently, and for people who are sensitive to glare, transition lenses are the perfect solution. Transition lenses adapt to light conditions, giving you comfortable vision in bright light. Indoors, the lenses are virtually clear, outside they quickly darken in sunlight, giving you 100% UV protection.
A scratch resistant coating or hard coat protects the lens surface from scratches, so your lenses are less likely to be damaged. The extra protection prolongs the life of the lens whilst providing clearer vision.
Thin & lite lenses are a great solution for people with higher prescriptions, allowing greater comfort and an enhanced cosmetic appearance, enabling you to have a wider range of frames to choose from.
Varifocals, or progressive lenses as they are sometimes referred to, combine both distance and reading prescriptions into one lens, giving comfortable, sharp vision at all distances, allowing the wearer the convenience of one pair of glasses for all purposes.
There are various designs of varifocals on the market, and the technology behind the lenses is constantly improving. The new generation of varifocal lenses is known as freeform technology. The freeform process allows lens designers to calculate and manufacture the most accurate lens possible. Wearers benefit from lenses that have the highest degree of optical accuracy and a considerably wider focused viewing area.
We are pleased to offer you our own brand Free Form Varifocal Technology. Please call in for more information or if you require a Varifocal consultation please contact your nearest branch for a consultation.

The sunglasses of these glasses are polarized and polycarbonate. They ensure you a high protection against the sun’s rays.
Polarized sunglasses, what is it?
The light is reflected on the shiny surfaces: sea, road … This phenomenon generates parasitic reflections that cause discomfort and visual inaccuracy, with or without glasses. A polarizing lens has a filter that suppresses these parasitic reflections. Polarizing glass blocks polarized light and only passes light carrying information. Thus, it improves visual acuity by allowing a better reading of the information that reaches the eye.
What is polycarbonate lenses?
Polycarbonate is the latest generation material that is replacing more and more glass and plastic. Polycarbonate is a synthetic material that has the peculiarities of being very resistant to shocks and very light. It filters 100% of UV.

Calibrated for Quantitative Accuracy
Our ORCA-Flash4.0 cameras have always provided the advantage of low camera noise. In quantitative applications, like single molecule imaging and super resolution microscopy imaging, fully understanding camera noise is also important. Every ORCA-Flash4.0 V3 is carefully calibrated… as a precision instrument must be. Our attention to this detail delivers outstanding linearity, especially at low light, and offers improved photo response non-uniformity (PRNU) and dark signal non-uniformity (DSNU) to minimize pixel differences and reduce fixed pattern noise. Each camera ships with a certificate providing the read noise and photoelectron conversion factor specific for that camera.
Flexibility for Customized Data Control
Like its predecessors, each ORCA-Flash4.0 V3 is capable of both USB 3.0 or Camera Link output. In addition, the ORCAFlash4.0 V3 offers data reduction through user-controllable look up tables (LUT) for 12 or 8-bit output. These two choices, combined with region of interest selection enable you to fine tune acquisition speed and image data requirements.
Patented Tools for Advanced Imaging
The ORCA-Flash4.0 V3 includes our now patented, Lightsheet Readout Mode which takes advantage of sCMOS rolling shutter readout to enhance the quality of lightsheet images.
When paired with our W-VIEW GEMINI image splitting optics, a single ORCA-Flash4.0 V3 camera becomes a powerful dual wavelength imaging device. In “W-VIEW Mode,” each half of the sensor can be exposed independently, facilitating balanced dual color imaging with a single camera. And this feature can be combined with the new and patented “Dual Lightsheet Mode” making simultaneous dual wavelength lightsheet microscopy a reality. And finally, the ORCA-Flash4.0 V3 is the perfect complement to our new W-VIEW GEMINI-2C dual camera, super resolution-quality, image splitting optics.
Focus on the Relevant Data
Our new “Enhanced Visualization Mode” was designed to help answer the question “Can I see it?” Many low light experiments, especially those that were previously imaged using EM-CCDs are now routinely accomplished—with better signal to noise, faster speeds and at far less expense—by sCMOS cameras. However, we sometimes miss the visual punchiness of EM-CCD images. Enhanced Visualization Mode pops the contrast of the displayed image, while
saving the sCMOS raw image data to disk.
And sometimes our innate tendency to seek contrast can be a distraction. Even a few hot pixels in a time lapse or tracking experiment can divert our attention or our analysis from the real data. Enter our multi-level, user-selectable, hot pixel reduction. By applying a series of increasingly aggressive algorithms to detect noisy pixels, you can choose to eliminate these small but distracting elements. And since nobody appreciates having their data unexpectedly modified, the default setting for this hot pixel correction is off when you power up the camera.
Powerful Triggering for Synchronization
Joining a full complement of sophisticated triggering routines, our new Master Pulse timing generator allows the ORCA-Flash4.0 V3 to truly run the experiment. Performing functions that previously would have required an external pulse generator the ORCA-Flash4.0 V3’s Master Pulse has flexible timing delays built in. Powerful synchronization of multiple cameras and devices just became a lot simpler.

In this paper, we present a method she has been working on that makes 3D objects appear differently under different viewpoints. We accomplish this by 3D printing lenticular lenses across the curved surface of objects. By calculating the lens distribution and the corresponding surface color patterns, we can determine which appearance is shown to the user at each viewpoint. We built a 3D editor that takes as input the 3D model, and the visual appearances, i.e. images, to show at different viewpoints. Our 3D editor then calculates the corresponding lens placements and underlying color pattern. On export, the user can use ray tracing to live preview the resulting appearance from each angle. The 3D model, color pattern, and lenses are then 3D printed in one pass on a multi-material 3D printer to create the final 3D object.

This week we’ve received an interesting package by Intel USA with the very new Intel RealSense F200 camera. We are really surpised how small the camera is. The camera is a longer range peripheral 3D camera, perfect for sensing the environment (for Windows and Android tablets, 2-in-1s, and more). The “R” in the cameras model name stands for “Rear” since it is best suitable using it while the camera is facing away from you (instead of the F200 camera which is facing frontally).
The camera has a range of 3-4 metres (inside a room) and a larger range out of doors. The key features of the camera are
- 3D recording (faces, people, environment)
- Depth camera
- Face tracking and face recognition
- Measuring in general
We are now waiting for the SDK to start our first projects with this tiny piece of high-tech.


2 Items You Do Not Have Information With Respect To LASIK Eye TreatmentsThe eye can be taken a look at with relative ease regarding both its function and its structure. A functional evaluation consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be tested in numerous ways. The patient may be asked to determine illuminated letter or items of differing sizes on what is known as the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in a number of methods. Stress within the eyeball is determined by a "tonometer." In specific diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye problem might have other problems also. Often other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can inform the doctor and the client to troubles in some disruptions of other parts of the body even prior to other symptoms provide themselves.
One's dependence on sight is highlighted when one faces a possible or short-lived long-term loss of this important sense. Hence, when corrective steps are sought, certain forms of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are bothered with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." look here Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this type of surgery, one's vision is fixed completely.
With LASIK eye surgery, the refractive mistakes in the cornea are completely changed. This can be done using an "excimer laser."
The primary function of this surgical treatment is to create a threadlike, rounded "flap" in the cornea utilizing a blade referred to as "microkeratome." In a series find more information of unfolding and laser processing, the cornea is lastly reformed, permitting better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that individuals should know. Most likely, the main factor why this type of eye surgery has actually ended up being well accepted is since the majority of its cases had achieved success.
Nevertheless, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation used to the most delicate part of the eye
Because LASIK eye surgery involves the operation of the retina, which is among the most delicate parts of the eye, most individuals say that the operation can be extremely risky.
Simply puts, a simple error might almost trigger an person's lifetime blindness. It is essential to think about numerous factors prior to deciding whether LASIK eye surgery is the best corrective measure one has to go through.
2. It is not a best treatment
LASIK eye surgical treatment may correct your vision however it does not always imply that it can offer you a best vision. Even if analytical reports reveal that 70% of the patients might have 20/20 vision, this does not always imply they have perfect vision.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not constantly be the perfect eye surgery the way many people see it
On the other hand, the examination of the structural part of the eye may be made in numerous ways. It needs to be well remembered that a patient with an eye problem might have other issues. Often other physical conditions are main and impact the eye as a consequence. The appearance of the eye can inform the doctor and the client to troubles in some disturbances of other parts of the body even prior to other signs provide themselves.
Like its tangible counterpart, LASIK eye surgical treatment is another kind of vision correction.

Two Factors You Do Not Recognize About LASIK Eye TreatmentsThe eye can be examined with relative ease as to both its function and its structure. A functional examination consists of the ability to move in the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be evaluated in a number of methods. The patient might be asked to identify illuminated letter or things of varying sizes on exactly what is referred to as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in several methods. Stress within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased significantly.
However, it needs to be well bore in mind that a patient with an eye problem may have other problems too. Typically other physical conditions are primary and impact the eye as a effect. The look of the eye can inform the doctor and the client to problems in some disruptions of other parts of the body even before other symptoms provide themselves.
One's dependence on sight is emphasized when one faces a possible or momentary irreversible loss of this essential sense. When restorative procedures are sought, particular kinds of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this type of surgical treatment, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the cornea are permanently changed. This can be done utilizing an "excimer laser."
The main purpose of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea utilizing a blade understood as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, permitting better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people must understand. Probably, the primary reason why this type of eye surgical treatment has become well accepted is due to the fact that many of its cases had been effective.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most delicate part of the eye
Since LASIK eye surgical treatment involves the operation of the retina, which is among the most delicate portions of the eye, many people say that the operation can be extremely dangerous.
Simply puts, a basic error might almost cause an person's life time loss of sight. It is important to consider lots of factors before choosing whether LASIK eye surgery is the right corrective procedure one has to undergo.
2. It is not a perfect procedure
LASIK eye surgery may correct your vision but it does not necessarily suggest that it helpful hints can provide you a best vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily mean they have perfect vision as well.
Offered all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the ideal eye surgery the way many people view it
Conversely, the evaluation of the structural part of the eye may be made in several methods. It needs to be well kept in mind that a patient with an eye problem might have other problems. Often other physical conditions are main and affect the eye as a consequence. The look of the eye can alert the client and the doctor to problems in some disturbances of other parts of the body even before other signs provide themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another type of helpful resources vision correction.

The ratio of the subject size on the film plane (or sensor plane) to the actual subject size is known as the reproduction ratio. Likewise, a macro lens is classically a lens capable of reproduction ratios of at least 1:1, although it often refers to any lens with a large reproduction ratio, despite rarely exceeding 1:1.
Apart from technical photography and film-based processes, where the size of the image on the negative or image sensor is the subject of discussion, the finished print or on-screen image more commonly lends a photograph its macro status. For example, when producing a 6×4 inch (15×10 cm) print using 135 format (3.6×2.4 cm) film or sensor, a life-size result is possible with a lens having only a 1:4 reproduction ratio.
Ordinary lenses can be used for macro photography by using a "reversing ring." This ring attaches to the filter thread on the front of a lens and makes it possible to attach the lens in reverse. Excellent quality results up to 4x life-size magnification are possible. For cameras with all-electronic communications between the lens and the camera body specialty reversing rings are available which preserve these communications. When used with extension tubes or bellows, a highly versatile, true macro (greater than life size) system can be assembled. Since non-macro lenses are optimized for small reproduction ratios, reversing the lens allows it to be used for reciprocally high ratios.

Extending the distance between the lens and the film or sensor, by inserting either extension tubes or a continuously adjustable bellows, is another equipment option for macro photography. The further the lens is from the film or sensor, the closer the focusing distance, the greater the magnification, and the darker the image given the same aperture. Tubes of various lengths can be stacked, decreasing lens-to-subject distance and increasing magnification. Bellows or tubes eliminate infinity focus.

Photoacoustic Detection of Trace Contaminants
When pulses of light energy absorbed by a sample are converted rapidly into heat, a sound wave can be produced through periodic thermal expansion. The intensity of the sound wave directly relates to the amount of absorber in the sample. Since the signal is produced directly from the absorber, as opposed to inferring it from the absence of signal (as in absorbance spectroscopy), it is well-suited for measuring trace contaminants.
Typically, this sound wave is recorded with a sensitive microphone. Impressive detection limits have been obtained, making photoacoustic techniques popular in trace gas detection. In our lab, we use a fiber Fabry-Perot (FFP) cavity in conjunction with the Pound-Drever-Hall (PDH) technique as an optical microphone to record the sound wave.
We have previously used this method to detect analytes in microfluidic devices and in capillary electrophoresis. Recently we use acoustic resonators such as a wineglass or cantilever beams to further amplify the signal.

In the world of thermal imaging, a thermal scope is a gadget used for thermal discovery. By describing this as a thermal cam, it is suggested to provide a computerized means of identifying temperature levels. Infrared light is the various other major element of this technology. There are several differences in between the two though, including the techniques of discovery and also the equipment required for this application. It is made use of in the military as well as industrial sectors for every little thing from tool views to security devices. On a somewhat much deeper level, a thermal scope in fact receives a thermal picture with a lens on its surface. The lens sends this thermal photo to a detector, which lies before the objective. The detector utilizes a high resolution scanner to identify the pictures which are after that presented on a computer screen. This screen supplies the individual with a high resolution picture of the target items and thus it is capable of giving a clear as well as crisp photo that is usually much easier to translate than a normal cam. By checking the screen, the thermal scope likewise spots any kind of roaming light that may have been reflected off the target things and this is utilized for more analysis on the image. The image created by the thermal extent is in real time and is conveniently flexible relying on the needs of the customer. Normally, a user will make use of a small laser projector to brighten the target area as well as the scanner and also the objective lens at the same time. In doing so, both the scanner and also the objective lens are scanned at the same time. This check of the whole location produces a hd picture as well as is therefore a form of optical zoom. Other optical zoom techniques include electronic zoom and also monocular zoom. Optical zoom is often required in thermal extents due to the fact that the distance to the target beyond of the rangefinder is a lot bigger than the range to the target on the contrary side of the rangefinder. If the rangefinder reveals the target as being at infinity, after that the thermal scope would reveal the target at all ranges up to infinity. Hence, thermal extent may not be able to give a clear photo of the target at close range. This situation will arise if one needs to make a chance at lengthy variety while the optical zoom holds. A thermal extent can eliminate this problem by giving a much clearer picture of the target at every suitable distance. Thermal tool sights are made use of for searching by law enforcement agencies for the discovery of hidden weapons. It is ideal for use by these companies when it pertains to night procedures. For instance, when handling lawbreakers that are hiding behind items such as trees as well as structures, it makes excellent feeling to use this modern technology. It makes it possible for seekers to eliminate a possible risk without needlessly putting their lives in jeopardy. Night vision ranges and also thermal scope can both be adjusted to various sizes allowing the customer to concentrate on a certain section of the electro-magnetic spectrum for better precision. Some ranges likewise have features such as crosshairs, which makes focusing on a pet or body less complicated. However, it is advised that a person contrasts the different versions and also scopes before opting for any type of particular kind of device. It is additionally recommended to examine whether the thermal range has any evening vision abilities. While hunting during evening, thermal scopes are the most ideal devices.

- Gobe CPL Filter Review
- What are Gobe filters?
- Final Remarks
Gobe UV Filters Review
Let’s start our Gobe filter reviews with the most basic and widely used Gobe UV filters.
UV filters are no longer used to take care of the ultraviolet light.
Rather, they are used as protective filters of our lens glass by acting as a barrier to protect our lenses from any debris, twigs, rocks, or sticky fingers.
You can use these filters for any – Canon, Sony, Nikon lens other camera lenses you have.
Gobe UV Filters are perfect for outdoor shoots to protect your lenses from any damage that might happen on-field.
Gobe’s German and Japanese glass filters are phenomenal as they do not affect the quality of the photos in the slightest. They are incredibly durable and can withstand everything you can imagine needing them to.
Gobe UV Schott 16-Layer Ultra Violet Filter
The Gobe UV Schott filter is nicely engineered with a reassuringly crisp gnarling and thin profile and contains a multi-resistant coated ultraviolet filter, which helps reduce light reflections and protects your lens from any kind of dust, moisture, and scratches.
Hence, you can adjust the color contrast and saturation of images. The 16-layer multi-coating provides maximum flare protection and the UV filter is highly effective for preventing UV lights from entering your lens and reduces blurring.
It also provides extra assurance in case of accidental drops. The high-quality German Schott B270 glass provides top-level light transmittance, increased optical clarity, and color fidelity. It comes in beautiful packaging with a lens cloth given with each filter.
Pros & Cons
Gobe ND Filters Review
The main Gobe neutral density filters that are a must to try:
The good news?
You can buy a kit which contains all of them.
These variable ND filters allow you to slow scenes down such as water and create dramatic effects, with limited to No-color-cast.
That’s exactly what you want with an ND filter.
The fixed ND filters are my personal favorite as they are built to perform a specific task such as cutting out a specific amount of light but that doesn’t make the variable ND’s any less favourite because they also do a fantastic job.
Gobe Lens Filter Kit containing ND8, ND64, ND1000
While we’ve never really been fans of variable ND filters mainly because they were a little too pricey but Gobe has upped its game with their ND filters that are the highest standards in quality while remaining reasonably priced.
Talking about the Gobe Lens Filter kit, This excellent camera lens filter set includes a lens cap, a cap keeper, UV and CPL filter NDs including an ND8 (3 stop), ND64 (6 stop), and ND1000 (10 stop) filters and a filter case.
High-quality, Japanese optical glass with 16-layer nano-coating that provides neutral color balance, reduces lens flare, removes ghosting, and projects against scratches, dirt, and grime. You can mount these filters on your camera lens permanently because these are high-quality filters and create a minimum impact on the quality of the image.
Pros & Cons
Gobe NDX Variable ND Filter
Instead of buying a lot of fixed ND filters, you can choose a variable ND filter.
Gobe NDX variable ND lens filter comes with a rotating ring between ND2 and ND400 and cuts out a fixed amount of light intake from 1 to 8.66 f-stops without affecting color balance which easily makes it one of the most versatile and easy-to-use options available in the market right now.
It is designed with a premium Japanese optical glass with 8-layer nano-coating that helps reduce vignetting, provides a neutral color balancing, and removes ghosting when you are shooting from wide angles.
It also comes with a round metal case that is slightly larger than the filter( absolutely better than the crappy plastic cases provided by other filter suppliers) and a Gobe cleaning cloth
Excellent value for money, Gobe NDX Variable ND Lens Filter is well made and will bring the color and clarity back to your outdoor videos and images so you can create stronger depth-of-field and motion blur effects.
Pros & Cons
Gobe CPL Filter Review
The effect given by their CPL filters in post-processing is second-to-none.
They can take the glare off of water if used at the right angles. CPL filters also do a phenomenal job of boosting contrast and colors in other landscapes as well.
Gobe Circular Polarizing (CPL) Filter (3Peak)
The Gobe Circular Polarizing (CPL) Lens Filter comes from one of the most well-regarded filter makers Gobe, known for its best quality filters in the most reasonable pricing, with easy gripping on the outer rim and more than one thread sizes to choose from.
It brings premium German Schott B270 optical glass and 16 layers of nano-coating for better light transmission and reduction of flaring and ghosting. The surface of the CPL filter is also stain-resistant and water-repellent. The consciously designed magnalium rims of this filter are double-threaded and slim to avoid vignetting.
This filter is thin enough to fit nicely on a wide-angle lens without any trouble. The company also promises to plant five trees for each filter you buy. Low cost, high performance, reliable company, 5 new trees in the world – that’s what makes it a great offer.
Pros & Cons
What are Gobe filters?
The Gobe is a project of two Australian guys who took a leave from their studies to travel around the world taking pictures and having fun.
They came up with the idea of producing lens filters and saving the planet at the same time upon observing the dramatic deforestation in some parts of the world and so their venture began.
What intrigued me about their filters was that for every filter you buy, you help plant 5 trees in some parts of the world.
Their filters are available in three different qualities:
Lenses, are one of the most important parts of the camera gear as they can make or break the deal depending on the quality. You should always look for lens filters that not only accentuate shots but also protect the lens.
With hundreds and thousands of pricy lens filters out there, I wanted to go for something that gives a good quality-to-price ratio so I decided to give this new kid in the block a try. And Gobe filters are worth the shot.
High quality, sensible pricing, and low profile but sincere environmental policy, you won’t get a more suitable filter option at such a low price.
