Precision optics hot off the press
Optical lenses have already become a mass product. They focus the bar code laser at the supermarket checkout, record pictures in cameras and mobile phones and control the transmission of data along fiber optic telecommunications cables. Automated production processes help to meet this ever-increasing demand for lenses. While simple plastic lenses... view more... (2003-04-24)
First human trial of antibacterial contact lens
Biotechnology company Biosignal Ltd and the Institute for Eye Research have received ethics approval for the first human clinical trial of an antibacterial extended-wear contact lens. view more (2006-06-29)
Plasmonic Whispering Gallery Microcavity Paves the Way to Future Nanolasers
The principle behind whispering galleries - where words spoken softly beneath a domed ceiling or in a vault can be clearly heard on the opposite side of the chamber - has been used to achieve what could prove to be a significant breakthrough in the miniaturization of lasers. Ultrasmall lasers, i.e., nanoscale, promise a wide variety of intriguing... view more... (2009-01-26)
Contact lenses and catapults - recognising the achievements of physics students
Three outstanding students have won prizes from the Institute of Physics for their course work in Advancing Physics, the Institute’s new physics A level course. Dr Julia King, the Institute’s Chief Executive, presented the students with their prizes at a ceremony organised by the OCR examining board in London on 28 November. Institute... view more...

Scientists demonstrate highly directional semiconductor lasers
Applied scientists at Harvard University in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, highly directional semiconductor lasers with a much smaller beam divergence than conventional ones. The innovation opens the door to a wide range of applications in photonics and... view more... (2008-07-28)
UCF, Holochip Corp. announce global licensing agreement for zoom lens patents
The University of Central Florida has signed a licensing agreement with Holochip Corp. for a portfolio of technologies that will allow zoom lenses, such as those used in digital cameras and camera phones, to be manufactured at a dramatically smaller size without compromising clarity. view more (2007-07-23)
'Smart' sunglasses and goggles let users adjust shade and color
Imagine a single pair of glasses with lenses that can be transparent or dark, and in shades of yellow, green or purple, all on command. A new lens with chameleon powers promises to dramatically improve sunglasses' function. view more (2007-03-28)
Mini-beamer in a cell phone or PDA
A summer barbecue by the lake - as the sausages sizzle on the grill some of the party would like to watch the soccer on TV. Today, a choice has to be made whether to stay by the lake or watch the match on a big public screen or the TV set at home. view more (2009-06-25)
Perfect image without metamaterials ... and a reprieve for silicon chips
Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd directions to create, among other tricks of the light, the illusion of invisibility. view more (2009-09-29)
UAB Tear Research Focused on Contact Lens Risks, Benefit
Contact lenses are great for sight, but do they have an impact on general eye health? Researchers at the University of Alabama at Birmingham (UAB) School of Optometry are working to answer that question by analyzing tears. view more (2009-05-07)
Can you see me now? Flexible photodetectors could help sharpen photos
Distorted cell-phone photos and big, clunky telephoto lenses could be things of the past. University of Wisconsin-Madison Electrical and Computer Engineering Associate Professor Zhenqiang (Jack) Ma and colleagues have developed a flexible light-sensitive material that could revolutionize photography and other imaging technologies. view more (2009-01-14)
'Gecko vision': Key to the multifocal contact lens of the future?
Nocturnal geckos are among the very few living creatures able to see colors at night, and scientists' discovery of series of distinct concentric zones may lead to insight into better cameras and contact lenses. view more (2009-05-08)
Engineers demonstrate a new type of optical tweezer
Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) demonstrated a new type of optical tweezer with the potential to make biological and microfluidic force measurements in integrated systems such as microfluidic chips. view more (2008-02-26)
Measuring in 3-D
Today, complex optical free-form geometries are used primarily in car headlamps and in optics for cameras and digital projectors. These optical components are expensive to manufacture and to test. view more (2008-04-17)
Impaired vision common in US
A new report estimates that approximately 14 million people aged 12 years and older in the U.S. have vision impairment, of which more than 80 percent could be improved with the use of corrective lenses. view more (2006-05-10)
Kiwi astronomers help find icy 'Super Earth' - Life in space discovery a step closer
By designing a variant of an astronomical technique proposed by Einstein, researchers from The University of Auckland and Massey University, together with astronomers from Auckland's Stardome Observatory, have found evidence for a new icy "Super Earth". view more (2006-03-15)
Harvard University engineers demonstrate laser nanoantenna
Engineers and applied scientists from Harvard University have demonstrated a new photonic device with a wide range of potential commercial applications, including dramatically higher capacity for optical data storage. view more (2006-09-07)
Metamaterials with new electromagnetic properties
The development of new types of artificial materials, known as "metamaterials" and with electromagnetic properties not found in nature, is the aim of the Metamorphose Excellence European Network, of which the Public University of Navarre forms part, together with twenty-one other research institutions from 13 European countries. view more (2004-03-25)
Contact lenses with circuits, lights a possible platform for superhuman vision
Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Off the screen, virtual displays have been proposed for more practical purposes -- visual aids to help vision-impaired people, holographic driving control panels and... view more... (2008-01-18)
Contact lens wearers at risk from blinding infection
Some 2.2 million people wear contact lenses in England, with 900,000 alone in the southeast. Given the growing popularity in fashion contact lenses for night-clubbers, and for people who want a temporary change of eye colour, there needs to be greater awareness about the risks involved when people fail to clean their lenses properly. Dr Naveed... view more... (2003-11-03)
