Nanowire lens can reconfigure its imaging properties
New type of X-ray lens: Lamellar lens prototype has been successfully tested
Researchers have taken an important step towards developing a new X-ray lens made of diamond. A team of scientists from the Technische Universität (TU) Dresden and Technische Universität Chemnitz as well ...
Thermal vision: Graphene light detector first to span infrared spectrum
The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens.
Google contact lens could be option for diabetics
Brian Otis gingerly holds what looks like a typical contact lens on his index finger. Look closer. Sandwiched in this lens are two twinkling glitter-specks loaded with tens of thousands of miniaturized transistors. ...

Integral 3D TV system projects a promising future (w/ Video)
Nanodiamond-embedded contact lenses may improve glaucoma treatment
(Phys.org) —By 2020, nearly 80 million people are expected to have glaucoma, a disorder of the eye that, if left untreated, can damage the optic nerve and eventually lead to blindness.
Device turns flat surface into spherical antenna
By depositing an array of tiny, metallic, U-shaped structures onto a dielectric material, a team of researchers in China has created a new artificial surface that can bend and focus electromagnetic waves ...
Lens combines human and insect vision to focus wide-angle views
A lens invented at The Ohio State University combines the focusing ability of a human eye with the wide-angle view of an insect eye to capture images with depth.
A breakthrough in superlens development: Cheap, simple lens to let us see a single virus
A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in ...
Telescopic contact lens could improve eyesight for the visually impaired
(Phys.org) —A team of engineers has designed a telescopic contact lens that can switch between normal and magnified vision by using slightly modified off-the-shelf 3D television glasses. The researchers, ...
Multiview 3-D photography made simple
Computational photography is the use of clever light-gathering tricks and sophisticated algorithms to extract more information from the visual environment than traditional cameras can.
New metamaterial lens focuses radio waves: Device could improve satellite and molecular imaging
In many respects, metamaterials are supernatural. These manmade materials, with their intricately designed structures, bend electromagnetic waves in ways that are impossible for materials found in nature. ...
The better to see you with: Scientists build record-setting metamaterial flat lens
For the first time, scientists working at the National Institute of Standards and Technology have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that ...
