Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength ...

For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into ... where space is ...

such as on aircraft, satellites and space-based telescopes. If you’ve ever used a magnifying glass, you know that lenses bend light to make objects appear larger. The thicker and heavier the ...

Naval aviators know that traffic light as the Improved Fresnel Lens Optical Landing System. A pilot uses IFLOLS to discern his glide slope—the angle at which aircraft descend and land—by ...

Scientists have created contact lenses that they claim allow people to see in the dark with the help of infrared light, an invention that could allow colorblind people to see colors again ...

Lenses are the most widely used optical devices. Camera lens or objectives, for example, produce a sharp photo or video by ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely ...
