Researchers have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light -- covering the whole range of colors from red to blue. The lens can resolve ...

Ji Chen’s team from Southeast University proposes a bioinspired motion detector based on planar metalens arrays. It realizes an ultra-wide 135° field of view and achieves high-precision perception of ...

Resolving the polarization of light scattered from many biological structures is an important part of analyzing their nature and function. But doing so has previously required a complicated optical ...

Researchers developed a new ultra-thin planar (flat) "metalens" that can potentially replace the stacked, bulky lenses used in telescopes, microscopes, smartphones, cameras and other gadgets. Despite ...

The Sony Full-Frame Planar T FE 50mm F/1.4 ZA Prime Lens attached to an A7R Mark II camera body. Stan Horaczek Sony seems to be on a bit of a new 50mm lens kick lately. Not long ago we met the new ...

Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto lenses so long.
