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 ...

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 ...

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 ...

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.
