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 ...

An ultrathin and flat "metalens" could someday replace curved (convex) lenses typically used in microscopes, telescopes, cameras, smartphones and other devices. Developed by engineers from the Harvard ...

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 ...

Craig Marshall continues his series on classic Contax stills lenses that make for great video on modern cameras. This time it's the turn of the Zeiss ‘Contax’ Planar 50mm f/1.7. Weekends at RedShark ...

Fig. 1 Neural array imaging system and its principle behind its ability to break the trade-off between aperture size, ffeld of view, and imaging quality. (a) The system consists of a metalens array, a ...

Scientists have developed the first flat lens for immersion microscopy. This lens, which can be designed for any liquid, may provide a cost-effective and easy-to-manufacture alternative to the ...

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.
