Researchers have developed a thin lens with a continuously tunable focal length. The new lens could one day make visual fatigue from augmented and virtual reality (AR/VR) devices a thing of the past. ...

Scientists are reporting development of a revolutionary new lens—flat, distortion-free, so small that more than 1,500 would fit across the width of a human hair—capable in the future of replacing ...

A new type of flat, ultrathin lens designed to be free of chromatic aberrations has been developed by researchers in the US. The device has a variety of potential applications, from ultralight imaging ...

Caltech engineers have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it ...

A proper everyday augmented reality experience is a long way off, but at CES 2023, an optics company called Lumus may just be offering a glimpse of what mainstream AR could look like. And the emphasis ...

There’s a little trick you can do to capture macro photography shots on your smartphone, using nothing more than a drop of water. The idea is the water acts as a very rudimentary lens, which has a ...

Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.
