Contact lenses get pretty thin nowadays, but they’ve got nothing on a new lens from scientists at Stanford and the University of Amsterdam. The team has created the world’s thinnest lens, measuring ...

Physicists in the US have made the first ultrathin flat lens. Thanks to its flatness, the device eliminates optical aberrations that occur in conventional lenses with spherical surfaces. As a result, ...

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 ...

An important aspect of the quest for higher-sensitivity detectors is the volume of the active semiconductor material that composes the photodetector. Noise-generation mechanisms scale with the ...
