Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...

In a lab in Zurich, scientists have built something that, at first glance, shouldn’t be possible. When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it ...

In recent years, the world of optics has undergone a major shift. New research shows how light can be bent, focused, and even changed in color using structures so small they’re invisible to the eye.

The Model 228 lens from Resolve Optics has become an industry standard for Reflected Ultraviolet Imaging Systems (RUVIS) used to detect fingerprints or bloodstains undiscovered during an initial crime ...

Illinois researchers developed a spherical lens that allows light coming into the lens from any direction to be focused into a very small spot on the surface of the lens exactly opposite the input ...
