Not all red light is the same. 660nm boosts collagen; 850nm reaches joints. This guide breaks down which wavelength works for ...

We often feel that we are "on the same wavelength" with one another, but can science identify and engineer this phenomenon?

A specific wavelength of ultraviolet (UV) light is not only extremely effective at killing the virus which causes COVID-19, but is also safer for use in public spaces, finds new CU Boulder research.

Engineers have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing and communication systems.

KYOTO, Japan--(BUSINESS WIRE)--Kyocera Corporation (President: Hideo Tanimoto; “Kyocera”)(TOKYO: 6971) announced that it has developed a new meta-lens that uses metasurface-based optical control ...

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 ...
