Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

The use of alternative light sources and ultra violet lighting has changed and improved drastically over the last few years. The concept, however, remains the same as the purpose of alternative light ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

The Advanced Light Source (ALS), a scientific user facility at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), has received federal approval to start construction on ...

It’s inevitable: Fabrics and artwork will fade over time, but that fading can slow down with the right care. To help your clients take better care of their new fabrics and artworks, Lighting Doctor ...

With all the buzz about how the output spectrum of LED lighting can be varied for applications like street lighting, human-centric lighting, and horticultural lighting, the question occurs: how is the ...

In materials science an X-ray source that is hard and bright can open the door to a wealth of detail. At Diamond Light Source X-ray beams with wavelengths of 0.1–0.2 nm outshine the Sun by a factor of ...
