Identifying sources of light plays an important role in the development of many photonic technologies, such as lidar, remote sensing, and microscopy. Traditionally, identifying light sources as ...

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 ...

Light pollution is the bane of stargazers, which is why you need to get out of the city to make the best use of your telescope. However, even in the middle of nowhere, your observations might still be ...

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 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 ...

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 ...
