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 ...

The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much simpler to make. The scientists hope the breakthrough could lead to cheaper ...

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 ...

Synchrotron radiation facilities can deliver powerful continuum radiation from the microwave (specifically harmonics of the driving RF field) to the X-ray spectral regions. These are produced by high ...

For hundreds of a millions of years, the universe existed in the dark ages—an epoch when only primordial gasses existed. Then, a period of reionization, cleared away this foggy existence an introduced ...

For a little over two thousand years, the primary light sources after the sun had set were oil lamps and candles. This was well before the age of fossil fuels, so these oil lamps were often fueled ...

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 ...
