The colors of the rainbow are all around us, but so are hues that most of us can't see, including ultraviolet — a wavelength that eludes many humans but, surprisingly, many animals can perceive.

An invisible band of radiation with wavelengths from 400 to 10 nm, ultraviolet (UV) light starts at the end of visible light and ends at the beginning of X-rays. The primary source of ultraviolet ...

I recently received a question about the use of technology in ecological research, which led to a discussion about ...

Coherent (Santa Clara, California, USA) has not announced any new DPSS-UV products recently, but has a wide range of both CW and pulsed lasers with wavelengths of 266 nm or 355 nm and a wide range ...

Both of these rely on the deep-UV emission wavelength of 193 nm, with semiconductor chip manufacturing capitalizing on the optical resolution of excimer lasers, and refractive eye surgery on its ...

Biofluorescent creatures generate their glow with structures that absorb high-energy wavelengths of light, such as UV, violet or blue, then emit the light in a lower-energy wavelength. Researchers ...
