The Spectrum UV from ASP Inc. is a unique, multi beam-color tactical flashlight. In addition to its primary white light, it offers red, blue and UV beams, as well as a low level ...

Scientists divide the UV spectrum into three classes: UV-A, UV-B and UV-C. UV-A radiation is closest to the visible spectrum and has the lowest energy while UV-C is farthest from visible light and ...

Some people can see much more of the UV light spectrum, however. Up until the 1980s , cataract surgery involved removing the cloudy lens from the eye and not implanting a replacement, so people ...

A particular spectrum of ultraviolet light, far UV-C, “efficiently inactivates bacteria without harm to exposed mammalian skin,” according to a study published in Nature.

The UV Index provides a measure of the sun's ultraviolet radiation, a short wavelength of light invisible to humans, that can cause sunburns. Sunburns are a factor that can lead to deadly health ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can ...

Safety Month – but how much do we really know about UV light and the effects it has on our bodies? UV rays are difficult to ...

UV-Vis spectroscopy analysis, absorption spectrum and absorbance units. UV-Vis spectroscopy information may be presented as a graph of absorbance, optical density or transmittance as a function of ...

The problem is that when seeking to prevent damage from UV light, we tend to remove the deep violet that is essential for eye health. This suggests that UV-A should be redefined to a 315-360 nm range.

A new study found that exposure to the UV light can kill cells and cause mutations that are typically seen in skin cancer. By. ... despite the devices using a different spectrum of UV light.
