Shown here is the spectrum of visible and non-visible light. The three types of UV radiation are classified according to their wavelength. Within the UVC range is a type called far-UVC ...

While tanning beds use a different spectrum of UV light (280-400nm) that studies have conclusively proven to be carcinogenic, the spectrum used in the nail dryers has not been well studied.

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 who ...

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 ...

UV radiation naturally comes from the sun, and from a few other artificial sources. The UV spectrum is itself made up of three parts, called UVA, UVB and UVC. Both UVA and UVB are associated with ...

A spectrum of ultraviolet light (340-395nm) is used to cure the chemicals used in gel manicures. T anning beds, known to cause skin cancer, use a different spectrum of UV light (280-400nm).

But the blue tapetum also lets up to 60% of ultraviolet light pass through to the eye’s color sensors. That means that reindeer see the winter world as a shade of purple, similar to how a person would ...

Description: The Aerapy All-Spectrum UV Monitoring System delivers real-time UV output reporting for HVAC disinfection and coil-cleaning applications. This patent-pending system automatically monitors ...

UV light exposure has been linked with a number of eye issues. “In short-term cases, overexposure to UV light can sunburn your eyes, caused by photokeratitis, which can be very painful and can ...
