Among all wavelengths of ultraviolet rays, only short wave ultraviolet UVC has the function of sterilization and disinfection. It belongs to a pure physical disinfection method. It has the characteristics of broad spectrum, high efficiency, fast and complete, no need to add chemical agents, no dru...
Ultraviolet radiation can be broken down into three bands: UVA, UVB, and UVC. Projection wafer stepper needs use single wavelength as light sources, such as: g-line, i-line, KrF and ArF. The broadband wavelengths of the UVA, UVB and UVC regions: UVA 400 nm - 315 nm, UVB 315 nm -...
UVA (wavelengths 320–400 nm) comprises more than 95% of the solar UV radiation that reaches Earth, making it far more abundant than UVB (280–320 nm) that accounts for the remainder. Most of UVB and all of UVC (wavelengths below 280 nm) are removed by the ozone layer and these short...
A non-dimer type of DNA damage does not appear to play a major role in either UVA or UVB mutagenesis. Therefore, the previously reported increasing mutagenicity per dimer with increasing wavelengths cannot be due to non-dimer DNA damage. Differences in the cellular response to UVA and UVB, ...

Of the three different wavelength groups of UV rays, UVA (longwave, 315–400 nm), UVB (middle-wave, 280–315 nm) and UVC (shortwave, 100–280 nm), the ozone layer absorbs almost all the UVC and some of the UVB. However, a big part of UVA reaches the earth’s surface passing ...
Ultraviolet radiation (UVR) from the sun is divided into UVC (200–290 nm), UVB (290–320 nm), and UVA (320–400 nm) [1]. Skin is the body organ that is most exposed to UVR. Human skin is constantly exposed to potentially harmful compounds and radiation because it serves as...
UV can be subcategorized into 3 different wavelengths which, from the lowest to the highest energy, are UVA (315–400 nm), UVB (280–315 nm), and UVC (100–280 nm). Even though the anterior structures of the eye such as the cornea and the lens are able to absorb and block UVB ...

and wrinkling2. UVB is particularly effective at damaging DNA and short bursts of high UVB doses cause sunburn, increasing the likelihood of developing skin cancer and cataract3. The shortwave UVC has the highest energy that can induce deadly damages to all lifeforms, including humans, plants, ...
