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, ...
UVA rays have longer wavelengths, while UVB rays have shorter wavelengths. Both types can harm the skin, but they affect it differently; UVA rays penetrate deeper into the skin and can cause aging, while UVB rays are primarily responsible for sunburns and increase the risk of skin cancer. ...
You already know about SPF, UVB, sunburn and its relationship with skin cancer… but what about UVA protection? Newer research has really highlighted the…
High-Quality Construction: Our TO46 Metal Can GaN Based 355nm UVA/UVB/UVC Photodiode features a robust metal can design, ensuring durability and reliability in various lighting applications. Multi-Wavelength Sensitivity: This photodiode offers ...
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...
Effects on cells by UV radiation of shorter wavelengths, UVB and UVC, have been extensively investigated in terms of direct effects on DNA.1 UVA was initially perceived as innocuous to skin however, numerous reports recently have demonstrated cytotoxic effects after exposure of eukaryotic cells to ...

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 ...
