Ultraviolet Glass
Ultraviolet glass (UV glass) is a kind of optical glass with high ultraviolet transmittance and low ultraviolet absorption. It is mainly used as window material of spectrometer, ultraviolet lens, optical filter, etc. It has short ultraviolet cut-off wavelength and high transmittance, and is commonly used in spectrometers, excimer laser optical systems, high energy laser systems, fiber optics and space. Property | Fused Silica Glass | UV-Black Glass | Soda-Lime Glass ** Transmittance Range 185-3500nm1 | 300-400nm | 200-300nm |
