Features

UV Fused Silica Substrates for UV Applications

UV Grade Fused Silica is synthetic amorphous silicon dioxide of extremely high purity providing maximum transmission from 195 to 2100 nm. This non-crystalline, colorless silica glass combines a very low thermal expansion coefficient with good optical qualities, and excellent transmittance in the ultraviolet region. Transmission and homogeneity exceed those of crystalline quartz without the problems of orientation and temperature instability inherent in the crystalline form. It will not fluoresce under UV light and is resistant to radiation. For high-energy applications, the extreme purity of fused silica eliminates microscopic defect sites that could lead to laser damage.

50/50 or 30/70 Beamsplitting

The UV beamsplitters are designed for a 45 degree angle of incidence, and are available in 50/50 and 30/70 reflectance/transmittance ratios in 250-450 nm spectral range. The choice of the beamsplitting ratios allows the scientist to use this beamsplitter in multiple applications that may require an even split or a 30/70 split. The beamsplitters are also provided with a broadband anti-reflection coating on the back surface to minimize any ghosting.
