Product Description

General Introduction: The Raytek high energy laser window is specially designed to eliminate losses in vacuum chamber applications and can be used as a vacuum window, convection grating or interferometer compensation plate.
UV fused silica for UV, laser and broadband applications
UV grade fused silica is a synthetic amorphous silica with high purity, which can provide maximum transmittance of 195 to 2100nm. The colorless amorphous quartz glass has very low thermal expansion coefficient, good optical properties and excellent transmittance in the ultraviolet region. The transmittance and uniformity are higher than that of quartz, and there is no inherent orientation and temperature instability of crystal morphology. It does not emit fluorescence under ultraviolet light and is radiation resistant. For high energy applications, the high purity of fused silica can eliminate the micro defects that may cause laser damage.
