UV Fused Silica Substrates for UV, Laserline & Broadband 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.

Mount in Standard Lens Mounts

These round plano-convex cylindrical lenses are designed to mount into standard optical lens mounts.  The round optic shape provides many more mounting options compared to rectangular cylindrical lenses that require special cylindrical lens mounts for mounting.
