UV Fused Silica 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.
Hard Refractory Coatings for High Energy Lasers
These optics are precision polished, select grade fused silica coated with hard refractory multilayers for very high damage threshold. Three coatings are available covering the visible, NIR and IR regions with average reflectivity <0.5% per surface at 0º .
Fringe Patterns and Cavity Feedback Eliminated
A 30 arc min wedge between the polished faces eliminates fringe patterns and cavity feedback.
