Custom UV Fused Silica Windows AR Coated - AR-VIS, NIR-IR, UV & VIS-NIR
Looking for online stock? We sell that too
UQG supply UV Fused Silica windows and plates AR coated from a stock range or custom coated to your design. UV Fused Silica is very pure material and an uncoated surface has 92% average transmission from 180nm to 2 microns.
Adding AR coatings can reduce the reflection to less than 0.2% with transmission over 99%. The AR coatings range from the UV (ultraviolet), VIS (visible) and IR (infrared). Either broadband or single wavelengths coated for high laser damage thresholds or for camera windows for perfect imaging.
The UV Fused Silica windows and plates are made to custom specifications of flatness, surface finish and AR coatings. The stock AR coated range includes broadband AR coatings for wavelengths in the UV, VIS-NIR & NIR-IR regions. AR-VIS range, prices on request.
