UQG Optics

UV Fused Silica Windows - Plates - Substrates
Fused silica windows are highly transparent and makes it an excellent choice for use in the (UV) ultraviolet 170nm to 2000nm. The material is fluorescent free and can withstand temperatures up to 1000°c

UQG custom UV fused silica window ranges include all plano flat fused silica components manufactured to custom made sizes, specifications and in a range of materials,

Manufactured from a large inventory of stocked raw materials and from extensive production overruns we can supply small to production quantities.
