Knight Optical's stock range of UV fused silica windows are made from Corning 7980 grade 2G or equivilent of Spectrosil B. UV grade fused silica windows have excellent UV transmission working efficiently at 175nm. Making them ideal for spectroscopic instruments in the UV.

These UV fused silica windows also have excellent chemical stability, can be used up to 1050°C and are virtually free from fluorescence. Our stock windows are flat and parallel with good quality surfaces making them ideal for demanding scientific instrument applications. Stock windows can be edged down or re-shaped for custom fused silica parts at short notice and we can offer them both uncoated or with AR coating for 248nm-400nm.
