Fused Silica, UNCOATED

Fused silica has a lower coefficient of thermal expansion, which provides stability and resistance to thermal shock over a large temperature range. With increased hardness and resistance to scratching, fused silica windows are popular in applications set in stressful environments. They also provide superior transmission for the UV wavelengths, and is commonly used in laser applications or imaging systems set in the UV range.
