Fused Silica Windows

产品说明

Fused Silica Window is made from the material of fused silica. Fused Silica is a superior optical material possesses excellent optical, chemical and physical properties which is formed by chemical combination of silicon and oxygen.

Advantages of fused silica windows include: good UV and IR transmission, stability and resistance to thermal shock over large temperature excursions, low thermal expansion, wider thermal operating range and high laser damage threshold.
