Fused Silica Quartz glass window is smelted by high purity(>99.99%) of Quartz(SiO2) material, the Fused quartz glass can be used as precision optical elements in the industrial photoelectric field. Quartz glass window can work for a long time at a high temperature of 1200 °C, and is resistant to abrasion and acid and alkali (except HF).

The JGS1 of Fused Silica has high transmittance(>90%) in 180~2500nm wave band, it is used as VUV window. 
The JGS2 of Fused Silica has high transmittance(>90%) in 220~2500nm wave band, it is used as UV window. 
The JGS3 of Fused Silica has high transmittance(>90%) in 700~3500nm wave band, it is used as IR window. 

We can customize different size and thickness of Fused Silica optical window upon requirements, such as Fused Silica round wafer, Square substrate and Cylinder, or Punch holes and other shapes.
