DETAILS
 

Fused silica window fused silica plate quartz plate quartz glass plate

It is designed for using in optical systems to separate two environments while passing a particular spectral range between them. 

It has high wavefront distortion, high transmission and high parallelism which ensure system’s imaging and high precision.

Application

Fused silica glass has mainly three types of fused silica, JGS1, JGS2, JGS3.

JGS1 is mainly used for optics operating in the UV and the visible wavelength range. It is free of bubbles and inclusions.

JGS2 is mainly used as mirror substrate, as it has tiny bubbles inside.

JGS3 is transparent in the ultraviolet, visible and infrared spectral regions, but it has many bubbles inside.
