Fused Silica Window

The material of fused quartz has high temperature resistance, small coefficient of thermal expansion, good chemical stability and good performance in ultraviolet and infrared band. According to its optical properties, it can be divided into three categories:

JGS1 Far UV   Applied spectral wavelength  185- 2500nm

JGS2  UV    Applied spectral wavelength   220- 2500 nm

JGS3  IR     Applied spectral wavelength    260- 3500nm

As a first-class window material, it can be applied to the observation window of high temperature field, military and new technology field. Extremely high and stable optical properties under harsh working conditions.
