China Jgs2 UV Optical Quartz Glass Windows

JGS2 uv optical quartz glass windows

Product description:
Haisheng Optical can produce optical quartz glass windows, it can able to bear high temperature and high pressure, mostly applied to special ray source, optical instrument, etc. It can experiment temperature up to 1200 degree, intenerate temperatures to 1730 degree.
1.JGS1( Extreme UV optical quartz glass)
It is a high-purity optical quartz glass made by oxyhydrogen flame melting. Its satisfactory UV light transmission performance surpass all the other glass types in particular in the shortwave UV zone and can achieve a 90% transmission rate at the wavelength of 185nm. Hence it is an ideal choice for applications in the wavelength range of 185-2500nm.
2.JGS2 (UV optical quartz glass)
It is an optical quartz glass made by oxyhydrogen flame melting and is suggested for applications in the wavelength range of 220-2500nm.
3. JGS3 (Infrared quartz glass)
It has a good performance of infrared light transmission with a transmittance of over 85%. It is recommended for applications in the wavelength range of 260-3500nm.
