    Quartz glass

    Quartz glass are resistant against high temperature and pressure, and can be applied mainly in such fields as special light sources, optical instrument, optical electronics, military equipment, metallurgy, semi-conductor, and optical communications. Their experimental temperature is 1200 degrees and softening temperature 1730 degrees. Detailed parameters are given as follows:
      • 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.
      • 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.
      • 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.
