1. JGS1 quartz lens ( 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 185mμ. Hence it is an ideal choice for applications in the wavelength range of 185-2500nm!
2. JGS2 quartz lens ( 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 quartz lens (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!
A variety of optical quartz lens glass can achieve the highest category
