Product Description

The Quartz glass plate/sheet can be customized as customer's request.

Borosilicate glass is a heat and shatter resistant material that is composed of silica and at least 5% boron oxide. Also commonly referred to as, this type of glass is mostly used for the manufacturing of products that handle strong acids and alkalis because of its resistancy to breakage and its high chemical resistance.

Good performance on Optical :
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.
