Product Introductions:
Quartz glass can transmit far ultraviolet, transmit visible light and near infrared optical curve.
It is characterized by small heat expansion factor, stable chemical capacity. Bubble, stripe and double refraction are better than common optical glass.
Quarts glass is necessary optical glass to stable optical factor in bad condition. Mainly apply in military, laser, metallurgical, optical instrument and stage light etc. high temperature window.
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.
