JGS1 Spectrum curve.
The JGS1 quartz glass is a kind of far ultraviolet quartz glass material.It has best transmission of ultraviolet rays in quartz glass.Extremely high purity of SiO2 which is over 99.9999%.It's also named synthetic quartz,specially used for water purification,ozone generation,chemical processing etc.
This JGS1 quartz glass is a high purity synthetic amorphous silicon dioxide manufactured by flame hydrolysis, which has properties such as high purity, exceptional transmittance, well homogeneity, very low birefringence, no straie, no granular structures, no bubbles, no inclusions, no fluorescence, outstanding laser injury resistant, and also it combines other quartz's thermal, electrical, mechanical and chemical properties. It is very applicable to use in the near-infrared, visible and deep UV spectral range of optical and various high-tech areas.
JGS2 quartz plates & quartz discs
The most popular high purity (SiO2 over 99.99%) quartz glass window is made of material JGS2 in China,this material is made by flame fusing.It is widely used in semiconductor and solar industry,for making optical quartz glass parts such as slides,quartz lens,prism,observation window etc.Another two kind of quartz material is JGS1-far ultraviolet opticla quartz glass and JGS3-infrared optical quartz glass.
Material: JGS2, equivalent to GE214,made by flame fused,small or none tiny gas bubbles,SiO2 over 99.99%,OH content around 120ppm,most common material for optical application,it's chemcial composition as below(only for reference)
Quartz Basic Characteristics:
A. The average thermal expansion coefficient at 0 ~ 1000°C is 5.4 x 10-7/°C
B. Recrystallization temperature: Initial temperature is about 1000°C, while the dirty surface will cool down the recrystallizaion temperature and speed up the recrystallization process
C. Normal operating temperature:
Continuous usage: About 1050°C
Non-continuous usage: About 1250°C
D. Characteristic temperature:
Strain temperature: About 1075°C
Anneal temperature: About 1180°C
Hot processing temperature: About 1700~2100°C
JGS3 quartz plates & quartz discs
