Do you know the difference between quartz glass?
According to the application of spectral band range, there are 3 kinds of domestic quartz glass.
| Grade | Quartz Glass | Application of wavelength range（μm） |
| JGS1 | Far UV Optical Quartz Glass | 0.185-2.5 |
| JGS2 | UV Optics Glass | 0.220-2.5 |
| JGS3 | Infrared Optical Quartz Glass | 0.260-3.5 |
| Parameter|Value | JGS1 | JGS2 | JGS3 |
