Optical glass windows are designed for using in optical systems to separate two environments while passing a particular spectral range between them.
It has high wavefront distortion, high transmission and high parallelism which ensure system’s imaging and high precision.
|Optical glass window Material - Sapphire|
Transparent Range: 180nm ~ 4500nm
Mohs Hardness: 9
Refractive Index: 1.755@1000nm
Sapphire has good mechanical strength, and it is also transparent from UV to IR spectrum.
So, it is always used as window material where scratch resistance is required.
For example for watches.
