How about Optical Windows functions
Optical windows are applied to isolate different physical environments while allowing light to passing through.When selecting windows,it's important to consider materials,transmission, scattering,wave
front distortion,parallelismand resistance to certain environment.
so,Sapphire feature is more advantageous materials as optical windows.
what is Sapphire Optical Windows Feature
- 1. suitable for high power,high-pressure applications and vacuum or corrosive atmospheres.
- 2. Sapphire is a single crystal form of alumina.The material is extremely hard and resistant to attack by srong acid.
- 3. It has high compressive strength, a high melting point and excellent thermal conductivity.
- 4. Transmission range is from 150 nm to 5 µm.
- 5. low distortion,low scatter and excellent parallelism for laser and non-laser applications.
