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.
