Crystal glass: good air permeability and low price.

3, the scope of application is different

Sapphire glass: It is used for night-vision infrared and far-infrared sights, night-vision cameras and other instruments and meters in satellite and space technology, as well as as as windows of high-power lasers, various optical prisms, optical windows, ultraviolet and infrared windows and lenses, and observation ports for low-temperature experiments, and has been fully applied in high-precision instruments and meters in navigation, aerospace and aviation.
