Sapphire window and prism
Used as transparent barriers for sending and receiving light between two phases under varying conditions in temperature pressure chemical composition cleanliness and phase. Windows of synthetic optical sapphire crystal are highly abrasion-resistant with hardness approaching that of diamonds. The material allows transmission of light in the range from ultraviolet to near-infrared.
Uncoated Windows for 150 nm - 4.5 µm
