Product Details

CaF2 Windows Product

Calcium fluoride (CaF2) window material has a light transmission range of ultraviolet light 0.13 ~ far infrared 10μm (there are five levels: IR infrared, VIS visible, UV ultraviolet, VUV vacuum ultraviolet, excimer level). It is excellent ultraviolet and infrared Window material.


Calcium fluoride (CaF2) crystals have a high laser damage threshold and are commonly used to fabricate optical components for excimer lasers. With strong shock and thermal shock resistance and good machinability. Calcium fluoride window is widely used in low energy experiments and detection of charged ions in environmental radiation monitoring and diagnosis.
