CaF2 Window


Calcium fluoride window/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 nuclear physics experiments and detection of charged ions in  environmental radiation monitoring and radiological medical diagnosis.
