For more information, please visit calcium fluoride optics.
Calcium fluoride (CaF2or fluorite) is grown by vacuum Stockbarger technique in diameters of up to about 250mm.
Crystal for infrared use is often grown using naturally mined fluorite to reduce costs. It will not have the best transmission in the UV and VUV and can have absorption bands at 300nm due to impurities.
For UV and VUV applications chemically prepared raw material is generally used. For Excimer applications, we use only the highest grade of specially selected material and crystal.
