Calcium fluoride is commonly used as a window material for both infrared and ultraviolet wavelengths, since it is transparent in these regions (about 0.15mm to 9mm) and exhibits extremely weak birefringence.
We provide artificially-crystallized calcium fluoride components available in IR grade and UV Grade. However the cost of UV grade is much expensive than IR grade.
