CaF2 Convex Lenses
Calcium Fluoride (CaF2) crystals, which are resistant to mechanical and thermal shocks, have transmittance in the UV, VIS and IR. Yutai Optics recommends using single crystal calcium fluoride to make lenses.

What is the refractive index of CaF2?
Calcium fluoride is the inorganic compound with the formula CaF2. It is commonly used as a window material for both infrared and ultraviolet wavelengths, since it is transparent in these regions. For a typical sample of CaF2 the refractive index and extinction coefficient at 632.8 nm are 1.43286 and 0.
