Calcium Fluoride is good choice for optical windows in the 0.13 μm - 9 μm range.
has found wide use in high power laser optics due to its low absorption. Polished surfaces are stable and will last several years under normal conditions. Due to its low refractive index, Calcium Fluoride can be used without anti-reflection coating.
