Calcium
Fluoride is used for optical windows, lenses and prisms in
the 0.15¦Ìm - 9¦Ìm range.
This
material 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.
Calcium
fluoride is grown by vacuum Stockbarger technique. Material
for IR use is grown using naturally mined fluorite, in large
quantities at relatively low cost.
