Calcium Fluoride (CaF2) lenses

Alkor Technologies - manufacturer of custom Calcium Fluoride optical lenses for Ultraviolet and Infrared applications.

We produce custom:

  • plano-concave and plano-convex CaF2 lenses;
  • biconvex and bi-concave CaF2 lenses.
  • E-mail us for quote.

    We have own growth facility for CaF2 crystal growth. That is why we offer Calcium Fluoride (CaF2) lenses at very competitive price - up to 60% lower than major online optical catalogs!

    Calcium Fluoride is used for lenses in transmision range 0.15-9Ám. Degradation due to to moisture in the atmosphere is minimal and polished surfaces of the CaF2 lenses may be expected to withstand several years exposure to normal atmospheric conditions. Because of CaF2 low refractive index, Calcium Fluoride can be used without an anti-reflection coating.
