We produce custom CaF2 plano-convex lens, plano-concave CaF2 lenses; biconvex and bi-concave CaF2 lenses to 100% meet customer's demands. We can make lenses from 3 to 80mm diameter with almost any focal length.
Send RFQ to Sales Team.
Calcium Fluoride is used for lenses in transmision range 0.17-10µm. 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 lenses mostly used without an anti-reflection coating.
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!
Simple guide to CaF2 grade: Excimer, VUV, UV, IR.
* - Quotation depends on focal length, center thickness and quantity of lenses. We also welcome your custom requests!
