Alkor Bi-Convex Lens
Description
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. 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. Fused Silica is used for lenses in the transmission range 0.18-3.5µm. Fused Silica refractive index varies from 1.55 to 1.40 through the transmission range. Fused Silica lenses resistant to scratching and thermal shock, and suitable for large number of laser and optical applications. AR Coatings can be applied on Fused Silica lenses to improve transmission on your laser line or broadband spectrum range.
