Description

Details

Plano-concave lens is the most common item used for light projection and beam expansion. Coated with antireflective coatings, lenses are used in various optical systems, lasers and assemblies. Catalog items list consist of most common diameter and focal length uncoated lenses made from BK7; UVFS; CaF2 and ZnSe. Any catalog lens can be coated with dielectric or metallic coating (please refer to the coatings section).

Features

Diverges incident light
Reduce spherical aberation
