Plano Concave Lenses in China

A plano-concave lens is a lens that has a flat surface on one side and a concave surface on the other side. The focal length of a plane-concave lens is negative, allowing the beam to diverge. Therefore, it can be used in optical system for beam expansion, light projection or to increase focal length

We are engaged in offering Plano Concave Lenses, which consists of the following specification:- Material: flint glasses, UV-fused silica, Infrared fused silica, CaF2, Ge, ZnSe, Si, etc. Focal length:+/-5mm-- +/-1000mm+/-1% (test by TIROPTICS OPTOMATIC2000 made in German) Length: 2mm-300mm +/-0.1mm
