Plano Concave/Double concave Lens

A plano-concave lens is an optical lens with one flat surface and one inward-curved concave surface, designed to diverge light and has a negative focal length.   Plano-concave lens features a flat(plano) surface on one side and a concave surface on the other. this design gives it a negative focal length, causing parallel light rays to diverge as if they originated from a virtual focal point on the concave side, the lens have negative spherical aberration, used to correct or balance aberrations in optical systmes.   Plano concave lenses (PCV) are ideal for beam expansion, light projection and focal length adjustment in optical systmes, designed with one single concave surface and one negative focal length, these lenses effectively diverge light for laser optics, medical imaging microscopy and fiber optics applications   Materials and Coatings   K9 and CDGM optics glass for visible and near IR application   UV fused silica for UV application   Sapphire, Znse, ZnS,CaF2,BaF2, Silicon for i…
