Plano-Concave (PCV) Lenses
Plano–Concave(PCV) Lenses are the most commonly used for light projection and beam expansion. Plano-Concave Lenses have one concave surface and other flat and provide negative focal length. PCV Lenses should be oriented with the plano or flat surface towards the desired focal plane.
Plano-Concave Lenses are ideal for use in a range of applications or industries. Coated with antireflective coatings lenses are used in various Optical Systems, Lasers and Assemblies. Catalogue items list consist of most common diameter and focal length Uncoated Lenses made from N-BK7. Any catalogue lens can be coated with dielectric or metallic coating.
