Plano-Concave Lenses are ideal for beam expansion, light projection, or for expanding an optical system's focal length. Plano-Concave Lenses, which have one concave surface, are Optical Lenses with negative focal lengths. PCV Lenses should be oriented with the plano, or flat, surface towards the desired focal plane. PCV Lenses are ideal for use in a range of applications or industries..
