These lenses are thicker at the edge than in the Centre and flat on one side. The Plano–concave lenses are used to expand light beams or to increase focal lengths in optical systems.Plano–Concave lenses bend parallel input rays to diverge from one another on the output side of the lens and hence have a negative focal length. They are the best choice when object and image are at absolute conjugate ratios greater than 5:1 and less than 1:5 to reduce spherical aberration, coma and distortion.

Plano Concave (PCV) Lens The lens has negative focal length, diverges collimated light and hence used for beam expansion. It has minimum spherical aberration for negative-infinite near-infinite conjugates, when concave surface faces the infinite conjugate. A convergent beam incident on plane surface is transformed into collimated beam with least additional spherical aberration.
