Product Description

Plano Concave Lens:
These lenses are thicker at the edge than in the centre and flat on one side.

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. Because the spherical aberration of the Plano-Concave lenses is negative,they can be used to balance aberrations created by other lenses.

Concave lenses have several uses, including in eyeglasses and contacts, flashlights, peepholes, binoculars,telescopes, and in photography.
