Bi-Concave Lens

Position >> Home page >> Products >> Bi-Concave Lens

Bi-concave lenses have two inward curved surfaces. These lenses have a negative focal length. Bi-Concave lenses are the best choice where object and image are at absolute conjugate ratios closer to 1:1 with converging input beam. The output rays appear to be diverging from a virtual image located on the object side of the lens. The distance from this virtual point to the lens is known as the focal length. Similar to the Plano-Concave lenses, the Bi-concave lenses have negative focal lengths, thereby causing collimated incident light to diverge. Bi-Concave lenses have equal radius of curvature on both side of the lens. They are used to diverge incoming light or increase the focal length of an existing optical system.
