Double Concave Lens

Bi-Concave (Double-Concave) lenses have equal radius of curvature on both sides of the lens and function similarly to plano-concave lenses by causing collimated incident light to diverge.

Double-Concave Lenses are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double-Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths.
