Plano Concave Lenses

Featured Product from BRD Optical Co., Ltd.


Optical Lenses are optical components designed to focus or diverge light. Plano-Concave (PCV) lenses have one flat and one inward curved surface. PCV lenses have a negative focal length and are used for image reduction or to spread light. As light passes through a lens, it is affected by the lensprofile or substrate.a Plano-Concave (PCV) or Double-Concave (DCV) lens causes the light traveling through the lens to diverge.
