Double-Concave Lenses
from Artifex Engineering

Double-Concave (DCV) lenses have two inward curved surfaces. DCV lenses have a negative focal length and are used for image reduction or to spread light. [See More]

Bi-Concave Lens -- L-BCC025
from Ross Optical Industries

Bi-concave lenses have two inward curved surfaces. These lenses have a negative focal length. Our catalog bi-concave lenses have an identical curvature on both sides of the lens and are therefore symmetric. At unit conjugation, coma and distortion are cancelled out due to the symmetry. They are used... [See More]
