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-BCC000
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]

from Rolyn Optics Company

A Bi-Concave Lens is a divergent or negative lens, thicker at the edge than in the center. All ROLYN Bi- Concave Lenses are symmetrical having equal radii on both sides. These lenses form a virtual image and are frequently used to extend the effective focal length of a converging lens when they are... [See More]
