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]

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]
