Ross Optical Bi-Concave Lenses
Compare
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 to diverge incoming light or ...
