Image
 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 used as a pair.
