Product Description
These biconcave lenses are symmetrically concave negative lenses used when a very high negative power is required. They can be used in a multi-element system or alone to produce a diverging cone or a virtual image. Sharp edges, which are common in negative lenses, are removed by beveling to reduce the likelihood of chipping.
