Bi-Concave Lenses

Custom BiConcave LensThese lenses are similar to plano-concave lenses and are best used with absolute conjugate ratios between 1/5 and 5. Bi-concave glass lenses are manufactured with both surfaces concave. These lenses have negative focal lengths.
These lenses diverge collimated incident light and form virtual images, which are seen through the lens. They are used in f.e. laser beam expanders, optical character readers, viewers, and projection systems.
