Double concave lenses are symmetrical with equal radius of curvature on both sides. The biconcave lenses are used in optical systems in combination with other lenses. These lenses also work as beamexpanders, optical character readers, viewers and projection systems. Lenses can be anti-reflection coated (please refer to the Coatings Section).
