Expanding light lens
WebThese lenses are widely used in increasing the focal length of the optical instruments. Biconcave Lens. Biconcave lens is also known as a double concave lens because both of its surfaces are curved inward, and the radius of curvature of both the surfaces is equal. These lenses are used in expanding light beams in projection systems. Convex ...
