Bi convex lenses have positive focal length, so they are used for 1:1 imaging and in multi-element systems. Bi convex lens is a good choice when the object and image are at equal or near equal distance from the lens. Bi convex lens spherical aberration is larger than that of plano convex lens, so focal length may not gather at one point. We manufacture bi convex lenses with optical flint glasses, crown glasses, UV grade fused silica glass and infrared glasses. AR coating is applied to the surfaces of bi convex lenses for enhancing transmission.
