Double convex lens is thicker across its middle is an indicator that it will converge rays of light that travel parallel to its principal axis. A double convex lens is a converging lens. A double concave lens is also symmetrical across both its horizontal and vertical axis. Double-Concave Lenses are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double-Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths.
We provide Plano-convex lenses (DCV) with huge a range of coating or substrate options. Anti-reflection coatings range from the Ultraviolet (UV) to the Infrared (IR) with variety of focal length.
