The optical elements of different cemented lens composed of two kinds of refractive index, which are glued together to provide a positive focal length of the imaging lens. A cemented lens of the optical axis chromatic aberration and the spherical aberration is corrected, making it suitable for broadband optical cemented lens. Available focal length and a wide range of diameters. Please ask size and focus are needed, because we can offer a variety of optical cemented lens. Our main products are prism including a triangular prism, pentagonal prism, roof prism. Such as plano-convex lenses, plano-concave, biconvex, biconcave. All of these products have different sizes, we can customize according to drawings and samples cemented lens, a wide range of focal lengths and diameters are available. Please ask size and focus are needed, because we can offer a variety of optical lens glued
