Bi concave lenses comprise of two inward equally curved surfaces. They are ideal for beam expansion, light projection and expanding the focal length of an optical system. Bi concave lenses have a negative focal length, so the lenses are used for image reduction or to spread the light. The bi concave lenses are offered with different diameters and focal lengths. We are able to do anti-reflection coating for the lenses, including single layer AR coating, multi-layer broad band AR coating for visible wavelengths, UV wavelength and infrared wavelength. The AR coating helps to improve the transmission of the lenses greatly. We offer customized bi concave lens, so please send us drawing or specification.
