Request InfoOptical Surfaces Ltd.KENLEY, UK, June 10, 2015 — Designed to collimate broadband light, off-axis parabolic mirrors from Optical Surfaces Ltd. are manufactured for demanding tolerances. The mirrors are commonly used as collimators in imaging systems, high-power laser focusing, astronomy, beam expansion, and bore sight alignment for missile guidance systems. Depending on the surface accuracy required, a natural limit to the off-axis angle can be achieved around 25 to 30° with surface microroughness of less than 1 nm. A range of coatings is available, from metallic to multilayer dielectrics, suiting all applications.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra July 2023 IssueMirror MountsWedged back paraboloid mounts from Optical Surfaces Ltd. provide a secure and stable platform for mirror diameters from 50 to 200 mm.
