Request InfoOptical Surfaces Ltd.ENLEY, England, April 18, 2011 — Optical Surfaces Ltd. can typically produce off-axis parabolic mirrors up to 600 mm in diameter with surface accuracies to λ/20 peak to valley, depending upon off-axis angles. With proprietary polishing techniques, the company can, depending upon the surface accuracy required, achieve the natural limit to the off-axis angle of around 25° to 30° and surface micro-roughness on aspherics of ~1 nm rms. Coatings are available for standard and custom components from metallic with or without protective overcoat, to multilayer dielectrics and ultrahard coatings. ...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.
