Request InfoOptical Surfaces Ltd.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.
