ABSTRACT:
A method is described for the production of optical components, particularly of crystalline base material, with elevated stability and an optically active three-dimensional shape, which is defined by its surfaces, of high fit accuracy, by shaping the base material into a blank with a desired three-dimensional shape, and applying a covering layer to the surface of the thus-formed three-dimensional shape and the fit accuracy is obtained by abrasion of the covering layer.
