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.

A method for the production of optical components, particularly of crystalline base material, with elevated stability and an optically active three-dimensional shape of high fit accuracy defined by its surfaces due to shaping the base material into a blank with the desired three-dimensional shape, comprising applying a covering layer onto the surface of the thus-formed three-dimensional shape and the fit accuracy is obtained by abrading the covering layer, wherein said base material comprises a member selected from the group consisting of CaF2, BaF2, LiF, NaF, KF and combinations thereof.
