Abstract

A method for producing an optical element includes providing a first partial body which is transparent for the predetermined wavelength range and including on its upper side a structured section, applying a coating which is optically effective for the predetermined wavelength range onto the structured section in order to form the optically effective structure, and applying a cover layer which is transparent for the predetermined wavelength range onto the upper side of the first partial body by means of casting of thermoplastic material and/or duroplastic material.
