The disclosure relates to a method for producing an optical element () having at least one optically effective surface, wherein, by means of a first injection mold of an injection-molding machine (') liquid transparent plastic (, P, P) is injection-molded to form a preform and/or a pre-molded part () having at least one preform (), the preform or the pre-molded part () subsequently being cooled outside the first injection mold and/or outside the injection-molding machine (′), and the preform () to form the optical element subsequently being injection-molded and/or over-molded in a second injection mold by applying at least one layer of plastic, which forms the optically effective surface ().

Method for producing an optical element from plastic

The disclosure relates to a method for producing an optical element having at least one optically effective surface. The optically effective surface comprises a contour and a surface structure superimposed on the contour. Transparent liquid plastic is injection-molded by means of a (smooth) injection mold of an injection molding machine () in dependence on a group of injection molding parameters to form an injection molded component () having the contour of the optically effective surface but without the surface structure superimposed on the contour, wherein at least one parameter of the group of injection molding parameters is set and/or corrected in dependence on properties of the injection molded component (), and wherein the optical element is produced using the group of injection molding parameters.
