| titleOfInvention | Method for producing an optical element from plastic |
| abstract | The disclosure relates to a method for producing an optical element ( 42, 43 ) having at least one optically effective surface, wherein, by means of a first injection mold of an injection-molding machine ( 500, 500 ′) liquid transparent plastic ( 54 , P 4014 , P 4017 ) is injection-molded to form a preform and/or a pre-molded part ( 20 ) having at least one preform ( 22, 23 ), the preform or the pre-molded part ( 20 ) subsequently being cooled outside the first injection mold and/or outside the injection-molding machine ( 500, 500 ′), and the preform ( 22, 23 ) 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 ( 42, 43 ). |
