Patent number: 12234174Abstract: The present disclosure provides an improved production method for optical elements. In this case, it is desirable to achieve high contour accuracy and/or surface quality for optical elements or lenses or headlight lens. In addition, it is desirable to reduce the costs of a production process for objective lenses and/or headlights, microprojectors or vehicle headlights.Type: GrantFiled: June 5, 2020Date of Patent: February 25, 2025Assignee: DOCTER OPTICS SEInventors: Alexander Kuppe, Ralf Polle, Thomas Walther, Peter Mühle, Christoph Dittmann, Stephan Jirak, Hagen Goldammer, Annegret Diatta, Sven Fröhlich

Patent number: 11884570Abstract: The disclosure concerns to a process for manufacturing an optical element from glass, wherein a blank of glass is tempered, for example in such a way that the blank is cooler in its interior than on its exterior, wherein the tempered blank between a first mold and a second mold, which are moved towards one another to form a closed cavity, is press-molded, for example on both sides, to form the optical element, wherein the first mold and/or the second mold comprises an escape cavity slide which is compressed by the formation of a closed cavity by means of the first mold and the second mold as a function of the volume of the blank, so that, during press-molding, an additional edge which is dependent on the volume of the blank is formed with the optical element.Type: GrantFiled: January 28, 2022Date of Patent: January 30, 2024Assignee: DOCTER OPTICS SEInventors: Alexander Kuppe, Annegret Diatta
