Abstract: The disclosure relates to a method for manufacturing an optical element, where a blank of glass is heated and/or provided and, after heating and/or after being provided between a first mold (UF) and at least one second mold (OF), is press molded, for example on both sides, to form the optical element and is then sprayed with a surface treatment agent.

Abstract: 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.

Abstract: The disclosure relates to a method for producing an optical element (202), wherein a blank of transparent material is heated and/or provided and, after heating and/or after being provided between a first mold (UF) and at least one second mold (OF), is press molded, for example on both sides, to form the optical element (202) and is then exposed to a treatment atmosphere.

Abstract: The disclosure relates to a method for producing an optical element, for example an (optical) lens, for example a headlight lens, for example a vehicle headlight lens, from inorganic glass, wherein a blank of the inorganic glass is heated in a first heating step, for example in such a way that the blank is cooler on the inside than on its outer region, wherein, after heating, the blank is press-molded, for example on both sides, in a first pressing step between an upper mold and a lower mold to form an intermediate molded part, wherein the intermediate molded part is removed from the lower mold after the first pressing step, wherein a surface or the surface of the intermediate molded part formed by the lower mold and/or the surface of the intermediate molded part facing the lower mold is heated in a second heating step after the first pressing step, wherein the intermediate molded part is press-molded, for example on both sides, to the optical element or the (optical) lens, in a second pressing step after the

Abstract: The present disclosure relates to a method for producing an optical element (202), wherein a blank of transparent material is heated and/or provided and, after heating and/or after being provided between a first mold (UF) and at least one second mold (OF), is press molded to form the optical element (202), in particular on both sides, and is then sprayed with a surface treatment agent.

Abstract: 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.
