The present disclosure provides a suitable method for producing a headlight lens for a vehicle headlight, for example for a motor-vehicle headlight, wherein the headlight lens comprises an integral body made of glass, wherein the integral body comprises at least one light tunnel and one light-passage section having at least one optically active light exit surface, wherein the light tunnel comprises at least one light entry surface and, with a bend, transitions into the light-passage section in order to image the bend as a bright-dark-boundary by means of light directed into the light entry surface.

Method for producing a headlight lens for a vehicle headlight

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.

Method for producing an optical element from glass

The invention relates to a method for producing an optical element from glass, wherein a portion of glass or a glass blank is blank-pressed, in particular on both sides, to form the optical element, wherein the optical element is then placed on a transport element and passes through a cooling path with the transport element, without the optical surface of the optical element being touched.

Method of producing an optical element from glass

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.

Process for manufacturing an optical element from glass

The present disclosure relates to a method for producing an optical element (), 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 (), in particular on both sides, and is then sprayed with a surface treatment agent.

Process for the production of an optical element from glass

A method for manufacturing an optical element out of glass comprises placing a blank made of glass on an annular contact face of a supporting body having a hollow cross section. The blank is heated on the supporting body in a cavity of a protective cap that is arranged in a furnace cavity, such that a temperature gradient is established in the blank in such a way that the blank is cooler inside than on an outside region. The blank is press molded to form the optical element.
