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.

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 present disclosure relates to a method for producing an optical element, for example a lens, for example a headlight lens, for example for vehicle headlights or motor vehicle headlights, wherein an optical component part having an (optically effective) convex surface made of a first transparent optical material is provided and/or produced; a mold having a concave cavity and optical material is provided and/or produced; liquid transparent second optical material is placed into the concave cavity of the mold; and the optical component part having the convexly curved surface is pressed into the concave cavity of the mold such that an optically effective coating is formed on the convexly curved surface.

Method for producing an optical element, for example a headlight lens for a motor vehicle headlight

The disclosure relates to a vehicle headlight (), for example a motor vehicle headlight, wherein the vehicle headlight comprises a light source assembly () and a primary optics (A), for example a press-molded primary optics, for example a one-piece primary optics (A), wherein the primary optics (A) comprises at least one light tunnel () and a wedge-shaped light conducting part () having at least one light exit surface (A), for example optically effective light exit surface (A), wherein the light tunnel () comprises at least one light entrance surface (), for example an optically effective light entrance surface (), into which light generated by means of the light source assembly () can be irradiated, wherein the light tunnel () transitions into the light conducting part () at a bend (), and wherein the vehicle headlight comprises a secondary optics (B) with an optically effective light exit surface () for imaging a light exit surface (A) of the primary optics (A) and/or of the light conducting part () or for imaging the bend ().
