Abstract

The invention relates to a method for producing a (sub) microstructure on a curved surface of an optical component. The method comprises the following method steps: providing an elastic carrier foil with a separable reinforcing foil; a model object provided with a (sub) microstructure; applying a forming film on the front side of the carrier foil; forming a (sub) microstructure of the model objectin a case where the structured forming film is formed; clamping the carrier foil coated with the structured shaped film together with the reinforcing foil in a holding frame; applying a transfer filmonto the structured forming film; separating the reinforced foil from the rear side of the carrier foil; pressing the optical workpiece to be structured onto the structured forming film coated with the transfer film in the case of forming the structured transfer film; aging-strengthening the structured transfer film adhered to the workpiece in a case where the optical member structured with the (sub) microstructure is formed. The structured optical member is removed from the molding film.

Description

technical field [0001] The invention relates to a method for producing (sub)microstructures on curved surfaces of optical components. Furthermore, an embodiment variant of an optical component produced according to the method is also specified within the scope of the invention. [0002] Within the scope of the present invention, the term "microstructure" refers to those structures whose characteristic dimensions are in the micrometer scale of one micrometer (μm) to a few micrometers (μm). "Submicrostructure" refers hereinafter to the relevant structures having characteristic dimensions of less than one micrometer (μm) and thus in the submicrometer scale. The term "submicrostructure" therefore also encompasses structures with characteristic dimensions or structural sizes of a few nanometers (nm). Hereinafter, the term "nanostructure" means that the relevant structure has a characteristic length dimension in the nanoscale, essentially in the range of a few nanometers to a tent...
