METHOD FOR PRODUCING EMBOSSING TOOLS FOR MICROSTRUCTURE ELEMENTS USING ULTRA-SHORT LASER PULSES

摘要

The invention relates to a method for producing embossing tools (3, 3') consisting of a substrate (3, 3') in the surface of which embossed structures for microstructure elements, such as holograms, nanostructures or the like are introduced. According to the invention, the embossed structures for the microstructure elements are introduced in the surface of the substrate (3, 3') by means of ultra-short laser pulses from polarised electromagnetic waves or polarised electromagnetic radiation. A method for surface structuring is thus used in order to produce embossing tools (3, 3') for microstructure elements. The original structure can thus be transferred directly onto the surface of an embossing tool and film take-offs can be produced therefrom.
