1. Method for producing a stamping tool with a structured stamping surface, comprising the steps of:
- oxidizing a surface or covering layer of the stamping tool for forming the stamping surface at least partially anodally and forming open hollow chambers that are at least essentially uniformly shaped and at least essentially evenly distributed over the surface or surface area of the stamping surface without the use of a model.

Abstract
A simple, cost-effective stamping or molding in the nanometer range is enabled using a stamping surface or molding face with a surface layer having hollow chambers that have been formed by anodic oxidation.

- 7. Method for structuring a surface of a work piece in a nanometer range by means of a stamping tool with a structured stamping surface, comprising at least one of pressing and rolling a stamping surface, formed of an anodally oxidized surface or covering layer with open hollow chambers which have diameters in a nanometer range that have been created model-free by anodic oxidation, onto the surface to be structured.

11. Method for at least partially structuring a surface of a cast work piece, comprising the steps of:
- casting the work piece using a casting mold with a structured molding face having an anodally oxidized surface or covering layer with open hollow chambers created model-free by anodic oxidation.

13. An anti-reflection surface, comprising:
a surface including at least one of projections of diameters in a nanometer range, and hollow chambers including diameters in a nanometer range, wherein the at least one of projections and hollow chambers on the anti-reflection surface are irregularly distributed, and wherein groups of the projections form larger projections of an order ranging from 0.1-50 micrometers, the larger projections including a surface having additional projections of 10-400 nm. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. An anti-reflection surface, comprising:
a surface including at least one of projections and hollow chambers distributed over the surface at a density of 109 to 1011/cm2, wherein the at least one of projections and hollow chambers have a substantially conical shape. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
