ABSTRACT:
A method of making microstructure bodies of plastic material. A microstructured plate-like base body which is made by any known molding procedure and which has a first side serving as a first reference plane and a second side which has plastic microstructures projecting therefrom is covered at its second side with a material layer that engages the microstructures, whereupon the material layer is machined to provide a second reference surface parallel to the first reference surface and the base body is then machined parallel to the second reference surface to expose the microstructures projecting therefrom and the material layer is finally removed selectively with respect to the plastic material to release the microstructured bodies.
