Abstract

The reflector has a substrate having a surface structure and also has a highly reflective cover or coating layer. The surface structure of the substrate (2) has microscopic structure elements (3) having a size of between 10 and 1000 times the wavelength of the incident electromagnetic radiation. The cover or coating layer (4) has a uniform thickness over the entire surface. Independent claims also cover a method of manufacturing such a reflector.
