Abstract

An apparatus for illuminating the surface of a material, comprising an illuminating device for illuminating the surface of the material with a calibrating light, a recording device for recording a measuring light, emitted by the surface of the material in response to the calibrating light, and a processor device for recording the spectral characteristic of the measuring light that characterizes a diffuse spectral reflectance of the surface of the material, wherein the illuminating device is configured to generate an illuminating light for illuminating the surface of the material that has a spectral characteristic that corresponds to the spectral characteristic of the measuring light.
