Abstract: An optical assembly for the illumination and hyperspectral evaluation of an object, having a light source or an optical element at which a light source radiates, wherein the light source or the optical element is designed to divide pairs of unambiguously assignable photons into a first light beam and a second light beam so that the first light beam hits a first detector system and the second light beam is directed at an object and light radiation coming from the object is directed at an optical element which spectrally decomposes light radiation and, from the optical element spectrally decomposing said light radiation, is directed at a second detector system. The first light beam can also be directed at a spectrally decomposing optical element and, from there, at a first detector system, and the light radiation coming from the object can be directed directly at the second detector system.

Abstract: The invention relates to the optical assembly for the illumination and hyperspectral evaluation of an object, having a light source or an optical element (1) at which a light source radiates, wherein the light source or the optical element is designed to divide pairs of unambiguously assignable photons into a first light beam (2) and a second light beam (5) in such a way that the first light beam hits a first detector system (4) and the second light beam is directed at an object (7) and light radiation coming from the object is directed at an optical element (8) which spectrally decomposes said light radiation and, from the optical element spectrally decomposing said light radiation is directed at a second detector system (9). The first light beam can also be directed at a spectrally decomposing optical element and from there, at a first detector system, and the light radiation coming from the object can be directed directly at the second detector system.
