In a goniometer having several axes around which a crystal specimen to be examined can be rotated, a radiation source, a detector for Bragg reflections and a detector for fluorescence radiation, with the detector making it possible to measure lattice geometry and chemical composition at the same time. The detector for the fluorescence radiation is secured in a holder, and is oriented with its surface parallel to the specimen and is pivotably secured together with the specimen to the specimen table. As such, reflexes can be simultaneously observed using the Bragg detector which is secured in a pivotable arm, and the fluorescence radiation using the fluorescence detector.
