An x-ray fluorescence analysis device, including an x-ray source for irradiating a sample with x-ray radiation, an x-ray detector for measuring x-ray fluorescence radiation emitted by the sample, and a camera for producing an optical control image of the irradiated measurement point of a sample by means of an optical mirror arranged at an angle in the beam path of the x-ray source, which optical mirror includes a carrier having a mirror layer provided on the carrier. In order to create an x-ray florescence device by means of which realistic control recordings of the sample to be analyzed, in particular of the sampled surface point, the optical mirror has a passage window for the x-ray radiation, which is formed by an opening in the carrier and a foil forming the mirror layer and covering the opening on an outer surface of the carrier.
