摘要
The present invention relates to an X-ray spectrometer with focusing by curved crystal and with multi-purpose X-ray emission chamber. This spectrometer is characterised in that the means controlling the displacement of the moving detection assembly 4, 5 comprise a rotary support 16, 20 rotating around the same axis as the curved crystal 3 and on which the moving detection assembly 4, 5 is mounted so as to slide radially, means are provided in order to move the support 16, 20 for the moving detection assembly 4, 5 in rotation, and the plate 15 supporting the curved crystal 3 and the plate 19 supporting the moving detection assembly 4, 5 are coupled together via a pair of arms 17, 18 which are hinged together, each of these arms 17, 18 having the same length R/2, R being the radius of the Rowland circle.
