摘要：The invention is an improved energy dispersive x-ray spectrometer comprising x-ray source (10), sample (12), optics (20) and detector (16). The improvement compris the u of optics using the principle of total external reflection for delivering an incread flux of x-rays onto the detector. The flux concentrating optics are generally shaped as tubes having a figure of revolution as a longitudinal cross ction such as a cone, parabola, hyperbola, ellipsoid and others. The optics may also be ud as low energy pass filters by incorporating a stop (22) at or near the aperture of the optic. The reflecting surface of the flux concentrator optic may be lected from the group of metals and their alloys, the choice made to optimize the optic's performance.
