摘要

Fluorescent X-ray analyzer comprises an X-ray source (1) for producing primary X-rays; a table for holding the sample (2); and a detector for detecting secondary X-rays produced by the sample. A collimator (4) only extracts secondary X-rays which are parallel to a line connecting a point on the central line of an optical X-ray stream produced from the source to a plane of the sample table and a central point of a detector zone of the detector. Preferred Features: The collimator comprises a parallel plate with thin metal leaves arranged in parallel at the same intervals.
