Abstract:
An apparatus for carrying out X-ray fluorescence spectrometry comprising an X-ray generating tube and two paraboloidal X-ray reflecting mirrors, the generating tube having an X-ray source and an X-ray exit window through which X-ray radiation from said source is emitted, the first mirror being aligned on a first axis and positioned in close coupled arrangement adjacent to the exit window, the second mirror being aligned on said first axis and being positioned in spaced apart relationship to the first mirror, the first mirror being adapted to collect diverging X-ray radiation at its first end adjacent to the collecting window and to emit X-ray radiation in a substantially parallel beam at its second end, the second mirror being adapted to collect substantially parallel X-ray radiation at its first end closest to the first mirror and to emit X-ray radiation in a focused beam at its second end, the mirrors being arranged coaxially along their axis of symmetry, and the mirrors being paraboloids of revolution.
