Abstract
In apparatus for radiation analysis, for example, X-ray spectrometers, the aperture angle of the analysing radiation beam is often desired to vary during the measuring process. The aperture angle of the radiation beam is determined, for example, by the length of the collimating elements in the collimator. In accordance with the invention, this is achieved by displacing or rotating the collimator through the radiation beam so that the collimating element length L exposed to the radiation beam can be varied in consequence. A collimator comprising rectangular plates (Soller collimator) can be rotated around a shaft perpendicular to the plates, or a collimator comprising X-ray fibres can be arranged with varying fibre lengths and displace them through the radiation beam transversely to the longitudinal direction of the fibres.
