Patent attributes
An X-ray optical element (1, 1′, 1″) with a Soller slit comprising several lamellas for collimating an X-ray beam with respect to the direction of the axis (5, 15) of the Soller slit, and a further collimator for delimiting an X-ray (10), wherein the further collimator is rigidly connected to the Soller slit (2, 14) during operation, is characterized in that the X-ray beam (10) delimited by the further collimator intersects the axis (5, 15) of the Soller slit within the Soller slit, and the direction of the X-ray beam (10) subtends an angle α≧10° with respect to the axis (5, 15) of the Soller slit. An X-ray optical element (1, 1′, 1″) with a Soller slit (2, 14) and a further collimator is thereby realized, which permits automatic change between the Soller slit (2, 14) and the further collimator.
