<p>An X-ray analysis apparatus comprises an adjustable entrance slit (11) which consists of two laminations (13, 15) which are rotatable about axes extending parallel to a theta -axis (6). By choosing the radius of the laminations and their position in the X-ray beam, a substantially more accurate adjustment can be achieved notably for small theta -values. Moreover, asymmetry in the beam path can be simply compensated for and improved shielding against scattered radiation is achieved. <IMAGE></p> |
