X-ray optical system

摘要

An X-ray optical diaphragm (3; 4) which is provided with at least one passage opening (3a; 4a) for rays is constructed in such a manner that the edge zone (9; 10) of the X-ray optical diaphragm (3; 4) which faces the passage opening (3a; 4a) is angulated at least partly relative to the direction of propagation (7) of the rays.
