Abstract
The diaphragm plates are individually adjustable in two-dimensional fashion. Semi-transparent diaphragm sections at the edges of the diaphragm plates limiting the radiation are adjustable perpendicular to the respective edge with a lever linkage such that the semi-transparent region becomes larger when the diaphragm is closed. A feedback control unit is present for operation. This feedback control unit has two operating pieces as an operating mechanism, which are displaceable by a user to positions similar to the diaphragm plates, and are electrically coupled to the feedback control unit to cause movement of the diaphragm plates to a position corresponding to the position of the operating plates.
