Abstract
A device for filtering a ray bundle of electromagnetic radiation, particularly an X-ray bundle has different filter stages, produced by multiple filters that can be adjusted into the ray bundle, a drive for moving the filters, and separate arms for moving each of the filters. The respective first ends of the arms engage at the appertaining filter and the respective other ends thereof are chargeable with a force generated by the drive. Dependent on the motion of the drive, each of the filters can either be set into the beam path by charging the appertaining arm with an actuating force or can be retrieved from the ray bundle by charging the arm with a restoring force. A dog driven by the drive is able to be brought into contact with two detents respectively present at each of the arms. An IN detent is provided for charging the arm with the actuating force and an OUT detent is provided for charging the arm with the restoring force. For mechanical encoding of the arms, each arm has a position of the IN detent and a position of the OUT detent that differ from arm-to-arm.
