Abstract
The invention provides a block for partially limiting a radiation beam, allowing a first part of this beam to be limited corresponding to a first maximum half angle of opening. This rectilinearly movable block comprises a cylindrical active surface. Because of this active surface, said block defines new limits for the beam without modifying the starting orientation of this active surface in dependence on the positions which it may occupy through its rectilinear movement.
