Abstract

A collimator is disclosed for a radiation detector including at least three spacing elements arranged on a radiation exit face of the collimator. In at least one embodiment, they are embodied so as to mount the collimator in a stable manner with respect to a radiation converter of the radiation detector. The at least three spacing elements enable a very precise and stable alignment of the collimator in respect of the radiation converter despite manufacturing-related curves or unevennesses in the radiation exit face and/or the mounting surface on the part of the radiation converter. At least one embodiment of the invention also relates to a manufacturing method for such a collimator, as well as a method for manufacturing a radiation detector.
