Abstract
A collimator for a ray diagnosing device for taking pictures produced by gamma rays or similar penetrating rays consists of a honeycomblike constructed body with many holes, the walls of which absorb the rays. The invention is particularly characterized in that the walls of the collimator are made of strips which extend parallel to each other in their longitudinal directions and are so folded transversely to their longitudinal extension that when two strips are placed next to each other one side of a strip makes a series of holes with the adjacent side of the following strip, the holes having a symmetry axis which coincides with the line separating the two strips.
