"In X-ray optics, gamma ray optics, and neutron optics, a collimator is a device that filters a stream of rays so that only those traveling parallel to a specified direction are allowed through. Collimators are used for X-ray, gamma-ray, and neutron imaging because it is difficult to focus these types of radiation into an image using lenses, as is routine with electromagnetic radiation at optical or ne… " - Collimated beam apparatus

WebA collimator is an equipment that narrow-down a beam of waves/particles, by a collimation technique. Narrow can mean to be aligned in a particular direction (i.e., create collimated light or parallel beams ), or to create the spatial cross-section of this ray or beam to become narrower (beam limiting device).
