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.

Collimator, device for changing the diverging light or other radiation from a point source into a parallel beam. This collimation of the light is required to make specialized measurements in …

Nov 28, 2012 · Trust me — you don’t need one. As I noted in my write-up of collimation aids, in the hands of a beginner, a laser collimator is just as likely to make things worse instead of …

The meaning of COLLIMATOR is a device for producing a beam of parallel rays (as of light) or for forming an infinitely distant virtual image that can be viewed without parallax.

Mar 11, 2025 · The collimator is a beam direction device for changing the diverging light or other radiation from a point source into a parallel beam as shown in the figure below. An optical …

Jan 6, 2021 · A laser collimator is a device that is used to narrow a beam of light. It can be used to arrange the beam of light in a particular direction, or to reduce the spatial cross-section of a …

This can be done by simple visual methods such as looking down the optical assembly with no eyepiece to make sure the components are lined up, by using a Cheshire eyepiece, or with the …

Mar 21, 2023 · A collimator is an optical device used to narrow the beam of particles or waves. It's commonly used in medical imaging, astronomy, and physics research.
