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 spectroscopy and in geometric and physical optics.

Collimator sights, also known as occluded eye gunsights (OEGs), are designed for use with both eyes open. The user aligns one eye with the sight while the other eye remains open and focused on the target.

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 beam to make it smaller.

Jan 17, 2025 · A collimator transforms divergent beams of light or particles into parallel rays through a series of optical elements. This precise alignment creates focused beams for applications in medical imaging, astronomy, and scientific research.

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.

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.

Jun 10, 2013 · A collimator may be described as a device that focuses or narrows a light beam or a stream of particles to be aligned in a different direction or reduce its cross section.

A collimator is an optical device used to produce a parallel beam of light or other radiation. It is an essential component in various visible-light detectors and instruments, ensuring the efficient collection and analysis of light signals.
