- transitive verb To make parallel; line up.
- transitive verb To adjust the line of sight of (an optical device).
from The Century Dictionary.
- To bring into the same line, as the axes of two lenses or the telescope of an optical instrument; also, to make parallel, as the rays of light passing through a lens.
- To render the line passing through the optical center of the object-glass of a telescope and the middle wire of its reticule strictly perpendicular (or sometimes parallel) to the axis on which the telescope turns: usually by the aid of a collimator, or of star-observations in reversed positions of the instrument.

- transitive verb (Physics & Astron.) To render parallel to a certain line or direction; to bring into the same line, as the axes of telescopes, etc.; to render parallel, as rays of light.
- transitive verb an eyepiece with a diagonal reflector for illumination, used to determine the error of collimation in a transit instrument by observing the image of a cross wire reflected from mercury, and comparing its position in the field with that of the same wire seen directly.
- transitive verb (Optics) a lens used for producing parallel rays of light.

A slight vacuum is pulled behind an aluminized mylar plastic film to create a very large convex mirror to collimate the visual system in many aircraft simulators.
In fact, if the particles in the jet are fast enough, they can collimate themselves quite nicely due to relativistic effects.
In 2005 they used high-power ‘Luxeon’ LEDs, i.e. non-coherent sources, combined with a large Fresnel lens to collimate the non-directional light emitted, and managed two-way audio communications over a distance of 160 km (100 miles!) between mountaintops in Tasmania.
It was enough time to collimate a neutrino-beam and to fire it through the cases.
We collimate it so that we have a uniform beam illuminating the test piece.
Basically I seem to have designed a device which will collimate an extended light source.
Using a light pipe [such as fiber optic] won't help to collimate your beam, total internal reflection means that as the angle of incidence = = the angle of reflection, the light entering the pipe at random angles will exit just as randomly.
You can focus it to a point, but there's nothing you can do that will fully collimate the beam, i.e. it will always diverge.
You're going to want to collimate it, which is a way of aligning the optics.
There are two nouns morion kind of helmet, does not concern us here (it is probably from Spanish smoky quartz, has an interesting etymology: it is from a Latin word here about collimate, from an erroneous reading of Latin collineare; I wonder if there is a list somewhere of words with similar histories?
