collimate

/ˈkɒlɪmeɪt

verb [with object]

1Make (rays of light or particles) accurately parallel: (as adjective collimated) a collimated electron beam...

The TPIAL emits a highly collimated beam of infrared light for precision aiming, as well as a separate infrared illumination beam with adjustable focus.
The excitation and transmitted light is collimated by a set of focusing lenses on either side of the sample chamber.
The first and second lenses operate jointly to concentrate and collimate the incident light beam.

1.1Accurately set the alignment of (an optical or other system): manuals give detailed instructions for collimating the optics...

I have done this many times while collimating a telescope's optical alignment and checking for the circular diffraction rings that occur at the same distance in and out of focus.
Our SBC cavity incorporates a single collimating lens located a focal length away from a 1 - D array of laser emitters operating at different wavelengths, with the grating positioned another focal length away on the other side of the lens.
The helicopter's weapon sighting system is the PKV collimating sight.

Derivatives

collimation

/kɒlɪˈmeɪʃ(ə)n

/ noun ...

Even with the collimation provided by a parabolic sending station, my gut feeling is that the physics (scattering, signal-to-noise, etc) is very much against it working.
Most HRCT protocols use thin collimation (at intervals or continuously) from apices to costophrenic angles in the supine position with image reconstruction using an edge-enhancement algorithm.
All CT images were taken on subjects in the supine position with an HRCT scanner (X-Vigor; Toshiba, Tokyo, Japan), with 2-mm collimation according to the previously reported protocol.

Origin

Mid 19th century: from Latin collimare, an erroneous reading (in some editions of Cicero) of collineare 'align or aim', from col- 'together with' + linea 'line'.
