Definition of collimate in English:

collimate

verb ˈkɒlɪmeɪtˈkɑləˌmeɪt

[with object]

1Make (rays of light or particles) accurately parallel.
使（光线，粒子线）平行
the caesium atoms are collimated into a narrow beam
Example sentencesExamples
- Once you can gather up and collimate the light coming from an LED, you can use binary optical elements - holographic diffusers - to take that round, highly collimated beam and put it out into designer patterns.
- 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 scattered light is collimated, and simultaneously detected by a fixed array of 18 transimpedance photodiodes, which span an angular region from 22.5 [degrees] to 147 [degrees].
- 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. 1.1 Accurately set the alignment of (an optical or other system)
  校准（光学系统或其他系统）
  manuals give detailed instructions for collimating the optics
  Example sentencesExamples
  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.
  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.
  The most common method for measuring retardance and fast-axis orientation involves placing two linear polarizers with horizontally aligned axes between a collimated optical source and a detector.
  The helicopter's weapon sighting system is the PKV collimating sight.
  In comparison, in a collimated system the peak wavelength varies across the FOV of the etalon filter according to = / 2n.

collimation

noun kɒlɪˈmeɪʃ(ə)nkɑləˈmeɪʃ(ə)n

Spiral CT scans (Somatom Plus Four; Siemens; Iselin, NJ) were performed using 3-mm collimation, 6 mm/s table speed, and 3-mm reconstruction.
Example sentencesExamples
- 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.
- Camera systems must have passed routine quality control checks with the collimation used and were photopeaked at 140 keV [+ or -] 10%. Whole-body images were acquired with a scan speed of 15 cm/min.
- 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.

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'.
