Thân thiện

The astronomer performs the collimation of the telescope before observing.

Definition

Noun: 1. The act of making parallel; the state of being parallel: In optics and surveying, "collimation" refers to the process of aligning optical components or sight lines so that they are perfectly parallel. 2. The accurate adjustment of the line of sight of an optical instrument: Specifically, it is the adjustment of a telescope, microscope, or other device to ensure its optical axis is correctly aligned for precise observation or measurement.

Usage

"Collimation" is a technical term used primarily in fields like astronomy, optics, physics, and surveying. It describes a critical setup or calibration procedure for instruments.

Examples

• Noun:
  • Proper collimation of the telescope's mirrors is essential for obtaining sharp images of planets.
  • The surveyor checked the collimation of the theodolite before beginning the measurements.
  • A misalignment in the laser's collimation caused the beam to diverge too quickly.

Advanced Usage

• "To be in/out of collimation": Describes the state of an optical system's alignment.
  • The microscope was out of collimation, resulting in a blurry and distorted view.

Variants and Related Words

• Collimate (verb): To make parallel; to adjust the line of sight of an optical instrument.
  • You must collimate the binoculars to match your eyes.
• Collimator (noun): A device used for producing a parallel beam of radiation or for aligning optical systems.
  • The X-ray machine uses a collimator to narrow the beam.

Synonyms

• Alignment: The arrangement of parts in correct relative position.
• Adjustment: A small alteration made to achieve a desired fit or result.

Antonyms

• Misalignment: The state of being incorrectly aligned.
• Divergence: The process or state of moving apart from a common point.
