1. The plural of collimation; the process or result of aligning optical or particle beams so that they are parallel or directed toward a specific point.
Usage: technical; used in optics, astronomy, and physics
2. In surveying and astronomy, the adjustment of an instrument's optical axis to ensure accurate measurements.
Usage: technical; surveying and astronomy contexts

Examples

• The telescope required several collimations before the observations could begin.
• Proper collimations of the laser beam ensured precise cutting in the manufacturing process.
• The astronomer performed collimations on the instrument to eliminate optical errors.
• Multiple collimations were necessary to align the particle accelerator's components.
• The surveyor checked the collimations of the theodolite to guarantee accurate measurements.
