Definition

A tool that creates a beam of parallel rays, often used in optics and radiation applications.

Example

The scientist adjusted the collimator to ensure the laser beam was perfectly straight.

Conversation

Have you heard about the new collimator they installed in the lab?

Yeah, I heard it helps with the precision of the experiments.

Exactly! It really makes a difference in getting accurate results.

I can't wait to see it in action during our next project!

Root Explanation

Collimator → It is formed from "col-" (from Latin "com-", meaning together) and "limare" (meaning to grind or polish). The word refers to a device that aligns light rays together, effectively polishing the beam for precision.

Memory Tip

Think of aligning things 'together' ('col-') and 'polishing' ('limare') the light rays to remember that a collimator is a device that makes light rays parallel.
