Pronunciation

/ˈkɒlɪˌmeɪtə/

Definitions

1. An optical instrument used to make light rays parallel.
2. A device used in physics and engineering to align or direct rays of light or particles to a specific direction.
3. In astronomy and optics, a tool used to improve the precision of telescopes or other instruments by adjusting the alignment of light sources.

Usage Examples

• The engineer calibrated the collimator to ensure the laser beam was parallel.
• Before taking measurements, the scientist used a collimator to focus the rays of light.

Etymology

The word "collimator" comes from the Latin word "collimare," which means "to align or aim at," formed from "com-" (together) and "limare" (to smooth or make even). The term began to be used in the context of optics and scientific instruments in the 19th century.

Synonyms

• Aligner
• Focusing device
• Optical instrument
• Beam director

Antonyms

• Disperser
• Scatterer
• Deviator
• Diverger

Historical Usage

The term "collimator" was first introduced in the early 19th century, specifically in the field of optics. The invention of the collimator was essential in the development of telescopes, microscopes, and other instruments where accurate alignment of light or beams was necessary. Over time, collimators became integral tools in fields like physics and engineering, helping improve precision in measurements and experiments.

Cultural Nuances

The concept of "collimating" has transcended the technical realm into broader cultural contexts. In scientific disciplines, precision and alignment are crucial values, and these same qualities are often emphasized in various cultural practices, such as aligning one’s life goals or focusing on specific objectives. The use of collimators reflects a cultural appreciation for accuracy and clarity in both professional and personal domains.

More Information

Collimators are vital components in the fields of optics, astronomy, and engineering. By ensuring that light rays or particle beams are aligned in parallel, collimators enhance the effectiveness of instruments like telescopes, microscopes, and lasers. Their role is crucial for obtaining accurate data and images, making them indispensable in scientific research and technical applications. Understanding the use of collimators is fundamental for professionals working in precision fields, from physics to medical imaging.
