1. Plural of monochromator; optical devices or instruments that select or produce light of a single wavelength or narrow range of wavelengths.
Usage: technical; physics/optics

Examples

• The laboratory uses several monochromators to isolate specific wavelengths of light for spectroscopy experiments.
• Modern monochromators employ diffraction gratings to separate light into its component wavelengths.
• The researchers calibrated the monochromators before beginning their UV absorption measurements.
• Prism-based monochromators are commonly used in analytical chemistry to filter light.
• The instrument contains multiple monochromators to handle different regions of the electromagnetic spectrum.
