monochromator

1 9.9
A device that chooses one color of light for experiments
  • noun
  • /ˌmɒnəˈkroʊˌmeɪtər/
  • Specialized
: monocromador
  • In reactor sources, the neutron wavelength is selected using a monochromator, which filters out all but a narrow range of wavelengths.

Examples

  • Monochromatic X-rays were generated using a double-crystal monochromator with Si(111) crystals.

    Academic text (2018)
  • Between the reactor and the spectrometer, he placed a sodium chloride crystal, and using Bragg reflection from this monochromator, he was able to select neutrons with a single energy from the continuous spectrum of neutrons in the beam.

    Academic text (1994)
  • The product family can operate in various scanning modes, including monochromator, chemometric, and digital transform.

    Academic text (2006)
  • (The three axes that give this spectrometer its name are those about which the sample and the initial and final monochromators rotate.)

    Academic text (1994)
  • The instrument uses a high-performance double monochromator to achieve ultralow stray light (0.00005% or less at 340 nm) while maintaining up to a 0.1-nm resolution.

    Academic text (2006)
  • The scientist used a monochromator to isolate a specific wavelength of light for the experiment.

  • In the laboratory, a monochromator helped separate light into its individual wavelengths for analysis.

  • The researchers installed a monochromator to accurately filter out unwanted wavelengths during the spectroscopy tests.

Morphology

monochromator = monochrome (semi-transparent) = monochrome + ator

Formally built from 'monochrome' + the agentive suffix '-ator', but the term is technical and uses combining forms, so the relation may not be fully obvious to general learners.

Etymology

Monochromator comes from mono- meaning 'one' and chrom- meaning 'color', the same parts in monochrome, which means 'one color'. So a monochromator is a device that picks out a single color of light from a mix of colors.
