Buying Monochromators

Monochromators are optical devices that function as tunable bandpass filters, allowing transmission of light within a narrow wavelength range, adjustable in center wavelength and bandwidth. They are integral components of spectrometers, spectrophotometers, and spectrographs, often based on the Czerny—Turner design or a variant thereof.
