monochromator (plural monochromators)
(physics) An optical device, consisting of one or more slits, that selects a narrow band of wavelengths from a broader spectrum.
An alternate method for acquiring spectra is the "dispersive" or "scanning monochromator " method. Source: Internet
Obviously, a high-resolution monochromator is required for this technique, as will be discussed later. Source: Internet
Spectrometers for CS AAS When a continuum radiation source is used for AAS measurement it is indispensable to work with a high-resolution monochromator. Source: Internet
The advantage of this technique is that only a medium-resolution monochromator is necessary for measuring AAS; however, it has the disadvantage that usually a separate lamp is required for each element that has to be determined. Source: Internet
The second monochromator does not have an exit slit; hence the spectral environment at both sides of the analytical line becomes visible at high resolution. Source: Internet
These spectrometers use a compact double monochromator with a prism pre-monochromator and an echelle grating monochromator for high resolution. Source: Internet
