WebRaman Monochromators. A Raman monochromator can be a diffraction grating instrument, two or three diffraction grating instruments in series (double or triple monochromator), or a single element bandpass filter. A triple monochromator is an extremely flexible instrument, but it is very complex and it uses Raman photons very inefficiently. WebA monochromator is incorporated into fluorescence spectrophotometers and emission spectrometers to determine the wavelength of fluorescence lines or emission lines …
