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 sec- ond monochromator can be used to further enhance performance by allowing increased light through- put, reducing aberrations, and pro- viding low stray light levels. Double-beam spectrophotome- ters are operated using a beam sep- arated in space or a beam sepa- rated in time. WebPrinzip.
