WebInstrument Designs for Molecular UV/Vis Absorption Single-Beam Spectrophotometer An instrument that uses a monochromator for wavelength selection is called a spectrophotometer. The simplest spectrophotometer is a single-beam instrument … 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.
