WebPrinzip. UV/VIS-Spektroskopie beruht auf Messung der Extinktion von sichtbaren und ultravioletten Licht durch eine Probe. Die spektrale, d. h. wellenlängenabhängige, Information kann entweder durch Selektion und Scannen der Wellenlänge des einfallenden Lichts vor der Probe (siehe unten, Zweistrahl-Spektrometer) oder durch Trennen der Wellenlängen des … 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.
