Raman spectrometers lo holographicings ati awọn ipele pipin pipin pupọ lati ṣaṣeyọri iwọn giga ti didasilẹ laser. Ni igba atijọ, awọn photomultipliers ni awọn detectors ti o yan fun awọn iṣeto Raman pipin, eyiti o fa awọn akoko gbigba pipẹ. Sibẹsibẹ, awọn ohun elo igbalode fere gbogbo agbaye nlo awọn itọka notch tabi eti fun iṣiro laser ati awọn spectrographs boya axial (AT), Czerny<unk> Turner (CT) monochromator, tabi FT (Fourier spectroscopy), ati CCD Ìbéèrè: Kini idi ti o fi lo awọn photomultipliers gẹgẹbi abajade odi fun awọn detectors pipin Raman?
