Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Rashin watsawa na Raman kai tsaye yana da rauni sosai, kuma a sakamakon haka babban wahalar Raman spectroscopy shine raba raunin haske mara ƙarfi daga hasken laser mai ƙarfi na Rayleigh. A tarihi, Raman spectrometers sun yi amfani da grating na holographic da matakai masu yawa na watsawa don cimma babban matakin kin amincewa da laser. A baya, photomultipliers sun kasance masu ganowa na zabi don watsa shirye-shiryen Raman, wanda ya haifar da dogon lokacin saye. Koyaya, kayan aikin zamani kusan gabaɗaya suna amfani da filtata ko filtata na gefen don ƙin yarda da laser da masu ɗaukar hoto ko dai axial transmissive (AT), Czerny<unk>Turner (CT) monochromator, ko FT (Fourier canza spectroscopy bisa), da masu gano CCD.  Tambaya: Mene ne mummunan sakamakon da aka yi amfani da shi don amfani da photomultipliers a matsayin masu bincike a cikin Raman saiti?
