Abstract
The performances of different polarizers and analyzers used in the Raman spectrometer are different, they effect the depolarization of Raman spectrum. Three polarizers and three analyzers are characterized using the spectrum of Cary5000 in the wavelength range of 505-610nm. The polarizer are chosen with the best performance and the worst performance among three polarizers. These two polarizers in turn combine with three analyzers to measure the Raman spectrum. The results show that the depolarization of CCl4 Raman spectrum is closer to theory when using the high transmittance and high polarization for polarizer in narrow wavelength range; The performance of the analyzer effects little on the depolarization, but to reduce the effect, the transmittance and the polarization of the analyzer should be high and the curves are plat in the wavelength range of the measured material’s Raman spectrum.
