摘要
本文报道了建立的国内第一套激发光源在２２０ｎｍ～９７０ｎｍ连续可调谐的共振拉曼测量系统。详细分析了影响谱图信噪比的因素，提出了相应的抑制噪声的方法，优化了参数设置，测得了满意的谱图。
A set of resonance Raman spectrometer with excitation lines continuously tunable in 220—970nm,which is a first set in China,has been assembled.The factors influenced on the signal noise ratio(SNR)of spectra were analyzed in detail.The methods to improve the SNR were suggested and the parameters of the spectrometer were optimized.A satisfied Raman spectra can be obtained.
