Investigation on the Entrance Slit Width and Exit Slit Width of Grating Spectrometer on the Measured Spectral Line Width

根据光栅光谱仪衍射方程分析研究了光栅光谱仪入射与出射狭缝宽度对测量谱线宽度影响,研究结果表明光栅光谱仪入射与出射狭缝宽度与测量谱线线宽间满足线性关系,并对理论分析结果进行了实验验证,理论与实验基本符合。

The influence of the entrance slit width and exit slit width of grating spectrometer on the measured spectral line width is experimentally and theoretically investigated respectively. The investigation resuits show that the measured spectral line width is linearly dependent on the entrance slit width and exit slit width of grating spectrometer. There is a well agreement between the experimental results and theoreticalresults.
