摘　　要：基于法拉第效应,在室温下,搭建实验光路,研究了入射光波长与法拉第偏转之间的关系,测得了实验样品MR3-2对不同波长的菲尔德常量,对菲尔德常量和波长关系进行拟合,拟合曲线与理论曲线符合较好.Based on the Faraday effect, an experimental light spectrometer was setup under low magnetic field and room temperature and the relationship between the wavelength of incident light and Faraday rotation angle was investigated. The Verdet constants of MR3-2 crystal sample under different wavelengths of incident light were obtained from the experiments. Furthermore, the relationship between Verdet constant and incident light wavelength was established by fitting analysis, and the experimental curves were agreed well with the theoretical results.
