摘　　要：提出在分光计上采用平行光掠射法测量透明光学材料折射率的方法,论述了该方法的实验原理,给出了测量公式,并详尽介绍了该方法的实验操作方法。同目前国内外所采用光学材料折射率测量方法相比,不但具有操作方便迅速、环境条件要求低的特点,而且所得谱线锐利清晰,谱线条数多,位置稳定,实验测量精度高等优点。Measuring refractive index of transparent optical material on spectrometer experiment by parallel light grazing method was proposed. The principle and the processes of the method were introduced and then the measurement formula was given. Compared with conventional methods for measuring refractive index of optical material measurement, this method is more convenient and easier to operate. Furthermore, this method has low environmental requirements, multiple spectral lines, and high measurement precision ; the spectral lines are sharp, clear, and stable.
