摘要
根据不同波长对同一棱镜的折射率不同,使用棱镜作为"色散系统"实现分光,测量了汞灯各色光对棱镜的折射率,利用最小二乘法研究得到样品棱镜的色散系数。
According to refractive index of different wavelengths on the same prism is different, the beam is separated using the prism as ＂dispersion system＂. Refractive index of Mercury lamp＇ s different wavelengths on the triple prism was measured. The dispersion coefficients of the triple prism were obtained by using the least square method.
