三棱镜色散系数研究

摘要

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.%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。
