摘　　要：为了详细了解洛匈棱镜的分束角特点,该文根据冰洲石晶体中e光波主折射率的色散关系及e光波遵守的折射定律,从理论上推导出了洛匈棱镜用于不同光波长和不同入射角时分束角的计算公式;利用3种激光光源对其光谱效应与入射角效应进行了实验测试,结果表明:入射光波长与光的入射角均对洛匈棱镜的分束角产生影响.对于结构角一定的洛匈棱镜,当入射角一定时,分束角随入射光波长的增大而减少;当入射的光波长一定时,分束角随入射角的变化而变化,光的入射角为负值时对棱镜分束角的影响较小,为正值时对棱镜分束角的影响较大,且入射角越大影响越明显.Based on the dispersion of the main index of refraction of the e light and the law of refraction of the crystal of Iceland Spar,the thesis theoretically dedues the splitting angle＇s formulae with the Los austro-hungarian prism in different optical wavelengths and angles of incidence,studies the splitting angle＇s features of the Los austro-hungarian prism in detail.The results from the experimental tests in which our panel utilize three kinds of light source of laser to test the spectral effects and the angle of incidence effects demonstrates that wavelength and the incident angle of light affect on the splitting angle.For the Los austro-hungarian prism with a certain structure,the splitting angle decreases as the wavelength increases when the angle of incidence remains unchanged,while the splitting angle varies as the angle of incidence does for a certain wavelength,especially when the angle of incidence is a negative figure,the varying will be less affected,and it is in the contrary in turn.
