摘　　要：本文从分析空气中的单棱镜的角色散出发,得出了三种提高棱镜摄谱仪色散效果的方法,即入射光偏离棱镜最小偏向入射角入射,增大初始色散和使光束多次通过棱镜。对前两种方法,在WPL小型棱镜摄谱仪上进行了实验,分别使谱仪的线色散增大0.2倍和4倍。By studying the angular dispersion of a single prism in the air, we get three methods of making the angular dispersion of a prism spect rograph larger, incident beam being deviated from incident angle of prismatic miaimum deviatior, increasing primary dispersion and making incident beam pass through the prism many times, We do experimeets with the small prism spect rograph model WPL by the first and the second methods, these make the linean dispersion of this spectrograph 0. 2 times and 4 times larger.
