分光计的一种快速精确调节法

A Fast and Accurate Adjustment Method for Spectrometer

分光计是测量三棱镜折射率的主要仪器,使用中的难点在于调节望远镜主轴与仪器主轴的垂直关系.提出利用平面镜和三棱镜共同调节的方法,达到了实验的要求,相比单一用平面镜或三棱镜调节的方法,这种方法更快速,更精确.

The spectrometer is the main instrument for the experiment of measuring the reflection index of triangular prism.The difficult point in operation lies in adjusting the vertical relation between the main spindle of telescope and that of the instrument.The plane mirror and triangular prism are suggested to be used together for adjustment,and the result meets the requirement of the experiment.Compared with the method of adjustment used single plane mirror or triangular prism,this method is faster and more accurate.
