摘要
在分光计的调整实验中,需要调整望远镜光轴与分光计的中心轴垂直,这一步是最关键、最困难的步骤.对于实验中经常出现的只能观察到一个"十"字叉丝反射像的问题,从光路上进行了详细的分析,提出了一个新的简单有效的调整方法,还给出了调整望远镜的完整流程图.
It has need to adjust optical axis of telescope perpendicular to central axis of spectrometer in the experiment of spectrometer.This is very crucial and difficult.A detailed analysis of geometrical optics is presented for the problem of only seeing one reflected cross-shaped image that often appears in the experiment.A new method is developed for resolving this difficult problem,and proved to be easy and effective.In addition,a flow chart of adjusting telescope is presented.
