载物台优先调节的分光计调节方案探讨

Discussion on Adjustment Scheme of Spectrometer with Priority Adjustment of Stage

本文分析了分光计的载物台和望远镜分别偏离正常位置时像的位置分布特征,总结了优先调节载物台,再进行望远镜倾角调节的方案。该方案可以避免细调实践中学生容易把分光计视野中绿十字像调出视野的现象。同时,该方案也可以推广到粗调环节,解决粗调时目测粗估调好但在望远镜中仍看不到绿十字像的困扰。由于载物台和望远镜的偏离对应的像的位置特征明显不同,容易辨别掌握,可以有效提高分光计的调节效率,有助于改善分光计相关实验项目的教学进程。

The image position distribution characteristics when the spectrometer stage and telescope deviate from the normal position were respectively analyzed,and the scheme of adjusting the carrier stage first and then adjusting the telescope angle was summarized.This scheme can avoid the phenomenon that the Green Cross image in the spectrometer field of view is easily out of the field of view in the fine tuning practice.At the same time,the scheme can also be extended to the coarse adjustment link to solve the problem of coarse adjustment.The problem of green cross still can’t be seen in the telescope.Because the position characteristics of the image corresponding to the deviation of the stage and telescope are obviously different,it is easy to be distinguished and be mastered,which can effectively improve the adjustment efficiency of the spectrometer,and help to improve the teaching process of spectrometer related experimental projects.
