摘要
分光仪是一种能精确测量角度的典型光学实验仪器。在大学物理实验中,分光计的调节和使用是一个重要光学实验。由于分光仪结构较复杂,调节难度较大。其中最关键、最困难的一步是:如何调节望远镜光轴及载物台台面分别与仪器转轴垂直。针对这一难点,文中提出一种简单、快速的调节方法。粗调时使载物台台面紧贴台基,以保证载物台台面基本水平,细调时以望远镜调节为主,载物台调节为辅。
Spectrometer is one kind of instrument that can measure angles accurately.The adjustment and usage of spectrometer is one of the most important optics experiments in all of the college physics experiments.The adjustment of the spectrometer is difficulty because of the complicated structure.One of the most significant and difficult step is to adjust the optical axis of the telescope so that it can be perpendicular to the instrument shaft.In order to solve this problem,a simple and rapid method of adjustment is proposed in the paper.That is,adjust the instrument roughly to guarantee the Carring-thing platform in level with the floor,then in the fine one,the adjustment for the telescope will be took as a main task and for the carring-thing platform as a minor one.
