分光计一种新的快速调节方法

A New Fast Adjustment Scheme of Spectrometer

分光计的调节是大学物理实验教学的一个难点,其中调节望远镜光轴垂直于分光计中心轴耗时最长。针对这一问题,该文提出分光计一种新的快速调节方法。该方法巧妙使用水准仪正确判断十字像的位置,从而能分别迅速地找到三棱镜两个光学面中的十字像。该方案易于被初学者理解和掌握,可使初学者在约半个小时之内完成整个分光计的调节。

The adjustment of spectrometer is one of the difficulties in college physics experiment teaching. Adjusting the optical axis of the telescope to be perpendicular to the central axis of the spectrometer is the most time consuming procedure. To solve this problem, a new tast adjusting method of spectrometer is proposed in this paper. This method cleverly uses the level to con＇ectly judge the position of the cross image, so that the cross images of the three prisms in two optical planes can be fimnd quickly. This method is quite easy to be understood and mastered by the beginners, and can make the beginners finish the whole adjustment oi＂ spectrometer in about a half hour.
