“三位水平法”快速调节分光计

摘要

Structure of spectrometer is very precise. Technique of adjusting spectrometer is one of the basic skills of optical experiment. Adjusting optical axis of the telescope is perpendicular to spectrometer’ s axis of rotation is the most difficult process. When measuring prism’ s index of refraction,adjusting optical axis of the telescope is perpendicular to prism’ s plane of refraction is the other trouble. This paper will introduce how to solve the problem by round level bubble. The way is simple and easy to operate.%分光计构造精密，它的调节技术是光学实验中的基本技术之一。应用分光计测定棱镜折射率时，仪器的调节存在两个难点。在此介绍借助圆水准泡，应用“三位水平法”快速解决这两个难点，方法简单、易操作，可在物理实验教学中应用。
