快速找到分光计十字像的一种简便方法

A Simple Way to Quickly Find the Spectrometer Cross Image

分光计是精密测量角度的光学基本仪器,其操作较为复杂,尤其是平面镜反射像不在视场出现,学生往往举足无措,本文提出了一种快速找到十字像的方法,“两眼并用”找到十字反射像,并结合光路分析了该方法的理论依据。

The spectrometer is a basic optical instrument for precise measurement of angle,and its operation is complicated,especially when the reflection image of plane mirror is not in the field of view,students are often at a loss for what to do.
