A Study on the Methods of Adjustment of Coaxialon in Determining the Focal Length of Thin Lens

结合二次成像法透镜焦距测定实验，研究总结出两种共轴调节方法，其特点是操作的指导思想明确，方法简单方便。

This paper reports two methods of adjustment of coaxialon determining the focallength of lens by means of double image-making. The clear guarding thoughts for operation, the simplicity and convenience are the characteristics of the two methods, with which the adjustment of coaxial can be obtained quickly and accurately.
