摘要
透镜组的基点在几何光学中占有重要的地位.对平行光束中不同的入射光线经过透镜组后的出射情况进行分析,讨论了透镜组像方节点到测节仪转轴不同距离时的成像规律和用测节仪测量透镜组基点的方法,以加深对透镜组基点的理解和用测节仪测量透镜组基点的认识.
The cardinal points play an important role in the geometrical optics. The spread of optical imaging is analyzed when a collimated light beam passes through a compound lens,then the image rule is discussed when the rotational axis of the nodal slide does not coincident with the image nodal point,and the measurement method of cardinal points of a compound lens is presented. These can be used to deepen students＇ comprehensive understanding of the cardinal points of compound lens and measurement with nodal slide.
