提出对光波导短程透镜传输理论进行系统研究的思想，推导出短程透镜基点（包括焦点和主点）、主面与焦距的表达式．研究了其焦点、主面的特殊性质，并与传统光学透镜的有关参量进行对比，得出消球差短程透镜不仅对近轴光线，而且对离轴光线均可实现理想聚焦，以及主平面为一段圆弧的特性．这一工作为短程透镜系统传输理论的建立打下了基础，适用于含短程透镜的系统设计与计算．
The idea of systematic research on the transmission theory of optical short-wave lens is put forward. The expression of the base point (including focal point and main point), principal surface and focal length of the short-distance lens is deduced. The focal point and the special properties of the principal plane are studied. Compared with the related parameters of the traditional optical lens, the conclusion is drawn that the aspheric short-range lens can achieve ideal focusing not only for the paraxial rays but also for the off-axis rays, A section of arc characteristics. This work laid the foundation for the establishment of transmission theory of short-range lens system, which is suitable for system design and calculation with short-range lens.
