摘　　要：建立了一组既消位置色差又消二级光谱的方程组 ,即复消色差方程组 同时引入了规化位置色差系数L和规化二级光谱系数S的概念 ,得到了对复消色差光学系统设计中的玻璃选择具有指导意义的S L图An equation set for apochromatic system has been formulated, which can eliminate longitudinal chromatic aberration and secondary spectrum. At the same time, the normalized coefficient L of longitudinal chromatic aberration and normalized coefficient S of secondary spectrum of optical materials are introduced. With the help of the instructive S L chart, suitable optical materials for the design of apochromatic system can be selected effectively. Finally, design examples of apochromatic system composed of three thin lenses or Petzval objective are given in this article.
