By chiseling a BOL on a surface of a lens, a apochromatic system is composed, which actualizes the system's apochromatism, as well as revising primary aberration.

并光学面刻画在透镜表面，在校正系统初级像同时，实现了系统复消色。

The principle of secondary spectrum is introduced and the equations of designing apochromatism objective lens based on wave aberration are presented.

介绍了级光本原理,给出了波法设计复消色物镜方程组。
