The wave - deviation methods are concerned , basing on the relations between the wave - deviation and spherical aberration , wave - color - deviation and color deviation . after the equation of optical system , initial structure resolved , the glass catalog having been allocated in the computer , the original solution can be worked out for the doublet and air - spaced doublet , triplet and air - spaced triplet rapidly and precisely . after a little modification by the computer , the satisfied results will be obtained
论文由波像差与球差的关系，波色差与色差的关系推导出了波差法求解光学系统初始结构的方程式，再配以玻璃库程序，可以较快、较准确地求解出双胶合、双分离、三胶合、三分离物镜的初始解，然后再进计算机稍加校正，就可以得到满意的结果。
