We discuss oblique spherical aberration, its balance, and its control. Several ways to mitigate this aberration are listed and some lens design examples are presented. The variation of oblique spherical aberration as a function of index of refraction and the shape factor of a thin lens is also presented. It is argued that controlling the amount and distribution of spherical aberration propagating in a lens system can be an important mechanism for mitigating oblique spherical aberration. The control of oblique spherical aberration is illustrated with a double Gauss lens, with lenses for microlithography, and with a lens for mobile phones.

教学镜头设计：斜球差特性及控制

我们讨论斜球面像差、其平衡及其控制。列出了减轻这种像差的几种方法，并提供了一些镜头设计示例。还介绍了斜球面像差随折射率和薄透镜形状因子的变化。有人认为，控制在透镜系统中传播的球面像差的数量和分布可能是减轻斜球面像差的重要机制。斜球面像差的控制以双高斯透镜、微光刻用透镜、手机用透镜为例进行说明。
