| 摘 要： | 本文分析了一种折射率为球对称梯度分布的球形透镜的像差，得到了该透镜对无限远物点的纵、横向球基及其焦距的精确表达式。严格的数值计算表明，该类透镜的像差明显小于通常的均匀折射率球形透镜，若合适地选取参数，可使前者的像差比后者减少一、两个数量级。

| Abstract: | In this paper the aberrations of a sort of sphere lens with spherical Symmetrical gradient index have ben analysied. The accurate expressions to calculate the focal length and their longitudinal and transverse spherical aberrations on infinite objective point have been obtained. The rigorous numerical result shows that they have much smaller aberrations than the ordinary sphere lens with homogeneous index, while in suitable parameters the former is even smaller than the latter by one or two order of magnitude. |
