摘要
本文分析了用一次离子交换工艺制备的自聚焦透镜的径向折射率分布规律，讨论了所能获得的最佳分布工艺条件．在此基础上提出了两步离子交换的新方法．
In this paper,the law of radial index distribution in the thallium glass selfoc lens manufactured by one step ion exchange technique has been analyzed.The optical distribution with this method and its technical conditions have been constructed.And a new way of exchanging ions in two steps has been proposed.Calculation shows that the selfoc lens manufacturing with this new method has a greatly improved index distribution.
