摘　　要：介绍了用离子交换法制作铊型自聚焦透镜及其干涉片工艺,通过对经过不同交换时间的自聚焦透镜的折射率分布的测试及成像特点的分析,得出透镜离子交换时间与交换深度、折射率分布的关系,由此确定用离子交换法制作自聚焦透镜的最佳离子交换时间.This article introduces the technology for producing thallium-self-focusing lenses and its interference in films with the ion-exchange method. The optimal time of ion exchange for self-focusing lens production is determined by analyzing the relationships between ion-exchange time and exchanging depth and between ion-exchange time and refractive index distribution.

关 键 词：自聚焦透镜 离子交换 折射率分布
