一、引言本文不是从GRIN棒透镜的材料本身的物理化学性能上来分析自聚焦透镜的损耗,而着重于分析自聚焦透镜的损耗与其光学工艺指标的关系。随着光通信技术的发展,自聚焦透镜在微型光学的各种无源器件中的应用越来越广,其地位已达到了相当的水平。这样,对自聚焦透镜的各种参数将如何认识,它们与损耗之间的关系如何,已成 I. INTRODUCTION This article does not analyze the loss of a self-focusing lens from the physicochemical properties of the material itself of a GRIN rod lens but focuses on analyzing the relationship between the loss of a self-focusing lens and its optical specifications. With the development of optical communication technology, the position of self-focusing lens has reached a considerable level in various passive components of micro-optics. In this way, the self-focusing lens of the various parameters will be how to know their relationship with the loss has become
