摘要
DVD光学读数头是新一代的高密度光盘系统的核心部件。本文在分析并确定 DVD光学头读出物镜的参数后 ,设计出了满足这种特殊要求的双面非球面读出物镜 。
Optical pick-up is the cut-in point of DVD system. In this paper, The parameters of the pick-up objective lens for DVD system are analyzed. A single-element with two aspheric lens is designed for the special need, and the effects of every unit' error to the system' quality are studied.
