摘要
一、引言当蓝光光盘(BD:Blu-ray Disc)标准确立以后,对可兼容读取BD、DVD和CD光盘的多功能物镜的需求迅速增加。为了实现兼容读取多种类型的盘片,
We have developed an objective lens which can be used for different optical disk formats-Blu-ray Disc,DVD and CD.The compatible technique is based on the diffraction characteristics optimized by tuning refractive index dispersion.This optical configuration can provide suitable designs for optical pick-up system of high speed recording.
