【摘要】 介绍一种衍射光学透镜的通用设计方法，它适用于大的相对孔径和任意物像共扼距离，同时考虑了透镜基极厚度的影响。设计结果，用激光写入法加工成透镜，其成像质量达到衍射极限。更多还原

【Abstract】 A general mathod for designing diffraction lenses presented,It is adopotable to the diffraction lenses with large D/F and arbitrary conjugate distance,while effect of the subtracte thickness is taken into consideration. A lens thus designed was fabricated by 1aser writing system,the imagen quality is obtained diffraction limit.更多还原
