为了更准确地评价渐进多焦点镜片(PAL)的设计结果,采用Zemax对渐进多焦点镜片进行评价。结合一个光焦度增量为2.5 m-1的渐进镜片实例,辅以MatLab软件,计算出镜片表面参数,以及球面度和柱面度的理论分布图。然后将镜片参数导入Zemax,获得球面度和柱面度的仿真结果,与理论分布图比较,得出更准确的评价结果,说明Zemax能更准确、全面地评价渐进镜片。

To evaluate the performance of the progressive addition lenses (PAL) the evaluation of PAL based on Zemax is emphasized. As an example, a PAL with 2.5 m-1 addition is calculated by MatLab to obtain lens parameters, theoretical spherical and cylinder power. Import lens parameters into Zemax and get spherical power and cylinder power to compare with the theoretical ones to illustrate that Zemax can evaluate PAL more accurately and completely.
