易测量非球面定义及应用（英文）

Definition and application of easily measurable aspheric surfaces

本文提出了一种新型、易于用传统光学干涉仪测量的非球面。该非球面的检测主要基于Zemax光学程序软件设计的多重配置特性。第一配置为易于测量非球面,第二配置为采用平行平面玻璃板或单透镜作为零位校正器,用于检测第一配置的非球面。本文通过一些实例,说明了易测量非球面检测技术的应用和优势,证实了与圆锥或普通非球面相比,易测量非球面更易于操作与检测,同时有利于减小光学像差。

This paper presents a new kind of ＂Easily Measurable Aspheric Surfaces＂（ EMAS）,which could be easily measured by a traditional optical interferometer. The measurement of EMAS is mainly based on using the multi-configuration feature in Zemax software. The first configuration represents the optical system with EMAS,and the second configuration represents the setup,using a parallel planes glass plate or a single lens as a null corrector to measure the aspheric surface used in the first configuration. The applications and advantages of this technique are illustrated by many examples,which could confirm the ease of manipulating and testing this kind of surfaces,compared with conical or general aspheric surfaces. It can also show its competence in minimizing the optical aberrations.
