为了用机器视觉检测技术精确检测微小零件的几何轮廓误差，设计了一套高分辨率非球面双远心物镜。根据检测要求确定系统的光学参数，运用架构分析法对系统进行整体光学初始结构设计。运用 Zemax 光学设计软件对初始结构进行优化，在物镜设计中引入非球面，使结构简化，并有效的平衡系统像差，提高像质。实现了低畸变（最大畸变小于一个像素）、高分辨率（在奈奎斯特频率 90.9lp/mm 处 MTF 值优于 0.7，全视场 400lp/mm 处 MTF 值达到 0.15）和双远心系统的设计要求。
In order to accurately detect the geometric contour errors of the tiny parts by using the machine vision detection technology, a set of high resolution aspheric double telecentric lens was designed. According to the testing requirements to determine the optical parameters of the system, the use of architectural analysis of the overall system of optical initial structure design. The use of Zemax optical design software to optimize the initial structure, the introduction of aspheric lens design, so that the structure is simplified and effectively balance the system aberrations and improve image quality. Achieved low distortion (maximum distortion less than one pixel), high resolution (better than 0.7 at a Nyquist frequency of 90.9 lp / mm and a MTF of 0.15 at a full field of view of 400 lp / mm) and dual telecentric system The design requirements.
