摘要

双远心镜头所具有的低畸变、大景深等优点，与机器视觉中高成像质量和多场景应用需求相匹配，利用Zemax仿真设计了一款可用于机器视觉的高分辨率双视场双远心镜头。将该双远心系统分为固定结构和可拆卸结构的两部分，通过翻转可拆卸结构，即可在保证高分辨率和高远心度的同时改变系统的光学放大率，提高了远心镜头在多个应用场景的适用性。所设计的具有双视场双远心镜头在可见光波段（486~656nm）内，平均弥散斑半径小于9µm，各视场远心度均小于0.015°，畸变率低于0.1%，调制传递函数在75lp/mm时大于0.4，各视场波像差均小于

Abstract

The dual-telecentric lens features advantages such as low distortion and large depth of field

which match the requirements for high imaging quality and multi-scenario applications in machine vision. A high-resolution dual-field double telecentric lens suitable for machine vision was designed and simulated using Zemax. The double telecentric system wa

s divided into two parts: a fixed structure and a detachable structure. By flipping the detachable structure

the optical magnification of the system could be changed while maintaining high resolution and high telecentricity

improving the applicability of the telecentric lens in multiple application scenarios. For the designed dual-field double telecentric lens within the visible light wavelength range （486~656nm）

the average spot radius is less than 9µm

the telecentricity in both fields of view is less than 0.015°

the distortion rate is lower than 0.1%

the modulation transfer function is greater than 0.4 at 75lp/mm

and the wave aberration in both fields of view is less than
