针对传统V棱镜折射仪采用光学度盘，目视对准方式无法满足现代光学玻璃生产线以及高精度折射率测量的需求。提出一种新型的高精度基于CCD 机器视觉对准的V棱镜折射仪的总体设计方案，并对准直光管、传动机构、锁紧和微调机构以及轴角编码测角机构等主要组成部分进行了光机结构设计。在考虑空气折射率影响因素的修正公式的基础上，分析了仪器的检测误差。实验结果表明：其折射率检测精度可达3×10-6，满足了高精度V 棱镜折射仪的技术指标要求。

For the problems that the traditional V-prism refractometer employs the optical dial and the visual alignment is unable to meet the demands for the production line of modern opti-cal glass and high-precision refractivity measurement ,a kind of new general design scheme of high precision V-prism refractometer based on charge-coupled device (CCD) machine vision a-lignment was put forward in this paper ,and the optical and mechanical structure design of the main components of the system ,such as collimator ,transmission mechanism ,locking and fine adjustment mechanism ,orientation measuring mechanism of shaft encoder was done .Addition-al ,the detection error of the instrument was analyzed on the basis of the correction formula considering the air refractive index factors .The results show that the refractive index test ac-curacy reaches up to 3 × 10-6 ,the technical index requirements of the high accuracy V-prism refractometer are well satisfied .
