摘　　要：在对加工完毕的渐变焦眼镜进行测量时,现有的镜片测量设备无法集精度、稳定和方便于一身。文中系统采用哈特曼夏克传感器(Hartmann-Shack Sensor,HSS)作为测量核心,使用F550平行光管作为光源,并使用单透镜对光线进行缩小,使其恰好进入哈特曼夏克传感器,实现光瞳衔接。用QT编写测量软件用于采集测量数据,得到Zernike系数,最后求得镜片的光焦度值以及散光值。将通过此系统采集到的数据和中国万新光学集团所检测到的数据相对比,数据基本一致,验证了该系统的精确性和可靠性。The existing equipment can t obtain precision,convenience and stable at the same time when measuring the processed lens,so design this system.using Hartmann-Shark sensors to collect the data,using F550 Collimator as the light source,and using Single lens to narrow the light beam,realize the connection between two pupils.Write software through the QT to collect the data,the Zernike coefficients are obtained,finally we get value of focus the focal power and the value of astigmatism.The dates collect by this system is basically the same with the datas detected by Wanxin Optical,the accuracy and reliability of the system are verified.
