Abstract: The existing equipment can not 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.

Key words: progressive multifocal lens;measurement system;Hartmann-Shack sensor;F550 collimator;focal power;astigmatism
