INTERFEROMETRY TESTING OF LENSES, AND SYSTEMS AND DEVICES FOR SAME |
摘要 |
<p>Modified MZ (Mach-Zender) interferometers preferably are utilized to analyze the transmitted, aspherical wavefront of an ophthalmic lens by mounting the lens in a cuvette having a rotatable carousel that can hold multiple lenses. Fresh, temperature controlled, saline solution is circulated about the lenses, and the cuvette is positioned in a vertical test arm of the interferometer configuration. Reverse raytracing preferably is utilized to remove aberrations induced into the wavefront as it is imaged from immediately behind the lens to the detector of the interferometer.</p> |
