CUVETTE FOR OPHTHALMIC LENS

摘要

Modified MZ (Mach-Zender) interferometers are utilized to analyze the tra nsmitted, 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 conf iguration. Reverse raytracing is utilized to remove aberrations induced into the wavefront as it is imaged from immediately behind the lens to the detec tor of the interferometer.
