Claim Text:
1. A method for measuring a lens, the method comprising the steps of: a) placing the lens inside an inner volume of a cuvette; b) acquiring an image of the lens using an image sensor; c) calculating the diameter of the lens and location of a center of the lens from the image of the lens; d) positioning an optical probe of a low coherence interferometer to direct a first beam of light along an axis passing through the lens proximate to the center of the lens; e) measuring optical thickness of the center of the lens with the low coherence interferometer; f) emitting a second beam of light from a light source directed through the cuvette and lens and onto a lenslet array of a Shack-Hartmann wavefront sensor, the second beam of light surrounding the first beam of light; g) measuring wavefront deviations of the second beam of light caused by the lens using the Shack-Hartmann wavefront sensor; and h) calculating at least one optical performance parameter of the lens.
