Abstract

An apparatus and method for measuring wavefront aberrations. The apparatus comprises a magnification device for magnifying the wavefront, a wavefront sensor for capturing information related to the magnified wavefront, and a processor for calculating aberrations of the wavefront from the captured information. The method comprises receiving the wavefront emitted from the pupil at an adjustable lens assembly, adjusting the magnification of the adjustable lens assembly such that the magnified wavefront is optimized for use with the wavefront sensor; and passing the magnified wavefront to the wavefront sensor.
