Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a wavefront aberration measuring apparatus capable of performing accurate wavefront aberration measurement.SOLUTION: A wavefront aberration measuring apparatus 1 includes: a relay optical system 31 for receiving light passed through a test lens 10 and converting the received light into parallel light; a wavefront sensor 41 for dividing and detecting the parallel light from the relay optical system 31; an analyzer 52 for finding out a wavefront aberration of the test lens 10 on the basis of a detection signal of the light divided and detected by the wavefront sensor 41; and a driving device 46 for moving the wavefront sensor 41 along an optical axis so that a microlens array 42 of the wavefront sensor 41 is located on a position conjugate with an exit pupil 11 of the test lens 10. |
