Measurement cannot be made when trying to measure a wavefront aberration of a wide-angle lens, being wide in a field of view, comparing to a focus distance, by a Shack-Hartmann sensor, since an inclination of the wavefront exceeds an allowable value of inclination of the Shack-Hartmann sensor. The Shack-Hartmann sensor is inclined at a position of a pupil of a lens, and is controlled so that it lies within the allowable value mentioned above. Photographing is made through step & repeat while overlapping at the same position, to compose in such a manner that overlapping spots are piled up, and thereby measuring the wavefront aberration of the lens having a large pupil diameter.
