A method of measuring an optical characteristic of an optical system using a measurement apparatus, comprises determining a position of each of object points by arranging, on a side of the object plane, an object point measurement device array, and sequentially inserting the object point measurement devices in an optical path, determining a position of each of image points by arranging, on a side of the image plane, an image point measurement device array, and sequentially inserting the image point measurement devices in the optical path, calculating an error attributed to the measurement apparatus based on the positions of object points and the positions of the image points, obtaining a measured value by measurement to obtain information representing the optical characteristic of the optical system using the measurement apparatus, and correcting the measured value based on the error.
