Abstract

The reference objective lens includes an objective lens and an index member provided with an index that indicates a reference position. The index member is disposed on the front-side focal position of the objective lens or in its vicinity. Upon the reference objective lens thus configured being mounted on an apparatus having an image sensor, an image of the index that indicates a reference position is captured with the image sensor, and a position of the index in the captured image is calculated out and stored. Then, upon a predetermined optical system being mounted on the apparatus having the image sensor in place of the reference objective lens, aberrations of the optical system are measured, and the optical system is adjusted so that aberrations at a position that corresponds to the stored position satisfy a predetermined condition.
