Abstract
Provided is an ocular optical system, which permits a measuring beam scanned by two scanning units disposed close to each other to enter an anterior ocular segment of an eye to be inspected and to irradiate a fundus. The ocular optical system includes an optical unit which is disposed at a position of an intermediate image, which is optically conjugate to the fundus, and has a surface having different optical powers corresponding to scan directions of the two scanning units.
