PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of further stably and accurately specifying a position of a measuring object site inside a subject's eye, thereby capable of providing highly reliable data.SOLUTION: The ophthalmologic apparatus according to the present application comprises a calibration optical system including: a first optical path in which the optical path length from a zero point where the optical path length of a reference optical system becomes same as the optical path length of a measurement optical system, is a first optical path length; and a second optical path in which the optical path length from the zero point becomes a second optical path length. In the calibration optical system, the optical path length of the first optical path is set shorter than an optical path length from the zero point to a position of a first site that is closest to the zero point of the measurement object site. The optical path length of the second optical path is set longer than an optical path length from the zero point to a position of a second site that is farthest to the zero point of the measurement object site.SELECTED DRAWING: Figure 1 |
