Abstract:
A fundus capturing apparatus, comprising: an irradiation unit adapted to irradiate light through an illumination light path onto a fundus of an eye to be examined; a capturing unit adapted to capture a fundus of the eye to be examined with reflection light of the light irradiated by the irradiation unit; a focus confirming unit adapted to confirm a focus state of the fundus captured by the capturing unit, the focus confirming unit being arranged on the illumination light path; a moving unit adapted to move the focus confirming unit on the illumination light path along a guide axis that is parallel to the illumination light path, in accordance with the focus state; and an advancing/retracting unit adapted to insert the focus confirming unit into the illumination light path or retract the focus confirming unit from the illumination light path by rotating it with respect to the guide axis.
