Abstract
An optical system of an ophthalmologic imaging apparatus of embodiment splits light from a first light source into measurement light and reference light and detects interference light of returned light of measurement light from an eye and reference light. An image forming part forms an image based on detection result from the optical system. The optical unit includes a lens and joining member. The lens is locatable in an optical path of measurement light and used for changing a focus position of measurement light from a first site of the eye to second site. The joining member joins an optical path from a second light source to the optical path of measurement light. The optical unit converges light from the second light source having been guided into the optical path of measurement light by the joining member on an eye fundus via the lens.
