Abstract
An ophthalmologic apparatus includes an objective lens, a refractive power measurement optical system, an inspection optical system, and an optical path separating unit. The refractive power measurement optical system is configured to project light in a first wavelength range onto a subject's eye via the objective lens and to detect returning light from the subject's eye. The inspection optical system is configured to project light in a second wavelength range onto the subject's eye via the objective lens. The optical path separating unit that is arranged in an optical path of the refractive power measurement optical system and is configured to separate an optical path of the inspection optical system from the optical path of the refractive power measurement optical system by performing wavelength separation based on changeable wavelength separation characteristics.
