Abstract
An ophthalmic apparatus includes: an imaging optical system including an imaging diaphragm placed between an objective lens and an imaging device to restrict light from a fundus, the light having passed through a position conjugate with an examinee's pupil, to image a fundus image by the imaging device through the objective lens and the imaging diaphragm; a first light projecting optical system to project light having a first wavelength emitted from a first light source and restricted in range for passage through the pupil, as autofluorescence-inducing excitation light to the eye through the objective lens; and a first optical-path combining member to allow the imaging optical system and the first light projecting optical system to share at least part of an optical path. The first optical-path combining member is provided between the objective lens and a conjugate position with the pupil through the objective lens in the imaging optical system.
