发明名称 OPHTHALMIC APPARATUS
摘要 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.

主权项 1. An ophthalmic apparatus comprising: 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 a pupil of an examinee's eye, the imaging optical system being configured to image a fundus image of the examinee's eye by use of the imaging device through the objective lens and the imaging diaphragm; a first light projecting optical system including a first light source to emit light having a first wavelength and being configured to project the light with the first wavelength, emitted from the first light source and restricted in range for passage through the pupil of the examinee's eye, as autofluorescence-inducing excitation light to the examinee's eye through the objective lens; and a first optical-path combining member configured to allow the imaging optical system and the first light projecting optical system to share at least part of an optical path with each other, wherein the first optical-path combining member is provided between the objective lens and a conjugate position to be conjugated with the pupil of the examinee's eye through the objective lens in the imaging optical system.
