Abstract:
A fundus photography device includes: a fundus illumination optical system that illuminates a fundus of an eye by illumination light; a fundus photography optical system; an OCT optical system; an anterior chamber observation optical system for observing an anterior chamber observation image of the eye illuminated by the anterior chamber illumination light source; a first wavelength separation member that sets a first optical axis commonly shared by the fundus illumination optical system and the fundus photography optical system to be coaxial with a second optical axis commonly shared by the OCT optical system and an anterior chamber observation optical system; and a second wavelength separation member that forms the second optical axis by setting an optical axis of the OCT optical system to be coaxial with an optical axis of the anterior chamber observation optical system.
