Abstract: A fundus camera being capable of moving a fixation target surely and precisely to a position intended for photographing with an adequate degree of freedom for moving the fixation target. The fundus camera is provided with an observation optical system having an objective lens and a photographing element for photographing a fundus illuminated with illumination light, a monitor on which an image of the photographed fundus is displayed, a fixation-target presenting optical system for presenting a fixation target via the objective lens, a fixation-target moving unit by which a position to present the fixation target is shifted to a desired position, a first display-control unit by which the position of the fixation target is superposed on the fundus image to be displayed on the monitor, and a second display-control unit by which a guide target for moving the fixation target is displayed in a predetermined position on the monitor.

Abstract: A fundus camera having a simplified unit mechanism having a fixation light disposed at a suitable position for efficiently guiding a sight line, the fundus camera comprising an illumination optical system for illuminating a fundus of an eye to be examined with visible illumination light for photographing and with invisible illumination light for observation, a photographing optical system having a first photographic element, for photographing an image of the fundus with visible reflection light from the fundus, an observation optical system having a second photographic element for photographing the image of the fundus with invisible reflection light from the fundus, a wavelength-selecting mirror dividing light into invisible light, a part of visible light, and most of the visible light, a light-dividing member further dividing the optical path of the observation optical system, and a fixation target disposed on the optical path divided from the optical path of the observation optical system by the light-divid

Abstract: A fundus camera according to the present invention is capable of facilitating observation, color photographing and fluorescent photographing without complicating operations and components of the device. The fundus camera is provided with a first illumination optical system for illuminating a fundus of an eye to be examined with infrared light for observation, a second illumination optical system for illuminating the fundus of the eye with visible light for photographing, a photographing optical system for photographing an image of the fundus with visible reflection light,from the fundus, and an observation optical system for observing the fundus in the infrared reflection light from the fundus. The observation optical system includes an optical path shared with the photographing optical system and an optical path branched from the optical path of the photographing optical system by a first wavelength-selecting mirror.
