Fundus camera

A fundus camera for photographing a fundus of an eye to be examined, the fundus camera comprising:

• an illumination optical system for illuminating the fundus with visible illumination light for photographing and with invisible illumination light for observation;
• a photographing optical system, including a first image-pickup element which has sensitivity to a visible range, for picking up an image of the fundus with visible reflection light from the fundus;
• an observation optical system for picking up the image of the fundus with invisible reflection light from the fundus, the observation optical system including
• a wavelength-selecting mirror having a wavelength-selecting property of reflecting approximately all light within an invisible range and a part of light within the visible range and transmitting a large residual part of the light within the visible range, the wavelength-selecting mirror being disposed on a first optical path of the photographing optical system, and
• a second image-pickup element having sensitivity to the visible range and the invisible range, the second image-pickup element being disposed on a second optical path divided from the first optical path by the wavelength-selecting mirror;
• a fixation target projection optical system for fixating an eye, the fixation target projection optical system including
• a light-dividing member disposed on the second optical path of the observation optical system, and
• a fixation target light source for emitting visible fixation target light, the fixation target light source-being disposed in an approximately conjugate position with an image-pickup surface of the second image-pickup element on a third optical path divided from the second optical path by the light-dividing member;
• and
• a wavelength-selecting filter having a wavelength-selection property of transmitting approximately all the light within the invisible range and a part of light within the visible range and reflecting another part of the light within the visible range, the wavelength-selecting filter being disposed on the second optical path between the wavelength-selecting mirror and the light-dividing member in an approximately conjugate position with the image-pickup surface of the second image-pickup element,
• wherein the visible fixation target light is guided to the eye and photo-received on the second image-pickup element.
