摘要:
The present invention relates to a fundus camera or a fluorescent fundus camera provided with a target for fixing the internal gaze for aligning the visual axis of the eye and the detector axis of the fundus camera or the fluorescent fundus camera, and accurately photographs the macula and fovea when taking a fundus photograph or a fluorescent fundus photograph The present invention relates to a fundus camera or a fluorescent fundus camera provided with a target for fixing the internal gaze without increasing the optical path provided so that the desired peripheral part can be accurately photographed, but does not generate an additional optical path and does not cause a decrease in performance or size change of the entire optical system. . A fundus camera or a fluorescent fundus camera provided with a target for fixing the internal gaze without an increase in the optical path according to the present invention is a target optical system for fixing the gaze of a person, wherein the target optical system uses light to fix the visual axis of the person. Emission target 23; A target illumination lens 24 provided behind the target 23 on the same axis as the target 23 to receive light emitted from the target 23; A target control provided so that the target 23 and the target lighting lens 24 are parallel to the target lighting lens 24 on the same axis as the target lighting lens 24 so that the light drawn from the target lighting lens 25 is located within the focal length of the lens. It consists of a lens 25; An illumination unit 10 for emitting light to the target optical system; An illumination lens 30 provided behind the target illumination lens 24 on the same axis as the target illumination lens 24 to irradiate the target 23 and the light received from the illumination unit 10 at a predetermined emission angle; A beam splitter (50) provided on an axis parallel to the illumination lens (30) and splitting the light received from the illumination lens (30); And an object
