Abstract

PURPOSE:To obtain an infrared fluorescent eyeground image having sufficient brightness, by converting a ring-shaped opening iris to a circular opening iris having an axial region opening part corresponding to the insertion of an infrared filter in an illumination system. CONSTITUTION:An illumination system 1 has an observing beam source lamp 2, an infrared filter 5, a condensing lens 3, a half mirror 4, an infrared exciter filter 6, an iris plate 12, a partial mirror 14, a reflecting mirror 16 and a relay lens 18. At the time of general imaging, the infrared exciter filter 6 and an infrared barrier filter 72 are separated from an optical axis, and a ring slit plate 54 and a circular opening iris 71a having a small opening diameter are inserted on the optical axis and the beam source lamp 2 is allowed to light in small quantity of beam. At the time of the infrared fluorescent imaging of the eyeground, the infrared exciter filter 6, a circular aperture iris plate 56 and the infrared barrier filter 72 are arranged on optical axes 8, 70 and the circular opening iris 71b having a large opening diameter of an iris plate 71 is inserted in a beam path and the quantity of the beam emitted from the beam source 2 is increased.
