Abstract

PURPOSE: To enable the emission quantity of a light source to be effectively used by disposing a photographing light source and an observing light source from the closer to the eye to be examined and disposing an optical member of the nature which shields visible light and passes invisible light.
CONSTITUTION: A photographing light source 15 and an observing light source 11 are disposed subsequently from the closer to the eye to be examined in the lighting system. Between these is disposed a filter 14 having the function of allowing the passage of only the wavelength region for observation of the nature of not causing the pupil to shrink, e.g., infrared light. At the observing, the eye fundus 24a is held lighted by the infrared light having passed through the filter 14. The reflected light having reflected on the eye fundus passes through the hole 21a of a holed mirror 21 and forms its image on an aerial imaging plane 28a as it is changed over by a moving quick-return mirror 27. This image is converted to an electric signal by a television camera 37 and the signal is then displayed as the visible eye fundus image in an image receiver 39. In addition, the eye funds 24a is lighted by the emission of a strobe tube 15, whereby the fundus image is formed on a film 28.
