摘要： 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.

摘要： PURPOSE: To exclude observation photographing with inappropriate exposure due to the difference of a setting condition caused by the difference of physical properties and the forgetting of a restoring operation, by providing an inspection condition switching means which automatically changes an inspection condition under functioning, in a device which performs the inspection of a vital eye and that of an artificial eye. CONSTITUTION: When the observation photographing is performed for the inspection of the vital eye E, appropriate observation light quantity is inputted by an observation light quantity input part 14a, and appropriate photographing light quantity is inputted by a photographing light quantity input part 14b, and the sensitivity of a working film is inputted by a sensitivity input part 14c, then, an objective mirror barrel 2 is confronted with the vital eye E. When the vital eye E is observed, a light source 12 for observation is put on, and illumination light is reflected in the direction of vital eye E by a perforated mirror 3 via a relay lens 10, which illuminates the eyeground Er. When the photographing is performed, a movable mirror 6 is switched to a chain line position, and a light source 11 for photographing emits light, and an eyeground image is recorded on the film 7. When the artificial eye is observed, appropriate light quantity is selected for the artificial eye A by an inspection condition switching part 15, and a display part 16 is put on in a red color R.

摘要： PURPOSE:To perform both functions of observation and photographing by the same light source by providing a photographing device with a light adjustment means adjusting the illumination light from the light source of consecutive lightening to the light of low light quantity at the time of observation and an invalidating means obtaining the light of high light quantity without functioning the light adjustment function of the light adjustment means at the time of photographing. CONSTITUTION:At the time of observation, the illumination light from an illumination light source 11 passes filters 12 and 13 and is converged near a pupil part Ei through an objective lens 19 or the like. An eye fundus Ef is irradiated with the infrared light. Then, the reflection light from the eye fundus Ef is taken by a television camera 31 through an objective lens 19, image formation lens 25, and television lens 30 and the image of the eye fundus is displayed on a television monitor 33. On the other hand, a mobile mirror 26 is shifted to the dotted line position at the time of photographing. By rotating a solenoid 21, an arm 22 is shifted in the direction of the dotted line position and a mobile block 23 is moved upward. Thus, the filters 12 and 13 are retracted from the illumination optical path and the eye fundus Ef is illuminated with the bright visible light. The image of eye fundus is photographed by opening a shutter 27 and guiding the reflection light to a film 28.
