とを特徴とするベッドサイド用眼底カメラ。A fundus camera with an optical system in which an observation photographing optical system and an illumination optical system are coaxial and an objective lens made of an aspherical optical system is disposed to remove reflected light harmful to observation photographing, wherein the illumination optical system is The observation illumination light source and the photography illumination light source are provided along the optical axis L1 pointing upward, and a mirror or prism is provided above the optical axis L1 to change the optical path to the horizontal optical axis L2. In addition, a prism or mirror for changing the optical path to an optical axis L3 that hangs further downward is provided on the open optical axis 2, and the objective lens is provided below the optical axis L3. A condenser lens and a ring slit are arranged on the optical axis of the illumination optical system, and the reflected light from the eye to be examined is directed to the vicinity where a donut-shaped ring image is formed by the ring slit above the objective lens on the optical axis L3. A rod mirror for changing the optical path is disposed along the optical axis to the side from the optical axis L3, and an observation photographing optical system having a part of the finder and a photographing section is disposed on the optical axis L4 to the side. A fundus camera for bedside use, further comprising a two-sided prism disposed in a part of the finder.
