Fundus photography device

A fundus photography device comprising:

• a fundus illumination optical system including at least a photography light source and an observation light source, the fundus illumination optical system configured to illuminate a fundus of a subject's eye;
• a fundus photography optical system including at least a first imaging sensor configured to photograph the fundus, and a second imaging sensor configured to observe the fundus, the fundus photography optical system configured to photograph a front image of the fundus;
• an OCT optical system including at least a measuring light path, a reference light path, and a photodetector configured to detect an interference signal between light from the measuring light path and light from the reference path, and configured to obtain a tomographic image of the fundus using optical coherence tomography;
• an objective lens configured to be disposed in front of the subject's eye;
• a hole mirror;
• an anterior eye observation optical system configured to observe an anterior eye of the subject's eye;
• a first wavelength selective splitter disposed between the objective lens and the hole mirror, and configured to set a first optical axis commonly shared by the fundus illumination optical system and the fundus photography optical system to be coaxial with a second optical axis commonly shared by the OCT optical system and the anterior eye observation optical system;
• and
• a second wavelength selective splitter disposed upstream of the second wavelength selective splitter, and configured to set an optical axis of the OCT optical system to be coaxial with an optical axis of the anterior chamber observation optical system to form the second optical axis.
