- 摘要：
PROBLEM TO BE SOLVED: To provide an ophthalmic photographing device, where the entrance of noise light into a light reception device is controlled so that a better photograph image may be available.
SOLUTION: The ophthalmic photographing device to take the photograph of a subject eye includes a separation part placed at a common light path of an irradiation optical system and a photographing optical system, and having two concentric different regions in order to separate laser light from reflective light. As for the two different regions, in respect to the laser light emitted from a light source and the reflective light directed to the light reception device from the subject eye, there are a light separation part that has a first region to pass some light fluxes and a second region to reflect the other light fluxes. The photographing device further includes a shielding part, provided between the second region and the light reception device, that has a light shielding region to shield the central part of reflective light by the separation part and a light passing region that passes the peripheral part of reflective light.
