A fundus imaging device 100 includes a scanning optical system 1 that includes optical scanners 15 and 27 which change the travelling direction of light from light sources 11 and 21 so as to scan a fundus Er with the light; and an objective optical system 2 that is disposed between the optical scanners 15 and 27 and a subject's eye E, and guides light from the optical scanners 15 and 27 to the fundus Er. The fundus imaging device 100 forms an image of the fundus Er based on fundus reflected light. The objective optical system 2 includes a first mirror 50 that reflects light from the optical scanners 15 and 27, and thus forms a first pivot point r1 around which light turns in correspondence with the operation of the optical scanners 15 and 27, and a second mirror 60 that further reflects light reflected by the first mirror 50, and thus forms a second pivot point r2 around which light emitted to the subject's eye E turns. The swing angle of light incident to the first mirror 50 is smaller compared to the swing angle of light with respect to the second pivot point r2. |
