Abstract
A fundus imaging device includes an objective optical system formed of a plurality of eccentrically disposed mirrors, and an SLO optical system and an OCT optical system which irradiate a fundus with light from a light source via the objective optical system and receive fundus reflected light. The fundus imaging device further includes a correction mirror as a part of the objective optical system, or between the objective optical system and the SLO optical system or the OCT optical system. The correction mirror corrects an eccentric aberration which occurs due to eccentric arrangement of the plurality of mirrors.
