摘要:
A fundus imaging apparatus includes an imaging optical system that irradiates a fundus of a subject eye with light through an objective lens system, and enables to capture a fundus image of the subject eye based on return light from the subject eye, and a diopter correction unit that includes an optical element disposed on an optical path of the imaging optical system and a drive unit driving the optical element, and performs a diopter correction with a diopter value corresponding to a drive amount of the optical element. A drive range of the optical element in the diopter correction unit is set to avoid a specific range being a range in which an artifact caused by reflection light in the objective lens system is maximized.
