Fundus optical imaging system

The invention relates to a fundus optical imaging system, which sequentially comprises a front-end objective lens, a light filter, a rear-end relay lens and an image sensor, wherein an intermediate image plane is arranged between the front-end objective lens and the light filter; the front-end objective lens is used for obtaining an image of a fundus retina and imaging the fundus retina on the intermediate image plane; the light filter is used for filtering the image on the intermediate image plane into a monochrome image; and the rear-end relay lens is used for imaging the monochrome image on the image sensor. According to the fundus optical imaging system, the front-end objective lens, the rear-end relay lens and the image sensor are light path devices arranged according to the characteristics of the light filter, so that the light filter is fused into the whole light path, the additional space volume does not need to be increased and the volume of the fundus optical imaging system is reduced. 本发明涉及种眼底光学成像系
