Abstract
The disclosure provides an optical component for retinal imaging including: a light source module, a beam splitter, an imaging module, a scanning module, and a flat field objective lens. The flat field objective lens is between the scanning module and a detection position, the light source module is configured to emit, to the beam splitter, a detection light for illuminating a fundus, the detection light being guided by the beam splitter to the scanning module and emitted to the detection position through the scanning module and the flat field objective lens, reflected light from the detection position can pass through the scanning module and reaches the beam splitter, and is guided by the beam splitter to the imaging module. The scanning module includes a scanning objective lens reciprocally movable along its central axis, and the flat field objective lens is reciprocally movable along its central axis.
