Abstract:
A confocal laser fundus angiographic device, comprises: an objective lens, a scanning lens, a scanning galvanometer, a mirror, a filtering module, an imaging detection assembly and an excitation light source. The illumination light emitted by the excitation light source enters the fundus passing through the scanning galvanometer, the scanning lens and the objective lens. Fluorescent substances in fundus vessels are excited by the illumination light and emit light with a specific wavelength. The light with a specific wavelength enters the imaging detection assembly by passing through the objective lens, the scanning lens, the scanning galvanometer, the mirror and the filtering module. The filtering module comprises a base, a motor mounted on the base, a rotary block mounted on the motor and at least one filter mounted on the rotary block. The base is provided with a light-through hole. Compared with the prior art, the confocal laser fundus angiographic device is capable of automatically switching the filter, thereby avoiding the problem of forgetting to switch the filter due to the operator's mistake or switching the filter by mistake.
