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.

Claim (Index 1):
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, said excitation light source emits illumination light passing through said scanning galvanometer, said scanning lens, said objective lens, and then entering in the fundus, the fluorescent substances in the fundus vein are excited by the illumination light to emit light with a specific wavelength, said light with the specific wavelength passes through said objective lens, said scanning lens, said scanning galvanometer, said mirror, said filtering module, and then enters in said imaging detection assembly, wherein said filtering module comprising a base, a motor mounted on said base, a rotary block mounted on said motor, and at least one piece of filter mounted on said rotary block, said base is provided with a light-through hole, said rotary block is a fan-shaped piece, said fan-shaped piece comprising a circular arc end and a top end, said top end opposite to said circular arc end and it is provided with a mounting hole, said rotary block is mounted on said motor through said mounting hole, a blocking block is formed on outer side of said circular arc end facing away from said top end, a pair of limiting blocks are disposed on said base, said blocking block cooperates with said limiting blocks to limit a rotation angle of said rotary block, when said confocal laser fundus angiographic device in operation, said rotary block rotating under the driving of said motor to achieve that said filter and said light-through hole coincide.
