Title:
CONFOCAL LASER FUNDUS ANGIOGRAPHIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/040617
Kind Code:
A1
Abstract:
A confocal laser fundus angiographic device (100), comprises: an objective lens (10), a scanning lens (20), a scanning galvanometer (30), a mirror (40), a filtering module (50), an imaging detection assembly (60) and an excitation light source (70). The illumination light emitted by the excitation light source (70) enters the fundus passing through the scanning galvanometer (30), the scanning lens (20) and the objective lens (10). 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 (60) by passing through the objective lens (10), the scanning lens (20), the scanning galvanometer (30), the mirror (40) and the filtering module (50). The filtering module (50) comprises a base (51), a motor (52) mounted on the base (51), a rotary block (53) mounted on the motor (52) and at least one filter (54) mounted on the rotary block (53). The base (51) is provided with a light-through hole (513). The confocal laser fundus angiographic device (100) is capable of automatically switching the filter (54), thereby avoiding the problem of forgetting to switch the filter (54) due to the operator's mistake or switching the filter (54) by mistake.
