  • Patent number: 11986243
    Abstract: Disclosed is a fundus camera, which relates to the technical field of medical devices and includes: an illumination module, a main optical assembly, a focusing module, and an image sensing acquisition module; the illumination module includes a plurality of light sources configured to emit light of different wavelengths, illumination light emitted by the plurality of light sources is conducted to enter an eye of a patient through the main optical assembly, and light reflected by a retina of the patient is conducted to pass through the main optical assembly and the focusing module to enter the image sensing acquisition module. The fundus camera provided by the present application improves the technical problem that the fundus camera in the prior art cannot image different layers of the retina, thereby providing valuable medical and diagnostic data.

  • Publication number: 20200329962
    Abstract: Retina digital imaging system, instrument and method A retina digital imaging system includes: an illumination module (1), a main optical assembly (3), and an image sensor module (2); the illumination module (1) includes light-emitting diodes capable of emitting light with different wavelengths, and each light-emitting diode emits light to enter the retina through the main optical assembly (3) to form an illumination optical path; the light reflected by the retina passes through the main optical assembly (3) and forms an image on the image sensor module (2) to form an imaging optical path. The various spectral bands formed by light-emitting diodes may form a wider spectrum, so different layers of the retina may be imaged to provide valuable medical and diagnostic data.
