  • Patent number: 11998277
    Abstract: An ophthalmic imaging device (300) includes a fundus module (210) and a slit lamp 5 module (220) movably coupled to each other. The fundus module (210) includes an illumination module (230) and an imaging module (240). The illumination module (230) is adapted to yield a first partially blocked beam. The imaging module (240) includes a mirror (324) with a hole and an objective lens (326) to produce a reflected first partially blocked beam and a second partially blocked beam, to form a cornea 10 illuminating doughnut (502) and pupil illuminating doughnut (504), respectively, on an anterior region of the eye and form an image of the posterior\\region of the eye on an image plane (346). The slit lamp module (220) is adapted to view and capture the image of anterior and posterior regions of the eye.

  • Patent number: 11219365
    Abstract: The present subject matter relates to an ophthalmologic imaging apparatus, which can capture reflex-free retinal images of a subject's eye. The imaging apparatus comprises light sources arranged on an illumination axis. A first shield placed at a distance from a first condenser lens, which is placed in front of a photographic light source on the illumination axis. The first shield has a central opaque portion on which an observation light source is mounted, and an outer pair of coaxial annular transparent regions. A diffuser is placed in front of the observation light source. A second shield has a central opening portion and mounted on the diffuser. The imaging apparatus further comprises a porosity mirror mounted on a porosity tube.

  • Patent number: 9398851
    Abstract: A retinal imaging device and illumination module. The illumination module includes a light source to provide an incident beam along an illumination axis, a condenser lens at a spaced apart distance from the light source for condensing the incident beam and emanating a condensed incident beam, a transparent plate at a spaced apart distance from the condenser lens, wherein the transparent plate comprises a light absorber, at least one projections lens system to focus the condensed incident beam, a shield at a spaced apart distance from the projection lens system to yield a first partially blocked beam to form a comea illumination doughnut, and a perforated mirror comprising a hollow cylinder. A portion of the hollow cylinder protrudes out from a reflecting face of the mirror, forming an elliptical stopper to yield a second partially blocked beam to form a pupil illumination doughnut, enabling reflex-free imaging of the retina.
