Ophthalmic imaging device for imaging posterior and anterior eye regions

An ophthalmic imaging device for imaging a posterior and an anterior region of an eye, the device comprising:

• a fundus module comprising:
• an illumination module adapted to yield a first partially blocked beam along an illumination axis;
• and
• an imaging module aligned along an imaging axis, wherein the imaging axis is perpendicular to the illumination axis, the imaging module comprising:
• a mirror with a hole, the mirror being placed at an angle to the illumination axis, wherein the first partially blocked beam is incident on a first side of the mirror to produce a reflected first partially blocked beam and a second partially blocked beam along the imaging axis;
• at least one objective lens adapted to focus the reflected first partially blocked beam and the second partially blocked beam received from the first side of the mirror, to produce a cornea illuminating doughnut and a pupil illuminating doughnut, respectively, on the cornea and pupil of the eye, and form an image of the posterior region of the eye on an image plane;
• and
• a diopter correcting lens placed at a distance from a second side of the mirror along the imaging axis for adjusting a viewing focus of the image of the posterior region of the eye;
• and
• a slit lamp module adapted to view and capture the image of the posterior region of the eye through the diopter correcting lens, wherein the slit lamp module and the fundus module are movably coupled to each other, and wherein the diopter correcting lens is adapted to adjust the viewing focus to compensate for one or more of a shift in the image plane, change in the focus upon a linear movement of the slit lamp module, and a viewing module.
