  • Publication number: 20080030679
    Abstract: An ophthalmic camera (10) comprising a camera (12) having a lens (18) aligned with a second lens (16) and at least one illumination means (14). The illumination means (14) is capable of movement relative to the camera lens (18) so that the beam of light emitted by the illumination means (14) is able to be focused by the second lens (16) through the pupil onto the fundus. In another embodiment, the ophthalmic camera comprises a camera (52), an illumination means (54) and a beamsplitter (58). The camera (52) and the beamsplitter (58) from an alignment axis X and the illumination means (54) together with the beam splitter (58) form an illumination axis Y perpendicular to the alignment axis X.
