An instrument for measuring the optical properties of the eye in the entire field of vision, including refraction and aberrations, which comprises a frame (1) mounted on an ophthalmologic table (2) that can be oriented in three perpendicular directions X, Y, Z, having a support surface (19) for the head of the subject, a hot mirror (3) and a long mirror (4) united to frame (1) in front of the head. It also comprises an illumination sub-assembly (5) consisting of a fibre optic head (6); a lens (7) (L1), a diaphragm (8) (D), a beam splitter (9) (BS), and a measurement sub-assembly (10) with two lens (11) L2 and (12) L3, two mirrors M1 (13) and M2 (14); a camera (15) with a matrix (16) of micro-lenses on the inlet of camera (15), in such a way that said camera (15) is placed on the focal plane of the micro-lenses; Frame (1) has a motor (17) mounted on it, the shaft of which rotates in the Y direction, to which an arm (18) is attached that can rotate on said shaft; being mounted on said arm (18) the components of illumination sub-assembly (5), the components of measurement sub-assembly (10) and camera (15) with matrix (16) of micro-lenses. |
