Patent ID: 8736935

Claim:
An optical deflection unit for scanning, ophthalmological measuring, and therapy systems comprising: a deflection mirror, movable through non-contacting electromagnetic drives in an oscillating fashion around at least one rotation axis, and the deflection mirror being arranged between at least two bearings in the direction of the at least one rotation axis, and the at least one rotation axis lying within a plane of the deflection mirror; a position sensor; and a control unit; the deflection mirror, the position sensor, and the control unit forming a control circuit for minimizing deviation of actual positions, detected by the position sensor, from the desired positions of the deflection mirror; wherein the deflection unit comprises a housing with a movable frame movable in an oscillating fashion around the at least one rotation axis, the frame holding the deflection mirror, and being secured in the housing via two bearings and the frame having permanent magnets, and wherein the deflection unit further includes, in the housing, non-contacting, electromagnetic drives in the form of electromagnets, which face the permanent magnets; and wherein the frame, which is movable in an oscillating fashion around a rotation axis in the housing, is further pivoted around an additional rotation axis, and wherein the two rotation axes lie orthogonally to one another.
