Abstract
A long-range optical device has at least one optical channel which comprises a housing and an arrangement of optical elements. At least one of the optical elements is movable relative to the housing for image stabilization in the event of perturbing movements of the housing. The device further comprises a stabilization system for the at least one movable optical element, which has an eddy current damper for damping movements of the at least one movable element. The stabilization system, in the event of a displacement of the at least one movable optical element, generates a restoring force proportional to the displacement velocity of the at least one movable optical element. The eddy current damper comprises a magnet system and an eddy current carrier interacting therewith. The restoring force generated by the eddy current damper is dependent on the amplitude of the displacement of the at least one movable optical element.
