Abstract (en)
[origin: WO2013104593A1] The invention relates to a long-range optical device (10) having at least one optical channel (12) which has a housing (14) and an assembly of optical elements (16, 18, 20), wherein at least one of the optical elements (16, 18, 20) is movable relative to the housing (14) for image stabilization during disturbing movements of the housing (14), and a first passive, inertia-based stabilization system (26) for the at least one movable optical element (18) which generates a first restoring force upon excursion of the at least one optical element (18) relative to the housing (14), proportionally to the excursion, and generates a second restoring force, proportionally to the excursion velocity, the first stabilization system (26) being designed for image stabilization during disturbing movements in a first frequency range. The long-range optical device (10) has at least one second stabilization system (28) which is coupled to the first stabilization system (26) and is designed for image stabilization against disturbing movements in at least one second frequency range, wherein the first and the at least one second frequency range are at least partially different.
