Long-range optical device having image stabilization

A long-range optical device, comprising

• at least one optical channel having a housing and an arrangement of optical elements,
• at least one of the optical elements being movable relative to the housing for image stabilization in the event of perturbing movements of the housing,
• a first passive stabilization system based on mass inertia and acting on the at least one movable optical element, the first passive stabilization system being configured to generate a first restoring force proportional to the displacement amplitude and a second restoring force proportional to the displacement velocity in the event of displacement of the at least one optical element relative to the housing,
• the first stabilization system being configured for image stabilization in the event of perturbing movements in a first frequency range,
• at least one second stabilization system acting on the at least one movable optical element, the at least one second stabilization system coupled to the first stabilization system and configured for image stabilization against perturbing movements in at least one second frequency range,
• the first and the at least one second frequency ranges being at least partially different.
