Abstract
Abstract The invention relates to a binocular telescope having cardanically journalled inverting systems mounted on a symmetrical double holder. This double holder is connected via a spring joint to a stationary non-movable base frame which is mounted at the pivot point of both inverting systems. An active movement damping device provides for a field image stabilization in the telescope. The monolithic spring joint provides a spring action perpendicular to the optical axis with the springs being thickened in the axial direction toward the edge to improve supporting capability. Shock protection is provided in the region of the support pivot point and contains a releasable latching device. The active damping device consists of a magnet system movable relative to a current coil fixed to the housing. This current coil exhibits a nonlinear effect in order to axially adjust the damping constant. A magnet field sensor is located in the current coil and controls the current flow through the coils via a circuit so that a specific, time-limited change of the damping constant is possible.
