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. A passive movement damping device provides for a field image stabilization in the telescope. The monolithic spring joint has a spring arrangement 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 an unlatchable device. The passive damping device is configured as an eddy current device and includes a magnetic system about a stationary eddy current coil which has a nonlinear effect for the purpose of adjusting axially the damping constants. Isolated coils are disposed on the eddy current plate and can be short-circuited by means of a switch so that a specific, time-limited change of the damping constant is possible.
