Abstract
In an optical instrument such as a camera or a telescope, a first optical component is mounted to a housing and an inertially stabilized second optical component for compensation is mounted on gimbals. The gimbals are provided with an electric motor which has a rotor in the form of an annular magnet rotatably supported with the axis of rotation aligned with the optical axis of the optical instrument. The rotor serves as an inertial member to inertially stabilize the second optical component for compensation.
