Abstract: A long-range optical device has at least one optical channel which comprises a housing and an arrangement of optical elements. At least one of the optical elements is movable relative to the housing for image stabilization in the event of perturbing movements of the housing. The device further comprises a stabilization system for the at least one movable optical element, which has an eddy current damper for damping movements of the at least one movable element. The stabilization system, in the event of a displacement of the at least one movable optical element, generates a restoring force proportional to the displacement velocity of the at least one movable optical element. The eddy current damper comprises a magnet system and an eddy current carrier interacting therewith. The restoring force generated by the eddy current damper is dependent on the amplitude of the displacement of the at least one movable optical element.

This holding arrangement is usable with many cameras and binoculars or monoculars.

Abstract: A method and apparatus for stabilizing glow plasma discharges by suppressing the transition from glow-to-arc includes a perforated dielectric plate having an upper surface and a lower surface and a plurality of holes extending therethrough. The perforated dielectric plate is positioned over the cathode. Each of the holes acts as a separate active current limiting micro-channel that prevents the overall current density from increasing above the threshold for the glow-to-arc transition. This allows for a stable glow discharge to be maintained for a wide range of operating pressures (up to atmospheric pressures) and in a wide range of electric fields include DC and RF fields of varying strength.

Abstract: The invention is directed to a mirror for changing the geometric shape of a light beam. A two-dimensional intensity distribution substantially independent of the mode structure can be generated by mounting a grating in the optical beam path of the laser beam. The intensity distribution is constant in one direction and, in a direction perpendicular thereto, the intensity can have any preselectable intensity distribution.
