Abstract: A long-range optical apparatus, particularly a binocular having two tubes for accommodating long-range optical devices, includes a first folding bridge, a second folding bridge, and preferably a third folding bridge. The folding bridges are pivotably arranged between the tubes of the long-range optical device and each include a first and a second bridge element associated with each other and pivotable relative to each other. At least one folding bridge has a fit that prevents mechanical contact of the bridge elements to each other at least in regions of the pivoting range of the bridge elements.

Abstract: An adjusting device for linearly displacing an assembly has a rotary knob rotatable in first and second rotary directions. A gear unit rapidly displaces the assembly in a first linear direction when the rotary knob is rotated in the first rotary direction and slowly displaces the assembly in a second linear direction opposite the first linear direction when the rotary knob is rotated in the second rotary direction over a defined rotation angle.

Abstract: A focusing optic can be axially displaced along the optical axis in a housing with the aid of coarse and fine drives. The coarse drive includes a coarse belt drive by which the coarse drive and the focusing optic cooperate actively with one another and the fine belt drive is provided for connecting the fine drive and the focusing optic.

Abstract: A latch mechanism for producing a releasable connection of a housing portion with a further housing portion provides projections on one of the housing portions, and for producing a releasable connection by means of a rotational motion of the housing portions relative to one another, the latch projections latchingly engaging in associated latch recesses, where the latching mechanism includes a rotatably mounted ring element including the recesses for receiving the projections. The latching mechanism can be connected by means of further latch recesses and further latch projections to the further housing portion.

Abstract: A pair of binoculars includes a rotating element. When the rotating element is actuated, the lens of the binoculars, which are used for focusing, are displaced. The lenses are mounted in an axially displaceable manner. A rotating movement initiated by the rotating element is translated into a rotating movement with a larger angle of rotation by means of a gear transmission stage.

Abstract: A telescope has an optical axis established by the optical elements of the telescope and at least one lens mounted displaceably along the optical axis. A motorized drive is provided for driving the at least one displaceably mounted lens.
