Abstract: An optical observation instrument has a device (1) for protecting against incoming flare (40) arranged within the beam path of the instrument. The device contains a filter (22/30) tuned to the flare (40). The filter (22/30) is configured and arranged within the beam path such that the flare (40) transits the filter (22/30) at least two times.

Abstract: A telescope has at least one barrel. At least three optical elements, namely an objective lens, an inverting system, and an eyepiece are arranged within the barrel along a longitudinal axis thereof one behind another. Further, shaking movements of the barrel are compensated for by moving at least one of the optical elements relative to the barrel. The objective lens is rigidly connected to the barrel. The inverting system together with the eyepiece constitutes a common assembly. At least a part of the assembly is adapted to be moved relative to the longitudinal axis. As an alternative, the inverting system and the eyepiece are rigidly connected to the barrel and at least a part of the objective lens is adapted to be moved relative to the longitudinal axis.

Abstract: A holding device holds a camera rearward of an ocular of a glass such as a monocular or binocular to record an image utilizing the camera. The image is made available by the glass. This holding arrangement is usable with many cameras and binoculars or monoculars. A rapid change between the camera positioned forward of the ocular and a cleared ocular is made possible for the direct viewing by the user through the glass (binocular or monocular).

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 sighting telescope has an inner tube that moves transversely of the telescope axis relative to an outer tube, and operating elements arranged mutually at an angle for transversely displacing the inner tube. In an embodiment of the invention, the outer tube has an enlarged internal diameter in the region of the operating elements. In a second embodiment of the invention, a leaf spring is arranged for producing a restoring force on the inner tube, extends in a substantially radial direction, and has radially offset support places, both on the outer tube and on the inner tube. The leaf spring is preferably arranged in the neighborhood of the enlarged internal diameter.

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: The telescopic system with imaging function comprises at least one tube having a beam path through an objective and an eyepiece. Furthermore, the telescopic system has a device for coupling out a partial light beam. A module with an image sensor for converting images into digital data is fitted to a housing of the tube which contains the device for coupling out the partial light beam in such a way that it is possible to couple out an optical signal on the image sensor. A completely autonomous digital camera with an interface for an additional external image sensor is likewise present.

Abstract: The invention is directed to a housing for a binocular (1) having a hard base body (9) which is encased in a soft outer skin (21). The outer skin (21) is attached with the aid of a latch mechanism.

Abstract: A telescopic sight with variable magnification includes an adjusting ring for varying the magnification. The telescopic sight housing and an eyepiece stub are arranged together in a single part. The adjusting ring is arranged between the eyepiece and an object in a groove formed between the telescopic sight housing and the eyepiece stub.

Abstract: A carryable optical magnifying device can be worn during use by the user, and relates in particular to binoculars or field-glasses with a carrying strap attached to the housing of the magnifying device. The carrying strap is passed outward laterally of the eyepiece region of the magnifying device through an opening in the outer portion of the housing. The opening has substantially the same cross section as the carrying strap. The carrying strap has at its end within the housing a thickening that is larger than the opening for the carrying strap in the outer portion of the housing. An inner cavity into which the thickening is inserted, is formed within the housing with the cooperation of a clamp member.

Abstract: The invention is directed to a pancratic system in an optical apparatus having a guide tube wherein at least one lens is moved in the guide tube. At least two guide rails are provided between the lens and the guide tube for guiding the lens. The surfaces of the intermediate spaces between the guide rails are configured so as to be poorly reflective and the space between the guide rails is also configured so as to be poorly reflecting.
