摘要： The technology generally relates to a binocular having two tubes, which are connected to one another by means of a hinged bridge pivotable about a hinge axis for adjusting the interpupillary distance. Within each of the two tubes a beam path is formed with a first optical axis of an objective lens, with a second optical axis of an eyepiece and with a prism erecting system, characterized in that the first optical axis of the objective lens and the second optical axis of the eyepiece are offset parallel to each other by a distance.

摘要： The present disclosure provides night vision binoculars with a replaceable objective lens. The night vision binoculars include: a main body, an objective lens and a locking member. The main body is provided with a mounting base; the objective lens is provided with a locking hole and detachably inserted into the mounting base. The objective lens rotates in the mounting base; and the locking member is slidingly disposed on the main body and provided with a locking position and an unlocking position. When the locking member is in the locking position, the locking member is inserted into the locking hole; and when the locking member is in the unlocking position. The objective lens can be removed from the mounting base. Through the above structure setting, the user is convenient to disassemble the objective lens; and the night vision binoculars are simple in structure and convenient to use.

摘要： An electromagnetic driving mechanism is provided for driving two different optical lenses, including a base, a first holder, a frame, a resilient element, a first electromagnetic driving assembly, a second holder, and a second electromagnetic driving assembly. The first and second holders are provided for holding the optical lenses. The frame is affixed to the base, has magnetically permeable material, and surrounds the first holder. The resilient element connects the first holder with the frame. The first electromagnetic driving assembly is disposed between the first holder and the frame to drive the first holder moving relative to the base. The second electromagnetic driving assembly is disposed on an outer side of the second holder to drive the second holder moving relative to the base.

摘要： An example head-mounted display device includes a light projector, an optical assembly arranged to direct light from a light projector to a user, and an actuator module. The optical assembly includes a variable focus lens assembly including a rigid refractive component, a shaper ring defining an aperture, and a flexible lens membrane between the shaper ring and the rigid refractive component and covering the aperture. The refractive component, the shaper ring, and the lens membrane are arranged along an axis. The refractive component and the lens membrane define a chamber containing a volume of fluid. The actuator module is configured to adjust an optical power of the variable focus lens by moving the shaper ring relative to the refractive component along the axis, such that a curvature of the lens membrane in the aperture is modified.

摘要： A non-lethal dazzling device includes a laser operable in the visible spectrum. The laser can be a relatively low-powered laser, such as a laser having a maximum output power of 2.5 mW, or it can be a higher-powered laser with a drive circuit that lowers the maximum output power to a safe level based on the range of the hostile target from the laser. In certain embodiments, the disclosed non-lethal dazzling device can be coupled to the bridge of a binocular device.

摘要： The invention relates to a binocular telescope comprising two tubes, which are connected in an articulate fashion with a swivel hinge pivotal around a joint bending axis. With a forehead contact unit comprising a comprehensive support device the binoculars can be supported in the area of the root of the nose or the forehead of the observer. The support device is here arranged at a body of the binoculars.

摘要： A focus tunable optical system includes a compound lens, which includes a plurality of focus tunable lenses. Further, the focus tunable optical system comprises a controller, which is configured to shift a focus of the compound lens from a first focal plane to a second focal plane. To this end, the controller is configured to apply, individually to each focus tunable lens of the plurality of the focus tunable lenses, a control signal having a first value for the first focal plane and a second value for the second focal plane.
