A system comprises a sensor subsystem for imaging an object space, and a telescope for coupling electromagnetic energy from the object space to the sensor subsystem. The system comprises a bypass optical path that bypasses the telescope on the way to the sensor subsystem in order to provide a larger field of view of the object space. The bypass path and the telescope path merge at a merging point between the telescope and the sensor subsystem, and are disjoint upstream of the merging point. A simple bypass configuration is therefore provided, with possibly just a single fold mirror at the merging point. A sensor may form an intermediate image, and a frame is placed at the intermediate image to reject stray radiation and provide a real and accessible intermediate pupil for the sensor. Other features are also provided.

The invention relates to a binocular observation device, in particular a field glass, with two visual optical paths and with a laser distance meter with a laser transmitter and a laser receiver and with an opto-electronic display element. A part of an optical path of the laser transmitter is integrated in a first visual optical path and a part of an optical path of the laser receiver is also integrated in the first visual optical path.

An apparatus is disclosed. The apparatus may include a housing detachably coupleable to an end of a sighting device. The housing may include a channel protruding from a side of the housing. The apparatus may include a one-way mirror disposed inside the housing. The one-way mirror may be positioned to allow an image from the sighting device to pass through the one-way mirror and reflect the image from the sighting device through the channel. The apparatus may include a mounting plate coupled to the housing. The mounting plate may include one or more adjustment bars that may be engageable with a visual recording device.

A direct view optical sight including an integrated laser rangefinder. One example of the sight includes an eyepiece, an objective providing an optical aperture and configured to direct electromagnetic radiation from a viewed scene to the eyepiece, an erector tube assembly coupled between the eyepiece and the objective, the laser rangefinder configured to transmit and receive laser radiation, and a beam combiner assembly mounted to the erector tube assembly and positioned between the erector tube assembly and the objective, the beam combiner assembly configured to combine the laser radiation and the electromagnetic radiation to allow the laser rangefinder to transmit and receive the laser radiation via the optical aperture of the objective, and to maintain optical alignment of the laser rangefinder and the viewed scene during movement of the erector tube assembly.

A binocular with an integrated rangefinder consisting of two tubes with observation channels, the optical systems of which include a Schmidt-Pechan prism reversion system with at least half-pentagonal prism and a Schmidt roof prism is provided. The laser transmitter of the transmitted infrared beam path is arranged in the first tube in parallel with the first observation channel towards the observed object and, furthermore, the display with an illuminated reticle and light beam is accommodated in the first tube, which, after passing through the integration display prism and the second separation layer on the reflective wall of the half-pentagonal prism and through the reversion system, is integrated into the first observation channel of the first tube.

A compact integrated optical system including an eyepiece, a reflective telescope, and a multi-spectral combiner optically coupled between the reflective telescope and the eyepiece, and configured to direct visible light received via the reflective telescope assembly along a direct view optical path to the eyepiece assembly. In one example, the multi-spectral combiner includes a display that displays a visual representation of the imagery of the viewed scene, and laser range-finder transceiver that transmits and receives a laser beam via the reflective telescope. A pair of beamsplitters is used to separate the imaging optical path from the direct view and laser range-finding optical paths. A blocking device is used to enable laser range-finding capability during daytime viewing of the imaging optical path imagery on the display. The reflective telescope provides a common aperture for the direct view optical path, an imaging optical path, and the laser range-finder transceiver.
