LASER RANGEFINDER BINOCULARS Russian patent published in 2012 - IPC G01C3/08 G02B23/02 

FIELD: optics.

SUBSTANCE: device contains a binocular telescope sight comprising two parallel anallactic telescopes, each of them capable of switching on an object lens, an inversion optical system and a view lens. One of the sight tubes comprises a grid with a telescope laying mark. A handpiece channel comprises a laser emitter with an optical system. A receiving channel comprises a photodetector with a receiving lens, wherein the receiving lens is superimposed with the lens of one of the anallactic telescopes. A display resolver is connected to the laser emitter and the receiving channel outputs. Each of the anallactic telescopes house two parallel inclined mirrors. The first inclined mirror located closer to the lens in one of the telescopes is a spectrum- dividing element. A sensitive photodetector area is conjugated with the telescope laying mark. The second anallactic telescope houses a second photodetector, its first inclined mirror being a spectrum- dividing element. The output of the second photodetector is connected to the resolver.

EFFECT: enhanced obtained range without the increase of the rangefinder binoculars dimensions.
