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

FIELD: physics.

SUBSTANCE: apparatus has a binocular sighting device consisting of two parallel viewing tubes, each having a lens, an erecting system and an eyeglass. One of the tubes has a net with an aiming mark. The emitter channel has a laser emitter with an optical system. The receiving channel has a photodetector with a receiving lens. The receiving lens is superimposed with the lens of one of the viewing tubes. Each viewing tube has two parallel slanted mirrors. In one of the tubes, the slanted mirror near the lens is a spectrum divider element. The second slanted mirror is displaced from the first mirror and reflects visible radiation towards the eyeglass. The erecting systems are in form of Pechan prism-erecting systems. The net is fitted in the viewing tube interfaced with the photodetector. The net, slanted mirrors and photodetector are in form of a monoblock. The eyeglass and slanted mirrors of the viewing tube without a net can turn about the optical axis of the lens of that tube.

EFFECT: smaller size of the laser range-finding binoculars with maximum light transmissio of its optical channels.
