SIGHT Russian patent published in 2009 - IPC G02B23/10 F41G1/38 

FIELD: physics, optics.

SUBSTANCE: sight comprises the following components along with direction of rays - objective, collective lens, turning system, the first mesh containing nontransparent dashes on transparent background and installed in ocular focus, ocular and the second mesh. Additionally beam-splitter cube is introduced, which is installed between the first mesh and ocular, beam splitter plane of which is inverted to the first mesh with its first end, and with its second end - to ocular, and three light diodes installed above the second mesh. The second mesh containing transparent dashes on nontransparent background is installed parallel to sight axis and cathetus facet of cube, which produced cube rib together with the first end of beam-splitter plane. Collective lens is installed in front of focal plane of objective.

EFFECT: creation of telescopic sight with properties of collimator sight.
