OPTICAL BINOCULAR SIGHT (VERSIONS) Russian patent published in 2009 - IPC G02B23/18 F41G1/38 

FIELD: optics, weapons, ammunition.

SUBSTANCE: proposed sight comprises lens, reticule, two two-component relay systems, two lens rings and tree pairs of parallel-in-pair mirrors. The lens incorporates additional positive component arranged to move along the axis, ahead of the fist semi-transparent mirror. The second mirror is located parallel to the first one, reticule being arranged behind it at the lens focus. The first two-component relay system and third mirror, arranged perpendicular to the second mirror, are located on one axis with the said reticule. The fourth mirror arranged in parallel to the third mirror and first lens ring are located, further on, on aforesaid lens axis. Between the first and fourth mirrors on the said lens axis located are the following components, i.e. the fifth mirror arranged perpendicular to the first mirror, the second relay system with its axis perpendicular to the lens axis, and the sixth mirror arranged in parallel to the fifth one. The second lens ring is located on the axis parallel to the first lens ring and at identical distance, with the latter, from the lens. Interpupillary distance is varied by varying the gap between the second relay system components.

EFFECT: two-eyes observation, aiming and shooting.
