TELESCOPIC SIGHT Russian patent published in 2014 - IPC G02B23/10 F41G1/38 

FIELD: physics.

SUBSTANCE: telescopic sight includes a common eyepiece and two parallel-arranged optical channels with different magnification, each having on the beam path a lens, a grid and an erecting system. The common eyepiece is placed on the axis of the channel with lower magnification. Lenses of both channels have the same focal distance, in the common focal plane of which the grids are placed. The channel with higher magnification is further provided with an optical element which is placed in front of the focal plane and is configured to shift the axis of the optical channel with higher magnification.

EFFECT: simple design while maintaining functional capabilities, high reliability and low cost of the telescopic sight.
