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

FIELD: physics, optics.

SUBSTANCE: sight comprises the following serially installed components: objective, mesh, two-component turning system and ocular. Additionally beam-splitter cube, three mirrors and positive components are introduced. Beam-splitter cube is installed between components of turning system, its beam-splitter plane is arranged in the form of diagonal facet, lower part of which is located closer to objective. On top above the cube there is an additional positive component glued of two lenses, above which the following components are installed: the first flat mirror parallel to beam-splitter cube facet, then the second flat mirror installed perpendicularly to the first mirror in front of focal plane of ocular, and the third mirror inclined to optical axis and inverted with their reflecting surface to ocular and installed between focal plane of ocular and the second component of turning system.

EFFECT: possibility to observe large visual field with low magnification and central part of visual field - with high magnification due to provision of low and high magnifications simultaneously and jointly.
