OPTICAL SIGHT FOR SMALL ARMS Russian patent published in 2004 - IPC

FIELD: optical instrument engineering. SUBSTANCE: the sight has a concave-convex telescopic lens, reticle, reticle lighting and a device for matching of the sight line with the weapon bore axis. The concave surface of the concave-convex lens is installed with the concavity to the pupil of the observer's eye, the concave surface or its central part is made semitransparent. The lens optical axis is parallel with the weapon bore axis. The reticle made in the form of a plane-parallel plate with a mirror sighting mark applied to its surface opposite the lens and a sighting marks made by etching, the vertices of both sighting marks coincide. The plane, onto which the sighting marks are applied, is located in the focal plane of the concave semitransparent surface of the lens. EFFECT: enhanced efficiency of the sight. 1 dwg
