OPTICAL COLLIMATING SIGHT Russian patent published in 2009 - IPC F41G1/06 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to optical instrument making and can used in optical sights of sporting rifles, fowling pieces and combat firearms. The proposed sight incorporates a casing to house the device that displaces laying mark along with the light-diode radiator that shapes the said mark, laying mark brightness control device, power supply, optical collimating assembly, mirror and reflector representing a thin transparent plate. The collimating assembly comprises two optical lenses with their spherical surfaces tightly pressed against each other. The said surface of one of the said lenses features a multi-layer interference coat applied thereon to completely reflect the laying mark light beam from the radiator. The other surface features a semi-transparent multi-layer interference coat that reflects 50% of the laying mark light beam. The mirror and reflector are arranged at 45° to optical axis and horizontal plane located between the radiator and collimating assembly. The device that displaces laying mark consists of two slides. One of the latter accommodates a mirror arranged at 45° to the casing base.

EFFECT: higher accuracy of laying mark adjustment, simpler design.
