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. ^ 3 dwg |
