COLLIMATING SIGHT Russian patent published in 1997 - IPC

FIELD: open-type collimating sights for small arms and sporting guns, as well as for close combat weapon. SUBSTANCE: sighting device has a case containing two parallel tubes, one of which accommodates the target observation and sighting mark channel, and the other - the collimator sighting mark formation channel. The collimator sighting mark formation channel has luminescent rod 1 placed in a transparent cap, diaphragm 4, combined with which is the outlet end of rod 1, collimator lens 7. Collimator lens 7 and diaphragm 4 positioned in its focal plane are placed in frame 9 spring-loaded by means of cylindrical spring 5, frame 9 is made as a ball-and-socket joint. The target observation and sighting mark channel uses semitransparent mirror 12 that may have a coating that reflects light with a wavelength corresponding to radiation of luminescent rod 1, and neutral light filter 10 installed on the channel outlet window so as provide a more contrast image of the sighting mark on the target. EFFECT: enhanced reliability in heavy operating conditions, enhanced precision of adjustment of the optical system and enhanced contrast range of sighting mark and target, which essentially enhances the sight efficiency. 2 cl, 1 dwg
