Night sight special 1PN119
The Anti-Sniper special-purpose night vision sights are designed for detection of optical and optoelectronic sights (observation devices) by a splash of light from focally arranged elements of the optical system and for finding their range. As an illuminator, the use is made of an injection laser.
Developed by order of the Russian Ministry of Defense with a view of countersniping and controlling sensitive facilities.
— 1PN106 for the 7,62-mrn SVD and SVDS rifles;
— 1PN119 for the 7.62-mm PKMN and Pecheneg machine guns;
— 1PN120 for the 9-mm SVDK rifle;
— 1PN121 for the 12.7-mm ASVK rifle;
— 1PN123 for the SV-98 rifle.
— a quasi-continuous semiconductor pulsed laser emitter with the LFO modulation of emission pulses;
— a combination of a narrow-band interference filter with switched power supply of the optoelectronic image intensifier provides for operation in a wide range of light intensity from 1.5×104 to 1.5×10-4 Ix;
— provide for detection of camouflaged enemy;
— have no parallel.
