Night observation instrument NNP-21
Russian designation: ННП-21 (ночной наблюдательный прибор)
Manufacturer: Karl Zeiss Jena
Designation:
The NNP-21 is a monocular periscopic observation instrument designed for night observation of the battlefield, reconnaissance of detected targets and for fire repair in conditions of natural night illumination without illumination.
With average illumination (0.003 - 0.005 lux) and good atmospheric clarity, the target (tank, OT, BVP) can be seen up to 1000 m away.
The instrument allows measuring the directional angle (azimuth) and position angle of the target and determining its distance.
Basic TTD:
- magnification .......... 6.3x
- field of view .......... 6°
- periscopicity .......... 385 mm
- target velocity approximately 4 km/h .......... from the screen
- value of 1 part of the targeting warp of the focal plate .......... 0 - 05 dc
- persons individually or in a group .......... 3 - 4 km
- power supply - 2NKBN power supply ..........2.5 V
- power supply - vehicle on-board power supply .......... 13/26 V, DC
- observation range at night .......... 1000 m
- weight of the instrument with power supply .......... 15000 g
Composition and purpose of the kit in BPzV (composition differs from the portable version):
- Instrument NNP-21 with internal parts:
o head section with lens
o lens hood assembly
o lens light filter assembly
o mirror
o eyepiece
o electro-optical image converter
o buzzer
o spirit level assembly
o eyepiece
- stand - tripod is designed to position the instrument outside the vehicle and to position it, It can also be used to align the P-01 radar block of the PSNR-5
- limbus mount is designed to align the instrument on the left universal mount on the vehicle tower
- vehicle mount is designed to align the instrument on the vehicle, usually on the left universal bracket on the turret
- storage/transport chest with accessories (located behind the commander's seat) is designed for storing and transporting the instrument, storage and storage of its complete accessories, except for the tripod stand and the limbus fixture (located next to the Ranger-Operator and Ranger-Navigator seats)
The attached pictures show and describe the location of the items in the transport case, a general view of the equipment and controls of the NNP-21.
