Modernization of the armored vehicles night vision devices-TKN-3

Modernization of the armored vehicles night vision devices TKN-3 ( to TKN-3B, TKN-3UM and TKN-3BUM versions)
The improvement of the qualitative characteristics of the armored vehicles night vision devices due to their internal modernization (without changes of the external dimensions).
The result of modernization is the extension of the viewing field, division capacity and also enhancement of night vision device sensitivity that provides the device operation without illuminating on the much larger distances comparing to the pre-modernized facility.

PURPOSE
The improvement of the qualitative characteristics of night vision devices of the armored vehicles by means of their internal modernization (without changes to the external dimensions).
SPECIFICATIONS
  • The sensitivity of the modernized night vision device (basic characteristic) – 0.25 microlux (a million times better that the existing night vision devices of the armored vehicles, which have sensitivity of 0.2 lux)
  • It is possible to use it day and night
  • Resistance to the flashes of the light flux (not dazzled with the gun shots)
  • Adjusting the brightness gain (automatic and manual)
  • The unique technological solution for the image-converter tube and optics (glass with an antireflective coating, which is resistant to the radiation)
  • Power supply - 7-50 V
  • No need in illumination
