ELF-FB20

ENHANCED NIGHT VISION BINOCULAR GOGGLES

The ELF-FB20 combines image intensifier technology with infrared thermal imaging in a binocular night vision system. Highlight and Outline fusion modes bring thermal information into the low-light view, while its compact, lightweight design supports comfortable use.

Calculated using the target detectability method defined by the Johnson criterion, with a human target measuring 1.7 m high × 0.5 m wide and a vehicle target measuring 2.3 m × 2.3 m. Calculations assume standard environmental conditions and the listed sensor specifications. Actual performance may vary with environmental factors, atmospheric conditions and operational settings.
