The third generation low light level image intensifier is the core device of advanced low light level night vision system.

Its typical technical features are high sensitivity response gallium arsenide photocathode and high gain, low noise microchannel plate electron multiplier.

Its structural f eature is the use of double indium sealed proximity electron optical system. The third generation low light level image intensifier has important practical value in military and civilian applications such as observation, aiming, ranging, guidance, tracking and warning at night and other low illumination conditions.
