The first generation image intensifier module is electro-statically focused diode, incorporating S25 photocathde and P20 phosphor. Its magnification may be 1,greater than 1 or less than 1. Other types of photocathode and phosphor are available as requested, also available for output brightness uniformed and distortion corrected, flash protected and corona or static discharge protected.

First generation image intensifier assembly includes includes a module or staged modules with an integral high voltage power supply. It enjoys many special features, such as gain and maximum output brightness adjustable, automatic brightness control, flash protection, reverse polarity protection, lower input voltage and smaller input current. It is applicable in different environmental conditions conformed to environmental test requirement of military products, such as high temperature, lower temperature, vibration and shock, etc.
