AGM 11769 Generation 2+ Advanced Performance image intensifier tubes (IIT) are designed in a compact 37mm format with manual variable gain control. AGM IITs feature a high-sensitivity S-25 multialkali photocathode evaporated onto a glass input window, a microchannel plate with either a P-43 green or P-45 white phosphor display on an inverting fiber-optic window. AGM 11769 GEN 2+ Advanced Performance IITs offer high signal-to-noise ratios and high resolution to provide the user with extended range detection along with excellent subject identification under low ambient lighting conditions. This is combined with a small halo, output of spherical positive, and 10,000-hour lifespan.
