Featuring lightweight design with independently pivoting optical tubes, the ATN PS31-2 Binocular Night Vision Device provides users with the resolution, situational awareness, and ergonomics needed for effective nighttime operation. The Gen 2 P43 green phosphor light intensifier tubes deliver 58-60 lp/mm resolution for a clear view, while the 1x magnification, 1.18mm lenses offer a 40° field of view and can focus as close as 9" away. An infrared illuminator supplements the intensifier tubes in total darkness, with an in-view indicator light letting you know it's on. The PS31 runs approximately 60 hours on one CR123A battery and comes with a helmet mount.
