The L3Harris Binocular Night Vision Device, also known by the military nomenclature AN/PVS-31A, is a compact, lightweight, Generation III high-performance white phosphor dual-tube goggle. The PVS-31 is capable of utilizing an on-board AA or remote cold weather battery pack. Being that the system is so lightweight, the battery pack is sufficient counterweight for long term use comfort. Device weight comes in at just under 1 pound ; one of the lightest units on the market. The PVS-31A features manual gain control, individually articulating optical pods, inter-pupillary distance stops, and 2376 minimum FOM Unfilmed White Phosphor intensifiers. Within the spec parameters of the intensifier tubes used in the PVS-31A, the signal to noise ratio must be a minimum of 33 and resolution 72lp/mm. Furthermore, the halo value must not exceed .85. Together all of this means a truly exceptional image quality and absolute top tier performance.
This device is serviceable by L3Harris outside of warranty term.
