The AN/PVS-7 is a single tube biocular night vision device . Third-generation image intensifiers are able to be installed and are standard for military night vision. Most newer PVS-7 intensifier tubes are auto-gated to prevent image intensifier damage if exposed to intense light. The goggles have a built-in infrared Illuminator for low-light situations. They are waterproof and charged with nitrogen to prevent internal condensation while moving between extreme temperatures.
