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.
It is used by the United States army, and is known for its low cost and wide range of uses and modification ability. Some higher end devices including the PVS-31 binocular and GPNVG-18 quad-tube night vision are used by special forces groups, but are costly. Monoculars are generally preferred by developed forces.
The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) is a third-generation passive monocular night vision device developed for the United States Armed Forces by ITT Exelis.It fuses image-intensifying and thermal-imaging technologies, enabling vision in conditions with very little light.
Manufacturing facilities were dispersed along the 2-mile (3.2 km) power canal to minimize damage during infrequent explosions.
