Function: Image intensifying, passive binoculars which allow the operator to perform tasks at night or under low light level conditions.





Description: The AN/PVS-7B is a single-tube night vision goggle, Generation III image intensifier which uses prisms and lenses to provide the user with simulated binocular vision. The Marine Corps is acquiring the AN/PVS-7B, a model which incorporates a high light level protection circuit in a passive, self-contained image intensifier device which amplifies existing ambient light to provide the operator a means of conducting night operations. A shipping case, soft carrying case, eyepiece and objective lens cap, and filter are ancillary items. A demist shield is also provided to prevent fogging of eyepiece.





Background: The AN/PVS-7B represents the current state of the art in night vision goggles. Initially, it will augment the AN/PVS-5 NVG, and over time, it will replace the AN/PVS-5. The Marine Corps is interested in procuring a clip-on Night Vision Magnification Device (NVMD) to satisfy the need to see targets at the maximum effective range of its weapons.
