Night Vision Quad Goggles EFG-18N

Description

With the new technology, developed a new Ground Panoramic Night Vision Goggles which called EFG-18N, The purpose of the EFG-18N is to provide the operator more information under goggles, allowing him to more quickly move through the OODA Loop (Observe, Orient, Decide, Act).

The most striking feature of the EFG-18N is the presence of four separate image intensifier tubes with four separate objective lenses arrayed in a panoramic orientation. The center two lenses point forward like traditional dual-tube goggles, giving the operator more depth perception, while two more tubes point slightly outward from the center to increase peripheral view.

The two tubes on the right and the two on the left are spliced at the eyepieces. The operator sees the two center tubes somewhat overlapping the two outer tubes to produce an unprecedented 120° FOV. This is an absolute game-changer for the SOF community.

The two right and two left tubes are housed in merged assemblies and are hung from a bridge, giving operators interpupillary adjustment options. They can also be easily removed and operated as independent handheld viewers. The IPD of the two system can be adjusted on the helmet mount.

The EFG-18N is not only powered by a battery on the device, but also by a remote battery packs, tethered to the unit via a standard DC cable. It comes with a pack that accepts four 3-Volt CR123A batteries that tend to power the unit for 50-80 hours (IR off). The remote battery pack provides a secondary function as a counterweight, which is needed considering the goggle weighs about 880g..
