Night Vision Quad Goggles YJFK
A new Ground Panoramic Night Vision Goggles, YJFK, has the purpose is to provide the operator more information under goggles, allowing him to move through the OODA Loop more quickly (Observe, Orient, Decide, Act). The most striking feature of the YJFK is the presence of four separate image intensifier tubes with four individual objective lenses arrayed in a panoramic orientation. The center two lenses points forward like traditional dual-tube goggles, giving the operator more depth perception. 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 outer tubes to produce an unprecedented 120 ° FOV, and 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 inter papillary adjustment options. They can also be easily removed and operated as independent hand-held viewers. The IPD of the two systems can be adjusted on the helmet mount.
The YJFK is powered by a battery on the device and remote battery packs, tethered to the unit via a standard DC cable. It comes with a package that accepts four 3-Volt CR123A batteries that 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.
