Ground Panoramic Night Vision Goggles YJ4K
Product Description
Night vision goggles are electronic devices that allow the wearer to see better in the dark. They offer a hands-free alternative to other night vision equipment. While consumer-grade products are available, night vision goggles are often used in military or law enforcement settings.
YJ4K Panoramic Night Vision Panoramic Night Vision (YJ4K) with ground panoramic night vision observation capability. The purpose of YJ4K is to provide more information to the user in the night vision environment, enabling him to go through the OODA loop (Observe, Orient, Decide, Act) faster. The most notable feature of YJ4K is that there are four independent image intensifier tubes, and four independent objective lenses are arranged in a panoramic direction. The middle two lenses point forward like traditional binocular night vision, giving the user more depth perception, while the other two point slightly outward from the center to increase peripheral vision. The two tubes on the right and the two tubes on the left perform image stitching and fusion at the eyepiece. The user sees the two central images overlapping the two outer images, resulting in an unprecedented 120° field of view. This is an absolute game changer for night vision gear. Two imaging systems on the left and right are installed side by side on the support frame and suspended on a hanger similar to the ANVIS night vision helmet, providing users with complete adjustment options. They also easily detach from the stand as a standalone handheld night vision viewing device. The assembly of the support frame has a hand wheel system to adjust the distance between the eyes of the left and right vision systems.
YJ4K is not only equipped with a battery on the rack of the main unit, but also equipped with an auxiliary power supply battery box, which is connected to the main unit through a standard DC cable. It comes with a battery pack of four 3 volt CR123A batteries which should power the unit for about 50-80 hours (without the IR on). The remote battery pack can not only supply power to the main unit, but also provide auxiliary functions as a counterweight. Considering that the main unit of the night vision device is heavy, a counterweight is required.
