YM-NVG18N panoramic night vision device is a panoramic night vision device (YM-NVG18N) innovatively developed by Ditai Optoelectronics with ground panoramic night vision observation capabilities. The purpose of the YM-NVG18N is to provide the user with more information in a night vision environment, allowing him to pass the OODA loop (observe, orient, decide, act) faster. The most notable feature of the YM-NVG18N is that it has four independent image intensifier tubes and four independent objective lenses arranged in a panoramic direction. The two middle lenses point forward like traditional binocular night vision, giving the user more depth perception, while the other two lenses 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. Users see the two central images overlapped with the two outer images, resulting in an unprecedented 120° field of view.
This is an absolute game changer for night vision gear. The two imaging systems on the left and right are mounted side by side on the support frame and suspended on a holder similar to the ANVIS night vision helmet, providing the user with complete adjustment options. They can also be easily detached from their mounts as stand-alone handheld night vision viewing devices. The support frame assembly has a handwheel system that can adjust the eye spacing of the left and right visual systems.
YM-NVG18N is not only equipped with a battery on the host rack, but also equipped with an auxiliary power supply battery box, which is connected to the host through a standard DC cable. It comes with a battery pack that accepts four 3-volt CR123A batteries, which can power the unit for approximately 50-80 hours (without the IR on). The remote battery pack can not only power the host, but also provide auxiliary functions as a counterweight. Considering that the night vision device host is heavy, a counterweight is required.
