Developed to be a more durable and lightweight fixed bridge Night Vision Goggle, the Ruggedized Night Vision Goggle - 15 (RNVG-15) comes in an incredible 555 Grams while still being machined out of 7075 aluminum at the primary failure points in other fixed bridge night vision goggles. The RNVG maintains the familiarity of the AN/PVS-14 controls, with the same type of power switch, and the same optics, which allows the device to be turned on, off, and allowing the use of a single output IR Illuminator as well as the same method of focus the RNVG as the standard AN/PVS-14. Also, the RNVG-15 keeps a similar standoff between the dovetail interface and the bridge in order to allow optimal ocular alignment with a variety of helmet, mount and individual facial features. The unit is powered via one (1) CR123 battery or an auxiliary power pack. The RNVG is easily the lightest, most durable and cost effective NVG on the market today.
