The N-15 uses optics that are equal to or better than current Military night vision units, built into a tough, compact and ergonomic composite housing. The Armasight Nyx-15 can withstand saltwater, rain, high humidity and temperature extremes and still provide unsurpassed levels of performance. For hands-free use, it can be worn on the included flip-up head mount or optional universal helmet mount, both of which have a built-in mechanism that will automatically turn the unit off when it is flipped up. The N-15 goggle is equipped with automatic brightness control, bright light shut-off circuitry and a spot/flood built-in IR illuminator. The N-15 is equipped with LED indicators that are displayed on the screen of the eyepiece to alert the user of a low battery, or to indicate that the IR is turned on. The dismounted goggle can also be utilized as an excellent long-range viewer with an optional 3x afocal lens. The Armasight N-15 utilizes two image intensifier tubes.
