NOX sights are designed and built in the USA using the best commercially available BAE thermal imaging cores and the highest grade optical components. The 640×480 12 micron core from BAE operates at 60 Hz for a crisp, clear image in a wide range of environments. The detection range is nearly 1500 yards with the 35mm lens.

NOX sights can be user-configured for the right or left eye, and can be dual-mounted with another NOX sight or with a night vision monocular, such as PVS-14. Weapon and/or dovetail mounts are removable to reduce the size and weight of the unit.

Each NOX sight ships with a standard CR123 battery and a rechargeable 18650 battery (and charger). Depending on ambient temperature, run time is up to an hour and a half with a standard CR123 battery, and from four to seven-plus hours with the rechargeable 18650 battery. For the ultimate power solution, NOX sights can be powered with an external USB battery bank via the provided USB-C cable.

Five highly ergonomic control buttons permit immediate access to frequently used functions (calibration, polarity, zoom, photo, power), as well as access to the user-friendly menu system for zeroing and/or customization of device parameters. This includes a standalone calibration button that provides the user with the ability to calibrate the unit with one hand in under one second.
