The NOX18 is a small, compact 12 micron 60Hz refresh rate thermal monocular. It can be easily attached to a helmet or used for scanning. This very unique product was designed and built in the USA. The highest quality thermal imaging cores and optical components are used to manufacture the NOX18. Nox is available in an 18mm or 35mm lens configuration, allowing for the best magnification and field of view combination, depending on your environment. On a helmet, the NOX can be mounted on either side for a view through your right or left eye. You can pair this unit with another thermal or a singular night vision optic like a PVS-14.

Each NOX ships with a standard CR123 battery and a rechargeable 18650 battery (and charger). Depending on ambient temperature, you can expect up to an hour and a half of run time with a standard CR123 battery and from four to seven plus hours on the rechargeable 18650 battery. For the ultimate power solution, Nox can be powered with an external USB battery bank via the provided USB-C cable. NOX has five highly ergonomic control buttons that permit immediate access to the frequently used functions (calibration, polarity, zoom, photo, power) and allow 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.
