Description
The Alpha Optics AO-MUM-14A Gen 3 is a high performance modular, hand-held passive night vision monocular device that utilizes a single Generation 3 intensifier tube to provide crisp, clear images under the darkest conditions. Its “single tube / single eyepiece” approach to night vision missions is based upon the proven concept that independent use of each eye maximizes the ability to operate under a wide range of low light conditions maintaining optimal situational awareness and flexibility of equipment applications.
Small, lightweight, and versatile, the AO-MUM-14A gives you a high-performance 3rd generation system in the smallest package available. With its unique electronic switch performance, it does not require an adapter to convert from AA to CR123A batteries. The AO-MUM-14A can be weapon mounted, head/helmet mounted, handheld, or optionally attached to cameras and extender 3x/5x afocal objective lenses. Also available a dual-system head/helmet mount that allows two AO-MUM-14A’s to become one binocular system. The on-axis rail system permits the Alpha Optics AO-MUM-14A Gen 3 to use a wide range of mounting options.
