Harris ANVIS-9 (F4949 Series) is the gold standard in the world of night vision aviation optics. This specific system serves as the official and primary equipment for flight crews of the US Air Force (USAF) and the US Navy to support night operations.
Featuring the pinnacle of modern military-grade technology—the filmless/thin-film Gen 3 L3Harris MX-11769/UV (the most stringent military specification, OMNI VIII) Image Intensifier Tube—this device guarantees uncompromising clarity, a record-high FOM (Figure of Merit), minimal noise levels, and maximum detail under extreme conditions of critically low light.
Key Advantages and Features
-
Gen 3 OMNI VIII Image Intensifier Tube (IIT): The premium L3Harris MX-11769 tube equipped with Auto-Gating ensures the highest resolution and instantaneous adaptation to sudden light transits (muzzle flashes, sudden illumination). It demonstrates exceptional sensitivity in the near-infrared spectrum and a colossal operational lifespan.
-
Perfect Aviation Ergonomics: Complete freedom of individual customization. Independent adjustment of interpupillary distance, vertical and fore-and-aft (longitudinal) displacement, as well as tilt angle, allows the binocular to be perfectly adapted to any facial anatomy or helmet configuration.
-
Pilot Safety System (Auto-Detach): A unique mount featuring an automatic breakaway function under loads of 11 to 15 g reliably protects the pilot's cervical spine in the event of a hard landing, ejection, or emergency situation.
-
Advanced Optical System: Ultra-fast, high-speed lenses with the capability to install specialized aviation filters (Classes A, B, C, UK 645) for full compatibility with cockpit instrument panel lighting and Heads-Up Displays (HUD).

Field of Application
While the primary purpose of the ANVIS-9 system is night piloting of helicopters and aircraft, its advanced OMNI VIII standard IIT offering flawless clarity and a wide field of view makes this device highly sought after by Special Operations Forces (SOF) operators. It is ideal for executing complex ground tactical missions where spatial orientation, IFF (Identification Friend or Foe) target recognition, and reaction speed are critical factors.
Please note: The Harris ANVIS-9 built on the L3 OMNI VIII IIT is a top-tier, professional military asset. It requires appropriate operational proficiency to fully unlock the potential of third-generation filmless technologies.
