BNVD-SG (Binocular Night Vision Device – Single Gain) is a professional third-generation night-vision binocular (Gen 3 Unfilmed) equipped with L3Harris 24UM / 24UA White Phosphor image-intensifier tubes.
The system delivers exceptional image quality with an elevated FOM of 2466+, low noise, and stable performance even in near-total darkness.
Thanks to Unfilmed tube technology, the IITs offer enhanced photosensitivity, a cleaner field of view, and rapid adaptation to lighting changes, making the BNVD-SG with the L3Harris 24-series one of the most optimal configurations for professional use.

Comment / Quality Level
The L3Harris 24UM and 24UA tubes belong to the upper tier of Unfilmed Gen 3 systems with FOM 2466+, delivering exceptional detail even under starlight or completely moonless conditions.
They feature a high Signal-to-Noise Ratio (≈ 33–35) and resolution above 70 lp/mm.
These tubes are notable for their field uniformity, absence of visible grain, and stable performance without “bleeding” effects during brightness transitions.
White-phosphor imaging provides a natural scene perception, minimizes eye fatigue, and allows the operator to assess the environment more quickly in darkness.
This performance class is commonly found in L3Harris aviation, observation, and search-and-rescue systems built to contract-grade standards.
Suitable For
• Professionals requiring the highest image quality and operational stability in field conditions.
• Reconnaissance operators, UAV crews, and observation units.
• Instructors, pilots, strategic-facility security personnel, and users working in total darkness without auxiliary illumination.
• Users who prioritize field uniformity, high contrast, and precise detail rendering without visual fatigue.
