BNVD-SG (Binocular Night Vision Device — Single Gain) is a high-grade binocular night-vision system equipped with L3Harris 22UM / 22UA White Phosphor image-intensifier tubes.
This configuration belongs to the professional Gen 3 Unfilmed class, delivering a high FOM of 2300+, excellent clarity, minimal noise, and outstanding performance in low-light environments.
Thanks to Unfilmed tube technology, the IITs provide higher photosensitivity and faster response to lighting changes, making the BNVD-SG in this configuration an ideal solution for field applications and reconnaissance tasks.

Comment / Quality Level
The L3Harris 22UM and 22UA series belong to the class of professional Unfilmed White Phosphor tubes with high SNR (≈30+) and RES (≥64 lp/mm).
A FOM above 2300 ensures stable performance under starlight or minimal moonlight, delivering excellent detail with virtually no visible grain.
White-phosphor imaging provides a natural visual experience with soft contrast and realistic shape perception.
Suitable For
• Professionals working in night-time conditions with elevated image-quality requirements.
• Engineering, aviation, and security units that require a clear, low-noise image in all operating environments.
