BNVD-1431 / L3Harris 22UM is a professional night-vision system that combines the ergonomic, lightweight BNVD-1431 housing with high-performance L3Harris 22-series tubes (Unfilmed White Phosphor).
This is the “gold standard” of professional-grade Gen 3, delivering exceptional image clarity, fine detail, and high reliability in real field conditions.
The L3Harris 22UM / 22UA tubes are built on the same technological platform as contract-grade families, but adapted for civilian and aviation use.
They offer a high FOM (2300+), SNR above 30, stable performance under sudden lighting changes, and a very low background noise level.
This configuration is ideal for users who need the best balance between top-tier image quality and long-term durability.

Comment / quality level
The L3Harris 22UM / 22UA series represents a professional-class Gen 3 Unfilmed solution known for its high contrast, clean image field, and very low noise levels.
The unfilmed design eliminates the barrier layer between the photocathode and micro-channel plate, resulting in higher sensitivity and stable performance in extremely low-light environments.
These tubes handle bright-light flashes and rapid lighting transitions effectively thanks to fast Auto-Gating response.
L3Harris 22UM is the ideal choice for users seeking OMNI VIII–IX-level performance without contract-series export restrictions.
Who it is suitable for
Reconnaissance teams, instructors, and observation units operating in limited-light environments.
Vehicle and UAV operators who require stable imaging under changing illumination.
Security organizations and private operators working in variable urban or weather conditions.
Professional users, volunteers, and vehicle crews engaged in field and operational tasks.
Those who want performance approaching military-grade systems without paying for contract-only product lines.
