NVGA-15 / L3Harris Contract Series is a premium-grade Gen 3 White Phosphor configuration built on contract-spec image-intensifier tubes from the 1597, 1610, and related series manufactured for U.S. government and allied defense programs.
These tubes are considered a benchmark of quality and stability, setting the performance standard for subsequent generations of night-vision systems.
The L3Harris contract-grade tubes undergo a full calibration and selection cycle, ensuring a perfectly clean image field, stable FOM above 2300, high contrast, and minimal defect levels.
The NVGA-15 housing fully unlocks the potential of these tubes, providing excellent ergonomics, balance, and compatibility with professional helmet-mounting ecosystems.

Comment / Quality Level
The 1597, 1610, and related L3Harris contract-series tubes are a reference standard for precision, clarity, and stability in Gen 3 White Phosphor imaging.
Each tube undergoes military-grade certification and meets aviation and ground-operations requirements.
High SNR, minimal halo, and consistently high resolution place these tubes among the best non-export commercial configurations available.
Integrated into the NVGA-15 housing, they form a system closely approaching MIL-SPEC-class professional solutions.
