ATN PVS-31 / L3Harris 20UM / 20UA FOM 2000+ Night Vision Binocular

White Phospor

FOM 2000+

The combination of the ATN PVS-31 housing with L3Harris 20UM / 20UA tubes represents a versatile, professional-grade Gen 3 Unfilmed White Phosphor configuration.
The 20UM / 20UA series delivers noticeably improved image cleanliness, contrast, and stability compared to the baseline 18UM / 18UA generation, while maintaining a reasonable cost level.

The PVS-31 housing adds ergonomics, low weight, independent pod articulation, and the ability to operate from an external power source.

Comment / Quality Level
The 20UM / 20UA series represents a clearly noticeable step forward from 18UM:

• a higher signal-to-noise ratio produces a cleaner image;
• improved contrast enables faster object identification;
• lower EBI enhances performance in near-total darkness;
• the inherent stability of the unfilmed architecture improves operation near light sources.

In the ATN PVS-31 housing, this optical configuration demonstrates high effectiveness in real field-use scenarios and provides comfortable long-duration observation.

Suitable For
• Observation operators who require a cleaner and more contrast-rich image than entry-level series.
• UAV operators working in minimal ambient light who require high-quality detail recognition.
• Facility-security units that prioritize reliability and proven Gen 3 Unfilmed stability.
• Users migrating from XLS / XLSH or Photonis systems who want L3Harris image cleanliness.
• Mobile teams operating in variable lighting environments.
• Civilian users seeking high-level L3Harris performance without the cost of full contract-grade series.
