NVG-Alpha Night Vision Goggles – L3 20UA White Phosphor Tubes

Filmless Clarity. Aviation-Grade Performance.

The NVG-Alpha with L3 20UA White Phosphor image intensifier tubes is a professional-grade night vision goggle system built around L3Harris’ renowned filmless tube technology and the lightweight, fully articulating NVG-Alpha housing. If you're looking for a step above “mil-spec,” this is it — aviation-grade tubes with a minimum FOM of 2000 and no maximum. These are hand-selected by L3 for flight crews and users who demand exceptional resolution, contrast, and signal clarity in dynamic environments.

The NVG-Alpha housing offers full articulation, pod shut-off, onboard IR, and manual gain control — and it’s built to be field-serviceable, lightweight, and rock solid. Paired with Carson mil-spec optics and your choice of dovetail mount, this is a goggle that’s as capable as it is comfortable.
