Description
The AGM UNVG-51 3AL1 Night Vision Goggles (AGM item 12UN512941143111, UPC 810164390271) is a lightweight dual-tube night vision goggle with independently moving tube pods fitted with a Gen 3 auto-gated Level 1 image intensifier tube with a green P43 phosphor screen. Gen 3 brings a gallium arsenide photocathode for high sensitivity in very dark conditions, and auto-gating rapidly cycles tube power so the image stays usable and the tube stays protected when lights or muzzle flash appear. Level 1 is AGM’s entry Gen 3 grade.
AGM UNVG-51 3AL1 Night Vision Goggles Overview
The UNVG-51 is the wide-angle version of AGM’s ultra-light dual-channel goggle. Its 19mm F/1.26 multi-coated objective lenses widen the view to 51 degrees at 1x, compared with 40 degrees on the standard UNVG, so you see more of the trail, tree line or room without turning your head. Two image intensifier tubes give true binocular vision with natural depth perception, and the compact composite housing weighs about 1.1 pounds (500 g). Focus runs from 0.25 meters to infinity.
A single AA battery in the housing runs the goggle for up to about 15 hours. The included external battery pack, worn on the back of a helmet, extends that to about 50 hours on four AA cells or about 30 hours on two CR123A cells, and it doubles as a useful counterweight.
Image Intensifier Tube
The 3AL1 configuration is the part of this listing that sets it apart from other UNVG-51 versions: a Gen 3 tube with green phosphor. Note: photos show the UNVG-51 housing, which is identical across tube options.
AGM grades its tubes by resolution and image cleanliness. For the exact resolution, figure of merit and blemish specification of the tube in this unit, check the AGM datasheet or ask us before you order.
Controls and Features
Gain is set manually to match the conditions, and each tube pod moves independently, so you can run both eyes or flip one pod aside to keep one eye unaided. Each tube switches off automatically when its pod is turned sideways, which saves battery and avoids eye glow.
An integral infrared illuminator provides close-range light for reading maps or working with gear in total darkness. The goggle fits standard dovetail headsets and helmet mounts, and diopter adjusts from -6 to +2.
What Is Included
The box includes the goggles, a remote battery pack, a connecting cable with battery adapter, two demist shields, two sacrificial windows, a neck strap, carrying case, lens cloth, user manual and an AA battery.
Who Benefits Most
This version suits hunters and security users who need Gen 3 low-light sensitivity, people working near roads, yard lights or flashlights where auto-gating helps, and buyers who like the classic green view.
Honest Limitations
A wider field of view spreads the same tube resolution over a larger scene, so fine detail at distance is slightly less sharp than with a 40 degree lens. Dual-tube goggles cost more than a single-tube monocular because you are buying two tubes, and a head or helmet mount is sold separately.
Runtime on the internal AA cell is modest, so plan to carry the battery pack for long nights. Night vision image intensifiers are export-controlled and sold for use within the United States. Check AGM’s current warranty terms before you buy.
