Forty years of image intensifier technology. The gear that changed how wars are fought — and what it took to build it.
Night vision didn't start with a Gen 3 PVS-14. It started in 1939 with an active infrared device the size of a suitcase that needed a dedicated IR searchlight to work. The technology evolved through four decades of military investment, tube manufacturing breakthroughs, and hard lessons from Vietnam, Panama, and the Gulf — and the result is the Gen 3 image intensifier that defines modern night operations.
Adams Industries has been in and around this technology since 1994. Over that time, we've accumulated a collection of devices, documentation, and components that represent the full arc of image intensifier development — from first-generation starlight scopes to modern autogated Gen 3 tubes. This is that collection.
The museum is a working reference, not a display case. Every device here was operational at some point. Some still are.
Gen 1 devices amplify available ambient light — moonlight, starlight, artificial light — using a cascade of image intensifier stages. Image quality degrades toward the edges, and performance drops sharply in very low ambient light. But in 1963, it was revolutionary. The AN/PVS-2 Starlight Scope was the first fielded NVG and changed infantry tactics in Vietnam.
The original fielded night vision scope. A three-stage cascade image intensifier optimized for 500m–1000m observation and aimed fire from the M14 and M16. The PVS-2 saw service through the early 1980s.
Weight: 3.0 lbs. Gain: ~20,000× ambient. The IR searchlight was optional — this ran on available starlight, which was genuinely new in 1963.
The first widely fielded binocular NVG for US forces. A Gen 2 device that used second-generation microchannel plate (MCP) tubes and was standard issue through the 1980s. Heavy, with image distortion, but transformative for dismounted infantry operations.
The PVS-5 was the primary US military NVG during Grenada, Panama, and early Gulf operations — before Gen 3 tubes became available at scale.
Generation 2 introduced the microchannel plate — a glass disk with millions of microscopic channels that multiply the electron signal from the photocathode. This eliminated the cascade of tubes required by Gen 1, dramatically reducing size and weight while improving resolution and low-light sensitivity. Gen 2 devices remain in service worldwide.
The PVS-7 moved from Gen 2 to Gen 3 tubes in US military service but remained in export production with Gen 2 tubes for foreign military sales. A binocular goggle with a central objective lens and prism-split image delivered to both eyes — mechanically simple, optically adequate, operationally proven.
Still in service with dozens of militaries. Adams Industries has sold, serviced, and rebuilt PVS-7s for over two decades.

The M845 represents Litton's transition-era Gen 2 production — the tubes that preceded the Gen 3 gallium arsenide photocathode designs that Litton pioneered.
Adams Industries has original Litton factory documentation and period brochures for this lineage in the collection.
Generation 3 replaced the multialkali photocathode with a gallium arsenide (GaAs) photocathode, dramatically increasing sensitivity in near-infrared wavelengths (700nm–900nm) — the spectrum where IR lasers and illuminators operate. Combined with an ion barrier film to extend tube life and autogating to handle bright light sources without blooming, Gen 3 defines current operational capability.
The AN/PVS-14 is the current US military standard individual NVG and has been since 2000. Modular, helmet-mountable, and adaptable for weapons use, the PVS-14 replaced the AN/PVS-7 in US service and is the most widely fielded Gen 3 device in the world.
Adams Industries has built, serviced, and configured more PVS-14s than we can count. The device in the museum is a fully functional example representative of current US specification.

Issued to US forces during Desert Storm and through the 1990s, the 7B represents the transition era when Gen 3 tube availability was sufficient for wide fielding but before the monocular configuration of the PVS-14 became dominant.
View current PVS-7 →The standard Gen 3 tube uses a green phosphor screen — green because early research found operators could resolve fine detail better under green illumination in low-light conditions. White phosphor replaces that screen with one that renders the image in grayscale, which many operators find provides superior contrast and more natural vision in mixed-light environments.
White phosphor is now the preferred configuration for most professional and government procurement. Adams Industries offers white phosphor options across multiple platforms.
