Q4 image intensifier tube
Factory-direct IIT for night vision OEMs and military projects – 15+ years experience, stable lead time, OEM/ODM support.
Q4-A
Q4-A adopts Gen2+ with FOM≥1600, ≥64 Lp/mm and ≥25 SNR, P43/P45 options and flexible interfaces for sharp low-light imaging; its superior price-performance makes it the optimal economical choice.
The Q4-A offers a far more cost-effective solution than comparable imported tubes for military and police, security surveillance, outdoor equipment, and OEM manufacturers, making it the rational first-choice configuration for today’s mid- to high-end low-light night vision systems.
Compatibility:QVS7/QVS31/QVS14/QVS18
Certified:
Q4-B
Q4-B image intensifier tube adopts Gen2+ technology with FOM≥1400, high resolution and low noise, offering clear green/white images (P43/P45) and flexible interfaces for reliable low-light performance. Its optimized design, long lifetime and controlled cost deliver outstanding price-performance, making Q4-B the preferred choice where both efficiency and economy matter.
The Q4-B offers a far more cost-effective solution than comparable imported tubes for military and police, security surveillance, outdoor equipment, and OEM manufacturers, making it the rational first-choice configuration for today’s mid- to high-end low-light night vision systems.
