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
