The QCNV Q4-A Gen2+ image intensifier tube is a high-performance optical component that delivers exceptional low-light imaging capabilities for mid-to-high-end night vision systems. Featuring a figure of merit (FOM) of 1600-1800, this advanced Gen2+ image intensifier tube produces sharp, clear images even in extremely low-light conditions, making it the ideal economical choice for professional users seeking superior performance at a competitive price point. With flexible interface options and compatibility with a wide range of night vision devices, the Q4-A offers unmatched versatility and value for system integrators and equipment manufacturers.
Our FOM 1600+ image intensifier tube boasts a resolution of ≥64 Lp/mm and a signal-to-noise ratio (SNR) of ≥25, delivering crisp, detailed images with minimal noise. The photocathode sensitivity of 750 μA/Lm ensures excellent light gathering capability, allowing the tube to operate effectively in near-total darkness. The luminance gain of ≥8000 Cd/㎡/lx amplifies even the faintest light signals, producing bright, clear images for enhanced situational awareness.
The Q4-A is available with both P43 (green phosphor) and P45 (white phosphor) options, allowing users to choose the phosphor type that best suits their specific application requirements. Green phosphor offers excellent contrast and reduced eye fatigue during extended use, while white phosphor provides more natural color perception and better detail recognition. The tube also features autogate technology and manual gain control, allowing users to adjust the image brightness and contrast in real-time to adapt to changing lighting conditions.
Constructed with high-quality materials and advanced manufacturing techniques, the autogate image intensifier tube is built to withstand harsh operating environments. It operates reliably in temperatures ranging from -45℃ to +55℃ and can be stored in temperatures as low as -45℃ and as high as +70℃. The tube features a durable AVG glass input window and an inverting spherical output window, ensuring long-term performance and durability.
The QCNV Q4-A image intensifier is widely used in security surveillance, law enforcement, search and rescue, wildlife observation, and outdoor recreation industries. It is the ideal component for manufacturing night vision goggles, monoculars, binoculars, and other night vision devices. Its superior performance and competitive price make it the preferred choice for system integrators, original equipment manufacturers (OEMs), and original design manufacturers (ODMs) looking to develop high-quality, cost-effective night vision solutions.
Handle the image intensifier tube with extreme care, avoiding direct contact with the optical surfaces.
Install the tube into the night vision device according to the manufacturer's instructions.
Connect the electrical interface, ensuring proper alignment and secure connection.
Turn on the night vision device and adjust the gain and brightness controls as needed.
Avoid exposing the tube to bright light sources when it is powered on, as this can cause permanent damage.
Keep the optical surfaces clean and free of dust, dirt, and fingerprints. Use a soft, lint-free cloth and lens cleaning solution to clean the windows if necessary.
Store the tube in a dry, cool place in its protective packaging when not in use.
Avoid dropping or subjecting the tube to mechanical shock, as this can damage the internal components.
Do not disassemble the tube, as this will void the warranty and may cause permanent damage.
