Product Overview
The Q4-B image intensifier tube is a high-performance Gen2+ low-light imaging component engineered for mid-to-high-end night vision systems. Delivering a minimum FOM1400+ rating (1400-1600 range), this tube combines exceptional resolution, low noise characteristics, and reliable operation across extreme temperatures. Available with both P43 green and P45 white phosphor options, it produces crisp, distortion-free images in near-total darkness. Designed with cost efficiency in mind, the Q4-B Gen2+ image intensifier tube outperforms comparable imported alternatives while maintaining competitive pricing, making it the preferred choice for industrial buyers, system integrators, and equipment manufacturers seeking balanced performance and value.
Core Advantages & Features
Superior Low-Light Imaging Performance
Equipped with a Na2KSB(Cs) photocathode delivering 650 μA/Lm sensitivity and ≥64 Lp/mm resolution, the FOM1400+ image intensifier tube captures fine details even in extremely dim conditions. Its signal-to-noise ratio (SNR) of ≥22 ensures minimal image grain, while a luminance gain of ≥8000 Cd/㎡/lx amplifies faint light sources to produce bright, usable visuals.
Flexible Configuration Options
The low-light image intensifier supports multiple power supply modes including non-gated, gated, external gain adjustment, and external brightness adjustment. It also offers both touch type and lead type electrical interfaces, allowing seamless integration into diverse system designs. Users can select between P43 green phosphor for traditional night vision viewing or P45 white phosphor for enhanced contrast and reduced eye fatigue during extended use.
Exceptional Durability & Reliability
With an operating temperature range of -45℃ to +55℃ and storage temperature range of -45℃ to +70℃, the Q4-B night vision tube withstands harsh environmental conditions. Its robust construction ensures long service life, while low power consumption (≤20 mA at 3V) extends battery life in portable devices.
Broad Compatibility
The tube is fully compatible with QVS7, QVS31, QVS14, and QVS18 night vision systems, enabling easy upgrades and replacements without extensive system modifications.
Applications & Suitable Scenarios
The cost-effective image intensifier tube is ideal for a wide range of professional applications:
Security & Surveillance: Perimeter monitoring, critical infrastructure protection, and nighttime patrol systems
Outdoor Equipment: Nighttime navigation devices, wildlife observation systems, and search-and-rescue gear
Public Safety: Law enforcement patrol equipment, emergency response systems, and border control monitoring
OEM Manufacturing: Integration into night vision goggles, monoculars, binoculars, and vehicle-mounted systems
Operation & Maintenance Guide
Ensure proper voltage supply (2.2-3.4V) to avoid damaging the tube
Avoid exposing the tube to direct bright light when powered on, as this can cause permanent damage
Clean the input and output windows with a soft, lint-free cloth to remove dust and smudges
Store the tube in a cool, dry place when not in use, away from extreme temperatures and humidity
Handle the tube with care to avoid physical impact, which can damage internal components
