Description
Description
The LUX3-6425W is a Generation 3 image intensifier tube designed for advanced night vision systems.
It features a GaAs photocathode and P43/P45 phosphor screen, delivering high resolution (up to 64 lp/mm), excellent signal-to-noise ratio, and superior low-light performance.
The rugged design ensures long service life (MTTF ≥ 10,000 hours) and reliable operation in harsh environments, with wide temperature and humidity adaptability.
With its compact dimensions (Ø 36.75 × 30.4 mm) and lightweight build, the LUX3-6425W is ideal for integration into night vision goggles, weapon sights, and surveillance systems requiring maximum clarity, brightness, and durability.
Product Introduction
This image intensifier tube is a 3rd-generation device featuring dual proximity
focusing, micro channel gain, a built-in auto-gating power supply unit (PSU), and
automatic brightness control (ABC). It offers an enhanced wavelength range of 400–
900 nm, delivers high starlight utilization efficiency, and exhibits excellent nearinfrared response. The tube is highly valuable for nighttime observation and other
applications under extremely low-light conditions.
