Description
High Performance with Image Intensifier Tube 4G+
The Image Intensifier Tube 4G+ is a powerful advancement in night vision technology, engineered to meet the rigorous demands of defense, surveillance, and security operations. Developed by Exosens, this tube is optimized to deliver consistent and high-quality imaging across diverse and challenging environments.
With a minimum Figure of Merit of 2300, the Image Intensifier Tube 4G+ provides exceptional image clarity and reliability. This high FOM ensures better contrast and sharper details, enabling operators to detect and recognize objects with improved accuracy in low-light conditions.
Enhanced Sensitivity
The Image Intensifier Tube 4G+ stands out with its extended spectral sensitivity ranging from 350 nm to 1064 nm. This wide bandwidth allows users to operate effectively across various environments, from urban landscapes to dense forests, and in conditions such as rain, fog, or smoke.
Its ultra-fast auto-gating capability plays a critical role in adapting to rapidly changing light conditions. Whether transitioning from dark to bright areas or encountering sudden light exposure, the tube maintains optimal image quality without distortion or delay.
Precision Imaging
Another key advantage of the Image Intensifier Tube 4G+ is its reduced halo effect, which minimizes glare around bright light sources. This results in clearer and more precise visuals, especially in complex environments where multiple light sources are present.
The tube delivers a limiting resolution of up to 72 lp per mm and maintains strong performance even under higher light levels. Combined with a signal-to-noise ratio starting at 30, it ensures crisp and low-noise imaging that supports accurate decision-making.
Its lightweight design makes it ideal for integration into portable systems such as soldier equipment, surveillance devices, and mobile platforms. With flexible phosphor options including P43 green and P45 white, users can select configurations based on their operational needs.
