Description
Reliable Performance with Image Intensifier Tube 4G
The Image Intensifier Tube 4G is a trusted solution in modern night vision systems, widely adopted across global defense and surveillance programs. Developed by Exosens, this technology has established itself as a benchmark over the past decade by delivering consistent performance in complex and demanding environments.
With a minimum Figure of Merit of 1800 and typical values reaching 2100, the Image Intensifier Tube 4G ensures clear, detailed imaging even in low-light conditions. This high level of performance enables operators to detect and identify targets effectively, enhancing situational awareness and operational efficiency.
Enhanced Visibility
The Image Intensifier Tube 4G features an extended spectral sensitivity ranging from 350 nm to 1064 nm. This wide bandwidth allows the system to capture more photons across varying lighting conditions, from twilight to near-total darkness. As a result, users benefit from improved visibility in challenging environments such as urban settings, dense forests, and adverse weather conditions.
Additionally, this technology enables detection of 1100 nm laser target designators, providing a tactical advantage that is critical in modern operations.
Precision and Flexibility
Equipped with fast auto-gating, the Image Intensifier Tube 4G quickly adapts to sudden changes in light intensity. This ensures consistent image quality and protects the system from overexposure in dynamic environments.
The tube delivers a limiting resolution of up to 72 lp per mm and maintains strong performance under higher light levels. Combined with a signal-to-noise ratio of up to 30, it produces sharp, low-noise images that support accurate decision-making.
Designed for versatility, the Image Intensifier Tube 4G is available in both 16 mm and 18 mm formats, making it suitable for a wide range of applications including portable soldier systems, vehicle-mounted platforms, and surveillance equipment. Its lightweight construction further enhances usability without compromising durability.
