Theon NYX / Photonis 4G White Phosphor (P45) is a high-technology night-vision system that combines the European Theon Sensors NYX housing with Photonis 4G Gen 2+ image intensifier tubes engineered for maximum performance in low-light environments.
The Photonis 4G series represents the most advanced second-generation tubes, with real-world performance that often meets or surpasses baseline Gen 3 characteristics.
Its key advantage is universality and high sensitivity across an extended spectral range (350–1100 nm), enabling effective operation not only with natural light sources but also with 940 nm IR illumination, invisible to most traditional systems.
The 4G White Phosphor (P45) tubes feature minimal Halo ≤0.75 mm, high SNR ≈30, and deliver 64–72 lp/mm resolution with natural white-phosphor tonal reproduction.
