Theon NYX / NoctuVision++ IIT is a versatile night-vision device that combines the European-built Theon Sensors NYX housing with high-performance NoctuVision++ IIT image intensifier tubes.
These tubes are engineered to deliver maximum contrast, stability, and image clarity in low-light environments.
NoctuVision++ IIT is a modern alternative to Gen 3 systems, offering FOM up to 2600, extremely low background noise (Low EBI), and high SNR, ensuring crisp imagery even with minimal ambient light.
White Phosphor P45 provides natural detail perception and reduces eye fatigue during prolonged operation.
With Ultra-Fast Auto-Gating, the system instantly adapts to lighting changes, protecting the user’s eyes and maintaining image stability under sudden exposure.
