NVGA-15 / Photonis 4G P45 is a high-technology night-vision system that combines the NVGA-15 housing with the most advanced European image intensifier tubes — Photonis 4G.
The 4G series is the gold standard of the Gen 2+/Hybrid Gen 3 segment, known for exceptional contrast, high FOM up to 2800, rapid response to lighting changes, and extremely low halo.
White Phosphor P45 provides natural scene perception and enhanced detail clarity during long-duration observation.

Comment / Quality Level
The Photonis 4G series represents the top tier of European image intensifiers — in several parameters rivaling Gen 3 units from L3Harris and Elbit.
4G tubes provide:
-
high contrast and extremely low noise;
-
instant adaptation to lighting changes — ideal for dynamic environments;
-
neutral, daylight-like imaging from the P45 phosphor, reducing eye fatigue during prolonged use.
Installed in the NVGA-15 housing, this system offers an excellent balance of weight, ergonomics, and performance — one of the best combinations for professional-level users.
Suitable For
-
Operators and instructors who require precision imaging and stability under all conditions.
-
Observers, pilots, and UAV operators working at night.
-
Security and rescue units where reliability and image clarity are essential.
-
Researchers, geologists, and hunters needing adaptive, flare-free night vision.
-
Volunteer programs supplying professional-grade equipment with high quality at an accessible price.
