BNVD-1431 / Elbit YH is a high-end night-vision system combining the BNVD-1431 housing with Elbit YH (Gen 3, White Phosphor) image intensifier tubes.
This configuration delivers maximum stability, high contrast, and exceptional detail clarity, enabling effective operation even in the most demanding night conditions.
Elbit YH tubes belong to the Ground Spec combat standard, used in U.S. and NATO military systems.
They feature a high FOM of up to 2700, low noise levels, minimal Halo, and strong resistance to sudden illumination changes thanks to high-speed auto-gating.

Comment / Quality Level
The Elbit YH series represents the Gen 3 class used in U.S. combat-grade systems.
It is characterized by high contrast, deep black levels, sharp fine detail, and stable performance under extreme temperatures.
These tubes feature minimal Halo and very low EBI, keeping the image exceptionally clean even without IR illumination.
This configuration is intended for users who require combat-grade accuracy, durability, and predictable, repeatable optical quality.
Suitable For
-
UAF units, reconnaissance teams, and special-equipment operators needing maximum efficiency in field operations.
-
