The Kestrel 4000NV was improved to make it even more suitable for military use.

The Kestrel 4000 NV is olive drab with a visible red backlight - which helps users to sustain natural night vision. The NV’s red backlight preserves the natural night vision of users such as military personnel and pilots. It takes 30 to 45 minutes for the average eye to adapt to darkness and maximize night vision. Even a short burst of white, yellow, green or blue light “bleaches out” the rod cell photoreceptors in the eye and causes night blindness until the entire adaptation process can take place again. Light in the red spectrum does not cause this “bleaching out”, preventing night blindness and night vision fatigue. This unit’s red backlight is also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations.
