The NightVue, from Axeon, is a binocular-mounted green laser illuminator, which transforms a standard set of binoculars from being a daytime-only tool, to a round-the-clock optic. Mounting to most porro- and roof-prism binoculars, the NightVue beams a 520 nm green laser out to 250 meters. The green hue is intended to cut through haze and fog, while also having a limited effect on night-vision. It is also designed not to disturb animals in its path.
Once mounted with included hardware, a beam-adjustment wheel changes the angle of light output, to match the magnification range of the binoculars, and the distance of the subject. A locking knob on the mounting stem, meanwhile, can be loosened so the laser can be aligned with the binoculars' line of sight.
