The NVMT range features a Yukon Certified Gen 1 image intensifier tube and multicoated objective lens, partnered with Yukon’s special multicoated optics, bring a crispness and clarity to the nighttime experience.
Night Vision - How it works
Light (like moonlight or starlight) coming into the device from the direction of the object is gathered by the objective lens and focused onto the Image Intensifier Tube.
The front of the Image Intensifier Tube contains a photocathode which converts light into electrons. The device contains a very high voltage power supply, which converts the 3 volts supplied by the batteries into 17 kilovolts.
The high voltage hurls the electrons into the phosphorous screen. The phosphorous screen illuminates with an image when struck by electrons. The eyepiece optic then focuses the phosphorous screen image to your eye
Your Night Vision device works by amplifying available natural light. In complete darkness, with no available natural light, you cannot see without the use of the Infrared Illuminator (IR). The IR works like a flashlight, but is invisible to human and animal eyes.
A half-moon provides a substantial amount of ambient light to be amplified by the internal Electronic Intensifier Tube. Without the assistance of the IR, you can recognize a man-sized object about 100 yards away.
A quarter-moon provides the minimal amount of ambient light to allow viewing unassisted by the IR. Without the IR illuminated, a man-sized object can be recognized about 60 yards away. With the IR illuminated, this distance is more than 100 yards. The IR will greatly improve target recognition.
Urban Environment (with man-made light sources)
Streetlights and headlights will generally not damage the Electronic Intensifier Tube, if a safe distance away. As a precaution, do not point the device directly into a light source. At a distance of more than 30 yards, most common man-made light sources will generally not damage the device though it is still not recomend that a device be pointed toward them..
