More Information :
Night Vision phosphor screen is purposefully engineered because the human eye can
differentiate more shades of green than other colors.
Why do you focus both the front (Objective lens) and Eyepiece (Ocular)?
You do not see through the Night Vision device, like a day monocular. Rather you see the
phosphor screen on the back of the tube. The objective lens focuses the image on to the front
of the intensifier tube. That image is then converted into electrons. The electrons strike the
phosphorous screen converting electrical energy into a visible image. The eyepiece focuses
your vision on to the image on the phosphorous screen.
What is the effective range of Night Vision?
Maximum range is up to 700 ft. depending on the model. The maximum viewing distance
depends on the environmental conditions. Overcast conditions, fog or rain will reduce the
effective distance you can see. The Infrared Illuminator will increase viewing range,
especially in areas of complete darkness where there is no ambient light.
What is the maximum effective distance of the Infrared Illuminator?
75 to 125 yds. The farther the object, the less intense the infrared light will be on the target.
When can I expose the unit to light?
For demonstration purposes there is a pinhole in the lens cap, which enables you to power on
the unit in the light. The lens cap can be taken off during daylight, but the unit has to be off.
What is Generation 1? How does it differ from other Generations of Night Vision devices?
Generation 1, 2, 3 and 4 all employ electron bombardment technology. All of these
technologies convert light into electrons and reproduce the image on a phosphorous screen.
Generation 1 produces a higher resolution image than Generation 2.
Generation 3 and 4 are used by the United States Military and are very expensive.
Generation 2, 3 and 4 use a fiber optic device and/or special chemicals to further amplify light.
Performance under Various Light Conditions
Complete Darkness
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.
Half-Moon
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.
Quarter-Moon
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.
How Night Vision Works
Light 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.
