NIGHT VISION
Without getting too technical and confusing, let’s try to understand
how this device works and what it can and cannot do:
1. Your night vision device works on the principle of amplifying
(intensifying) available light. The process is called light
amplification. A special tube inside the device does the job – all
you have to do is to power the device on and the tube starts
amplifying whatever the light is available at the moment –
therefore it is important to understand that this device is not
suitable for daylight operation, since there is already enough
light available during daytime to see without any additional
help. Therefore, the first and most important rule of any
night vision device is – never use it during daylight, or in
any bright light condition, which allows you to see well
with your naked eye!
2. Your night vision device operates with batteries. Unlike a
daylight binocular, where you see the image due to light
traveling through the glass and the prisms, the night vision
device works by projecting the amplified image onto a screen.
While the tube is the crucial component of any night vision
device, the optical parts of the unit are also very important, as
they gather the light into the tube and bring the projected
image to your eye. Since the image is projected on the screen,
just like any TV, it has certain limited resolution…so please do
not expect your night vision device to provide the same crystal
clear image, as you see through your daylight binoculars – after
all, you are using this device in the dark environment, where
normally your vision would be very limited…oh, and another
important point – all night vision devices have green
monochrome image – why green? Because human eye can
distinct most details of the viewing image when presented in
green color…other colors do not show you everything…
3. Another very important notice – since your night vision device
amplifies available light hundreds or even thousands of times –
please be sure not to turn the unit on during daylight or in a well-
