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 image
