If you do some of your hobbies at night and you
need to see clearly in the dark, night vision
binoculars are what you need these are
binoculars that are designed to work in extremely
low light environments and they allow the user to
see quite clearly. There are different varieties
of bight vision binoculars and they are all able
to compensate for the human eyes inability to
see well during times when there isnt enough
light.
3
There are very advanced models of night vision
binoculars that are used for military
applications you can easily get nice civilian
versions or perhaps some retired military models.
You can easily buy your night vision binoculars
from online stores, science stores, and military
surplus stores or even from hunting suppliers.

Night vision binoculars generally work in two
distinct ways There are those that intensify the
scene being viewed passively through the lenses
while others actively scan the scene in order to
generate infra-red or thermal images. The first
night vision binocular models utilized the
passive technology while the more modern ones are
the active types that scan mages and this makes
them more sophisticated than the former.
5
The former passive system of night vision
binoculars has a generally wide lens opening so
that it can collect as much light as possible.
The light will then be channeled through a series
of light intensifying filters before it is
finally emitted through a tiny aperture this is
what allows the viewer to actually see in the
dark. Images coming through the passive system
have a greenish tint that comes from those lenses
that filter the light. Trying to correct the
green tone will general obscure the image and
that is the reason they are usually left
unaltered.
6
On the other hand, the active night vision system
has been designed to seek out for infrared
signatures so as to paint the signal for the
user. These are sophisticated night vision
binoculars that can deliver very clear images
the thermal imaging versions will display a scene
using blotches of color where the bright spots
will be indicating the hot points where a warm
engine or animal could be present.
7
The only downside of this model is that they
require a source of power and this could become
cumbersome especially when you are out in the
open. The advantage of the active system however
is that it is able to see through dust, fog,
smoke or any other source of visual disturbance
something that the passive system will not. Night
vision binoculars can be used for be used for
very useful applications such as what the
military uses when they have to scan for enemies
in extremely dim conditions.
