very sophisticated binoculars for surveillance or night navigation to simple
binoculars for kids to have fun with. How do you know what features would be

binoculars for you.
Use of night vision binoculars
There are many ways you can use a night binoculars. Here are the most popular
ways people use binoculars with night vision.
Many night vision binoculars work similar to digital cameras, they have a built
in flash. The size varies a lot - smaller binoculars are more expensive, but
they might be just as powerful as the big ones. When choosing a night binocular
first decide what you are going to use it for. If it just for the kids to play,
then go with a less expensive model that they will not break easily. If you
are going to use the binoculars yourself go for a higher quality optics which
naturally would cost more.
How night binoculars work?
Optics in night vision binoculars amplifies the existing light. They use not
only light visible to our eyes, but also infrared spectrum. Quality night binoculars
have an infrared illuminator which increases the available infrared light.
All things you see through a night binocular appear green, because you don't
look directly at the objects but at their image on a phosphor screen.
Depending on light conditions at night binoculars perform differently. You
will not see anything if there is no single star in the sky and no street lights.
The lower the light situation is, the more powerful night binocular you will
need. You can get Gen 1, Gen 2 and Gen 3 night binoculars. Gen stands for generation.
Gen 1 are all right during a night with full moon and bright stars. For a crescent
moon Gen 2 works better, and for a dark cloudy night you will need Gen 3 binoculars.
Generation 1 night binoculars are affordable, Gen 2 and Gen 3 binoculars are
much more expensive.
Kids enjoy night vision binoculars
If you are going on a long trip, a night vision binoculars will be excellent
entertainment for kids. They will stare in the windows for hours and discover
many thing that otherwise would be missed.
When it comes to binoculars you always get what you paid for. Brand name binoculars
like Yukon, Night Owl, Weaver or N-Vision Optics cost more, but they come with
more features. Also be aware, that night binoculars cost much more than ordinary
binoculars.
Night vision range
The range of you binocular depends on three things - its gain, resolution and
magnification. If you have powerful lenses, the magnification is good, but the
amount of captured light decreases significantly. Usually only magnification
below 5X works well for night binoculars. So unlike ordinary day light binoculars
the range for night ones is not that extended.
Night vision monocular - another option
Night vision binoculars are very comfortable to use because we are accustomed
to seeing with both eyes, but they are pricey. If you want powerful night vision
optics for a cheaper price, consider night vision monocular. The result you
get is pretty much the same, but they cost significantly less.
Another way to save is to look for binoculars online. Sometimes you can buy
them on the Internet cheaper than in the stores.
