How Do Infrared Binoculars Work?
Infrared night vision binoculars collect and amplify existing light, such as
moonlight, starlight or infra-red light, through the
objective lens, which is then focused on the image
intensifier. Inside the intensifier, a photocathode is “excited” by the light
and converts the photon energy into electrons. These
electrons accelerate across an electrostatic field inside the intensifier and
strike a phosphor screen (like a green monochrome TV
screen) which emits an image that you can see. It is the acceleration of
electrons, which provides gain and enhances the image. The image will be a clear
green-hued amplified re-creation of the scene you are observing.
All night vision binoculars need some light to amplify. Those binoculars with built-in infrared illuminators
(IRI), like the Bushnell
listed below, allows you to see in complete darkness where no
ambient light source, such as moonlight, is available. If the
subject is to be viewed in a completely dark area, you just activate
the infrared illuminator by pressing the IRI button. The IRI emits a beam of
infrared light that is nearly invisible to the naked eye, but will be bright
when viewed through the binoculars.
How Far Can I See With Infrared
Binoculars?
That depends upon how much ambient light is
present. For example, on a full-moon night, you should be able to see with no
problem out to the maximum distance of the binoculars' range which could be more
than 500 yards. In a completely dark area with virtually no ambient light
present, you will need to use the IR illuminator. The IRI will typically allow
you to see out to 100 yards or so.
Generation Night Vision Types
You will see the generation type listed in the specifications of your
binoculars or night optics. They range from 1st Generation thru 4th Generation
night vision with varying
levels of each in between. 1st generation is currently the most popular type of
night vision in the world. A 1st Generation unit will amplify the existing light
several thousand times letting you clearly see in the dark. These units provide
a bright and sharp image at a low cost, which is perfect, whether you are
boating, observing wildlife, or providing security for your home.
2nd Generation night vision goggles and above (Gen 3 night vision & Gen 4) is primarily used by law enforcement, military or
for other professional applications. This is because the cost of a Gen 2 night
vision unit
is approximately $500.00 to $1000.00 more then a Gen 1. The main difference
between a 1st and a 2nd Generation unit is the addition of a micro-channel
plate, commonly referred to as a MCP. The MCP works as an electron amplifier and
is placed directly behind the photocathode. The MCP consists of millions of
short parallel glass tubes. When the electrons pass through these short tubes,
thousands more electrons are released. This extra process allows 2nd Generation
units to amplify the light many more times then 1st generation giving you a
brighter and sharper image.

price compared to other sites.
Bushnell Infrared Binoculars Review
Exceeded my expectations.
"These binoculars were just as described, clear night vision with great
contrast. After several minutes use, it can be turned off and you can still see
for a long time, saving battery life." -George from Cypress, Texas

and pocket the savings:
There have been several occasions while camping or just in my own backyard where
we had our infrared binoculars out just for fun and caught some great up-close
glimpses of nocturnal avian life such as owls, nighthawks, nightjars and even
roosting birds like hawks and even songbirds. Of course there are kinds of nocturnal animals you can spot too without
scaring them away with flashlights. I've also used them on dark nights to walk
down paths or for finding items in my campsite without having to disturb others
by using a bright flashlight. I also enjoy looking at the stars and planets with
them - I know a telescope is better, but night vision binoculars are more
portable and I usually have them with me. I've also used to them when I heard
noises outside my tent to see it's only a raccoon and not a bear without waking
up everyone by using a flashlight.
We hope you enjoy your infrared binoculars as much as we do. We have additional
