night vision optics
Night vision is an amazing technology. Being able to see clearly
at night on a moonless night is something supernatural. With night
vision optics, it won't matter how dark it is, you will be able
to see better and more clearly with night vision optics than with
any other instrument of chioce.
How to pick your Night Vision Device
Night vision monoculars are light, compact, and easy to
carry, plus they cost less than other night vision device types.
Night vision monoculars are good if you are going to be using it
to take pictures.
Night vision binoculars allow for better navigation as they
allow for both eyes to look through the device. With night vision
binoculars, you will experience less eye fatigue and better perception
of your surroundings. As you would imagine night vision binoculars
are heavier and more expensive than night vision monoculars.
Night vision goggles are handy as they allow your hands
to remain free at all times. Surprisingly, these may cost less than
night vision binoculars as they use only one image intensifier.
Night vision with 'video out' capabilities now allows for
the image to be recorded to an external device. These can be used
for wildlife observation, navigation, and surveillance. The image
can be copied to a device attached, or sent to a remote location
Night vision sights are used as weapon sights. Unlike night
vision monoculars, they have an additional device in the center
to make aiming easier.
Night Vision Generations
There are different generation of night vision optics. These generations
are technological additions to the previous generations. Since the
technology has been around for some time now, everytime the technology
advances in night vision optics a new generation is established.
The original night vision technology used in World
War II. This generation uses active infrared technology. What happens
is that a beam of near infrared light is projected, bounces off
objects and is returned to the night vision device lens. This technology
uses annodes and cathodes to accelerate the electrons, which can
distort the image.
This technology made changes to the type of technology
used. Instead of using the active infrared technology, the switch
was made to passive technology. This technology uses the natural
light given off by the moon and stars to produce greater amounts
of reflected infrared light. The problem with this technology is
that when it is cloudy or a moonless night, they don't fare so well.
To help with the problem of generation one, imporvements
to the image-intensifier tube were made. This improvement lead to
greater resolution and performance over the night vision devices
of generation one. The new technology allows them to be used and
produce adequate results on a night with less light, like a moonless
The technology remains the same between generations
two and gemeration three. The improvements came in image quality.
The night vision devices of generation three have better resolution
and are more sensitive than generation two did. The photo cathode
of generation three is made of gallium arsenide which converts photons
to electrons efficiently.
The most recent generation has advanced technology
that allows for better quality in both low- and high-level light
conditions. An ion barrier, that was added in generation three,
was removed, allowing more electrons to reach the amplification
stage allowing the images to be less distorted and brighter. An
automatic gated power supply was added allowing the photocathode
to rapidly switch on and off letting the night vision device to
perform well under light fluctuations.
Night Vision Types
There are different types or categories that night vision devices
may fall in. They are: Scopes, Goggles, and Cameras.
Night Vision Scopes
Night vision scopes are monocular devices that
may be mounted on other devices. These are a good device for looking
at specific objects for a period of time and then returning to normal
vision since they are handheld.
Night Vision Goggles
Night vision goggles are generally worn on your
head, but may be handheld if you prefer. They are binocular devices
that may have a single lense. This type of night vision device is
good when you want to remain using them. Instead of having to put
them up to your eye, and remove them like a nigh vision scope, night
vision goggles remain until you remove them from your head. This
is good if you will be using them for extended periods of time and
want your hands free.
Night Vision Cameras
Night Vision cameras are able to send the image
to a monitor or can be recorded with a VCR. This type of night vision
device is good when night vision is desired for a fixed location,
such as a building parking lot.

Buying Night Vision
When buying night vision devices, be sure to check what generation
of technology the device uses. Getting a cheap pair of night vision
goggles using generation 0 or generation 1 may lead to disappointment
if you are looking for the high sensitivity of earlier generations.
Make sure that you know the return policy before buying, night vision
devices can be expensive, and you don't want to be stuck with an
expensive toy that you don't like.
