An Introduction for Consumers
Famous Trails

night vision scopes enable the user to view
objects when it is normally too dark to see with the naked eye.
The device amplifies the photons from any available light by
collecting it through the objective lens and focusing it on the
image intensifier. A photocathode within the intensifier converts
the photon energy into electrons; they in turn move with increas-
ing speed across an electrostatic field and hit a phosphor screen.
This increasing speed of the electrons provides gain and creates
a visible image, which is displayed on the phosphor screen.

systems make it easier to view objects when
there is very little light, but cannot work in total darkness. In this
situation an infrared illuminator can be used to provide light,
enabling the Famous Trails
®
system to amplify it. The infrared
illuminator can also be used in lowly lit areas, enhancing images
in changing light conditions with consistent performance. These
infrared illuminators are available on all of

night
vision products.
When testing night vision products, Famous Trails

measures
the quality of the image, the range of the product and gain.
Because it is difficult to make out smaller details if long distances
or low lighting are factors, systems with extreme gain and high
resolution are enormously expensive. The reasonably priced
Famous Trails
®
system was created to suit a user’s most common
needs providing a viewer with a clear, detailed image. Take a
night vision device along on your camping or boating trips to
enable you to view wildlife with amazing clarity or use it to
enhance security around your home.
As you review the literature for products like

system, you will find that understanding the specifications of
how our system measures up is sometimes dif

when talking about actual use in the field. It is important to
understand what is meant by terms like distortion, spectral
