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.
Famous Trails® 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 Famous Trails® 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 Famous Trails® system, you will find that understanding the specifications of how our system measures up is sometimes difficult, especially when talking about actual use in the field. It is important to understand what is meant by terms like distortion, spectral
