Owners Manual Thank you for purchasing this night vision device brought to you by Famous Trails. We hope it will bring you many years of viewing pleasure. “ Starlight” or “ Night Vision” devices work by amplifying ambient light thousands of times to create a visible electronic image. Even starlight or partial moonlight can often provide enough light to allow for viewing. However, please remember that your starlight device is a sophisticated opto-electronic instrument and should be u

F AMOUS TRAILS NIGHT VISION PRODUCTS 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 fie

response, optical speed, gain and more. It is also important to note that each product was tested with consistent reliable methods to insure the valid comparison of specifications. This is an area where comparison becomes especially difficult, as there are a great number of equipment manufacturers but little published specs comparing products from various companies. The bottom line is that even with technical specs it is hard to tell if the item will perform the way you need it to. ®

how much light is available, and the gain of the product. A long, powerful lens will increase magnification, but as mentioned above will not transfer light well. In conditions with less light, more gain is required to view objects farther away so using a high-speed lens with less magnification will allow more light to be captured and will increase the product’s range abilities. Generally most users don’t need long-range capabilities in their products and are satisfied with 1x to 3x the n

ERGONOMICS—If you will be viewing for a long period of time, a lighter product will be more comfortable. Also, where you wish to carry your device will make a difference when deciding on what size to purchase. PRACTICALITY—If you will be using your system on camping trips and other places where electricity is unavailable, make sure the battery corresponding to that system is easily available for purchase. PRICE—Famous Trails specializes in creating affordable prod- ucts for

DIOPTER ADJUSTMENT—an adjustment of a device to a user’s eyesight. The range for adjustment is usually plus or minus 4 Diopters. DISTORTION—any variation of the display from the accurate reproduction of an image. EYE RELIEF—the required distance between a user’s eye and the lens of a device to enable a full view of the object. Usually a longer eye relief will afford a more comfortable view, especially for people who wear glasses. FIELD OF VIEW—the measured view a user see

• Generation II—contains a microchannel plate for increased gain. Generation II devices were designed for more difficult viewing situations and are mostly used by military or scientific personnel. • Generation III—contains a gallium arsenide photocathode and a microchannel plate. Generation III devices are designed for applications such as special military operations due to their high light sensitivity and clear viewing in the darkest conditions. IMAGE INTENSIFIER or INTE

OCULAR—see optics OPTICS—the collective term for all optical parts of a Famous Trails system which includes the objective lens and the ocular. • The ocular increases projection size of the image. • The objective lens gathers ambient light, focusing it onto the image intensifier. Can also provide an increase in size of image view. Short focal lengths (image size is 5x or less) and high-speeds (f2 or faster) are found on the best objective lenses. They are coated for the best eff

SCOPE—a Famous Trails device with one ocular system. SPECTRAL RESPONSE—the numeric range of wavelengths in the phototonic spectrum amplifiable by a Famous Trails device. While the human eye can see from 400nm to 750nm, a Famous Trails system can pick up and amplify wavelengths up to 900nm and project an image of the viewed object onto its phosphor screen. SPECTRUM—see phototonic spectrum WAVELENGTH—the distance covered by one cycle of a wave. Electromagnetic energy is transmitted i
