OLUTION how well an image is rendered and displayed by a Famous Trails device A constant it can be expressed as the maximum number of lines per millimeter Ip mm that can be distinguished when a white and black striped pattern is focused on the photocathode The best resolution in most Famous Trails systems is at the center of the view with blurring towards the edges 11 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 in sinusoidal waves Nanometers nm and Micrometers mn are units of measure in the photonic spectrum

12. reasonable sum RANGE To be able to view an object from a certain distance involves the system s ability to magnify an image its resolution 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 normal image size For example a Famous Trails product made for viewing objects at a fairly close range 1x image size This makes it easy for the user to view the subject without becoming disoriented IMAGE QUALITY The best image to have is one with little distortion high definition and excellent resolution The Famous Trails device displays a green monochrome image that is clearest in the center with blurring towards the edges The human eye is able to perceive contrasts in green more easily than in other colors so this further enhances image quality With less distortion you ll see a flatter less rounded view with a higher definition Additionally the contrasts will enable you to perceive dark objects against darker backgrounds and the increased resolution will allow you to see identifying details clearly ins
13. rts 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 efficiency in the near infrared bandwidth PHOSPHOR SCREEN renders a visible green image by exhibiting fluorescence when impinged by the electron flow in the intensifier tube The human eye picks up on contrasts in green more easily than other colors The phosphor screen is positioned at the back of the intensifier tube PHOTONIC SPECTRUM the span of electromagnetic energy ranging from 0 1mm x ray to 1 000mm far infrared The visible range within this span is from 400 to 750nm PHOTOCATHODE component that changes light photon energy into electrons electrical energy which in turn move with increasing speed in the intensifier tube The objective lenses point light on the photoelectric surface of the photocathode which is excited and passes electrons through the intensifier tube PHOTOSENSITIVITY the measure of the photoelectric current from the photocathode per the input light flux from a tungsten lamp It is expressed in microamperes per lumen and indicates the photocathode s sensitivity to light RES
14. tead of mere shapes Buying a Famous Trails Product Before purchasing a Famous Trails product think about how you want to use it and select the device that best matches that use A scope with moderate gain and a short lens with a 1x magnification would be appropriate for populated areas such as a housing complex If you are using the scope in a forest with little light increased gain would enable you to see more clearly and a longer lens would allow for viewing at a greater distance Inside a building or warehouse a user would want to use an infrared illuminator and would probably not need long range capabilities There are other considerations to be made before choosing your Famous Trails product 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 their users but prices can range from 199 to 10 000 Think about how often and in what way you will be using your product and thus how much you want to spend A scope or monocular for 2 500 would be a fantastic piece of equipment to own but you could also p
