4) Intensifier Protection – In order to assure long-life and high sensitivity performance, do not use during daytime or bright ambient conditions. Do not look at the sun or extremely bright objects. Do not look at bright objects for long periods of time as this may cause the intensifier tube to develop insensitive areas. 5) Accessories - Use only accessories and attachments recommended by Electrophysics. 6) Water and Moisture – These products are NOT waterproof. They are

1.4 How Image Intensifiers Work Image intensifiers are predominant in night vision applications due to their ability to amplify low-light scenes at night, making them visible to the human eye and commercial cameras and camcorders. Unlike thermal images, image intensifiers can be used to read vehicle license tags and registration markings on boats and aircraft, as well as to recognize faces, which can be entered as evidence in criminal prosecutions. The sequence to image formation in

photocathode. This dim light consists of energy in both the visible and near-infrared portions of the electromagnetic spectrum. 2. When the light impinges on the photocathode (the light sensitive portion of the image intensifier) electrons are emitted with amplitude determined by the photocathode's spectral responsivity and the amount of light energy. Because of the image intensifier's internal electrical field, these electrons are accelerated toward the microchannel plate assembly, t

1.5 Evolution of Image Intensifiers The image intensifier tube has evolved substantially over the past few decades. This evolution is described by different generations (“Gen”) of technology as follows: Gen 1 – These are the first so-called night-vision devices and were introduced in the early 1960s and first fielded in Vietnam. These devices utilized a multi-alkali S-25 photocathode having a spectral response extending from visible to about 850nm. In order to have sufficient sensit

a result, surveillance operatives that have been trained with daylight imaging equipment may insert an optimally-configured night vision module into the daylight lens/camera system and operate the equipment in virtually the identical fashion at night as compared to the day. • Reduced Technology Obsolescence: Because of the AstroScope’s modular design, this night vision system is never obsolete. As new cameras are introduced, new adapters can be designed that deliver optimal night-time
