16. PS28 is an effective night vision system that mounts forward of an existing riflescope spotting scope further referred to as a scope adding night vision capabilities to daytime target acqui sition platform Advisable dayscope magnification is 1X to 12X 2 5X to 8X is optimum The sight is installed and removed with out affecting boresight permanent boresight alignment NOTE The PS 28 can be installed also forward of viewfinders of vari ous instruments to widen operating illumination range B Principle of Operation The PS28 operation is based on the principle of electron optical intensification of light The input fast catadioptric lens collects available ambient light from sources such as the moon stars and skyglow and focuses it on the image intensifier tube photocath ode The tube amplifies the light and produces the viewable im age projected by the output lens from the tube screen into the dayscope lens Thus the sight provides the capability for operator to see through the scope at night C Features The PS28 has the following important features e Available with 2 3 WPT V or 4th generation image intensi fier tube Powered by a single 123A lithium battery e Adjusts for lens focus e Automatic Brightness Control System always keeps the IIT brightness level constant even under unsteady brightness conditions Equipped with remote control WPT is a registered trademark of American Technology Network Corp 1 5
