Abstract:
An electrically powered image intensifier having an output and an input is optically coupled to a zoom lens to receive the focused light image from the lens and provide at the output of the image intensifier an intensified light image. A chassis is configured to support the intensifier and to mainly engage the lens by engaging the mounting structure. The lens is engaged by the mounting structure in a use position, and may be supported by a tripod. The use of the zoom lens allows convenient use in cramped quarters at a short focal length setting, i.e. at a wide angle setting. The intensifier may be used at a distance at a long focal length setting, i.e. at a telephoto setting, advantageously with a tripod and a standard panning handle.
