Abstract
A device for shielding an image intensifier from electromagnetic interference which includes a hollow conductive mantle surrounding the image intensifier and over the end except for light input and output windows. It is adapted to be electrically connected to a ground reference potential for diverting electromagnetic interference to the ground reference potential, and in this capacity, functions as a Faraday cage. The mantle contains a conductive plate, preferably in the form of a sleeve, affixed within it. The conductive plate is insulated from the mantle by a layer of dielectric substance. The conductive plate is adapted to be electrically connected with an input lead for powering the image intensifier; the conductive member, the interposed dielectric substance and the mantle comprising a bypass capacitor for the input power lead.
