Abstract

A window for electromagnetic interference shielded enclosures has a shielding screen system with two grids having dimensionally different mesh patterns to overcome optical interference and distraction resulting from the moire effect. The screens are supported in spaced, angularly offset positions on a continuous frame providing electrical continuity between the shielding system and the shielding layer of a surrounding wall.
