ABSTRACT:
An image intensifier apparatus which comprises an image intensifier for converting incoming radiation into light rays on an input fluorescent screen, further converting said light rays into electron beams on a photocathode, focusing said light rays by an electron lens system and converting said focused light rays into the visible form by an output screen; and a housing which receives the image intensifier and whose inner side wall is fitted with a radiation leakage-preventing layer and first magnetism shielding layer, and wherein second magnetism-shielding layer having a high radiation permeability is formed on any of those portions of the image intensifier apparatus into which radiation is carried.
