Abstract
An image intensifier having a CsI phosphor input screen. The input screen comprises a substrate of aluminum, a plurality of small mosaic blocks secured on the substrate, a plurality of grooves intervening between adjacent blocks, a plurality of metallic protrusions formed on the grooves, a plurality of phosphor blocks grown on the mosaic blocks and optically isolated from each other by the protrusions and a photocathode deposited on the phosphor blocks. The metallic protrusions cause a phosphor layer when deposited on the mosaic blocks to divide without cracking into the plurality of phosphor blocks. The upper surface of the divided layer is even, permitting the photocathode film to be deposited thereon.
