Abstract (en)

[origin: EP0554145A1] The invention relates to image intensifier tubes of the proximity focusing type, in which it relates particularly to the positioning of a primary screen (19) with respect to a microchannel wafer (7). An image intensifier tube according to the invention includes a sealed enclosure (2) containing a primary screen (19) and a microchannel wafer (7). The microchannel wafer (7) is fixed to the body (2) of the enclosure. According to one characteristic of the invention, the primary screen (19) is fixed to the wafer (7), from which it is kept separated with the aid of at least one insulating wedge (25, 25a). This results in greater accuracy and greater uniformity of the spacing between the primary screen (19) and the microchannel wafer (7). <IMAGE>
