In this article, a novel x-ray image intensifier is introduced. It is mainly composed of an x-ray intensifying screen and a low-light-level (L{sup 3}) image intensifier. In order to obtain a bright enough image, the spectral compatibility among three different combinations of the x-ray intensifying screen and the photocathode is analyzed. The comparison indicates that a (Zn,Cd)S:Ag screen is superior to either a CaWO{sub 4} screen or a Gd{sub 2}O{sub 2}S:Tb screen when combined with the Super S{sub 25} photocathode and spectral compatibility analysis is a useful guide when designing an optoelectronic imaging device.
