Claim:
An X-ray converter comprising: a light-proof housing, one of whose walls is X-ray transparent, and the following units fastened one after another behind this wall: an X-ray-to-optical converter of the X-radiation into visible light, a filter of residual X-radiation, an unit of objective lenses, each of which contains at least two one by one installed lenses for focusing a part of the light flux on the corresponding optoelectronic converter, and a photodetector containing at least two optoelectronic converters having partly overlapping fields of view and separated electrical outputs for connection to a system for fragmentary video signals processing and their “sewing together” into an integral output video signal, characterized in that the light-proof housing is equipped with an additional light-opaque and X-ray-opaque partition that has through-holes, whose number and placement correspond to the number and placement of objective lenses and optoelectronic converters, and is rigidly fastened within said housing practically parallel to the X-ray-to-optical converter, the filter of residual X-radiation formed as washers that are made from an X-ray opaque light-transparent material and rigidly fastened within said through-holes of the additional partition, said additional partition is equipped with blinds, whose number and placement correspond to the number and placement of objective lenses and optoelectronic converters; these blinds are installed on such side of this partition that is opposite to said X-ray-to-optical converter, and length A of each blind and distance D from the front (following the pass of X-rays) surface of said X-ray-to-optical converter to the plane of front (following the pass of light) end faces of objective lenses are related by the ratio A/D=(0.50-0.95).
