<p>The inventive X-ray microscope comprises an extended X-ray source, a unit for placing a studied object (3), a recording unit and an X-ray capillary lens disposed therebetween. The channels of said lens are divergent in the direction of the recording unit. The unit for placing the studied object is disposed between the extended X-ray source and the smallest end of the X-ray capillary lens. The inventive device is characterised in that the walls of the channels (14, 16) for transmitting radiation are coated with or made of a material which absorbs or scatters X-ray radiation, and are shaped in the form of the lateral surface of a frustum of cone or pyramid, or of a truncated cylinder or prism. Said material excludes the effect of total external reflection. The straightness of the longitudinal axes of the channels makes it possible to use said channels as collimators. The resolution capability totally depends on technological capabilities to reduce the input size of the channels. The use of the extended X-ray source makes it possible to significantly reduce the time of exposure and the power of an X-ray tube.</p> |
