X-ray condenser and x-ray apparatus

摘要

An X-ray condenser for condensing X-rays radiated from an X-ray source to a very small condensing spot is disclosed. X-rays from the X-ray source are formed to a parallel X-ray beam by a parallel type parabolic reflection mirror. The parallel X-ray beam is made monochromatic by an analyzing crystal and condensed to the condensing spot by a zone plate. The zone plate is constructed by alternately arranging a plurality of X-ray transmitting bands and a plurality of X-ray shielding bands and can condense the parallel X-ray beam to a very small focus point.
