Fresnel zone plate and the x-ray microscope using the Fresnel zone plate

A even if it is not possible to reduce the width of the opaque zone of the outermost periphery, to provide an X-ray microscope using Fresnel zone plate and the Fresnel zone plate having a composite illumination function capable of improving the resolution. Fresnel zone plate 1 with a composite radiation features The invention relates, on the flat plate-like transparent substrate 2, arranged alternating with opaque bands 3 and zona pellucida 4 concentrically toward the radial direction from the center , a portion of a plane wave vertically irradiated on the upper surface, it is to be perpendicularly incident on the sample 6 disposed below the Fresnel zone plate 1 without being scattered, it is obtained by forming a transparent window 7. .The
