Image of FIG. 1.
FIG. 1.

Photograph of a bubble CRL formed inside a capillary of diameter. These bubbles form spherical unit lenses whose diameter is and minimum wall thickness is approximately .

Image of FIG. 2.
FIG. 2.

The simple x-ray microscope whose magnification is the ratio of the image, , over the object distance, .

Image of FIG. 3.
FIG. 3.

(a) and (b) A comparison of the FOVs: (a) A of 2000-grid mesh (grid period is ) using synchrotron source. (b) A of a 400-grid mesh using an x-ray tube. Since (a) is so much smaller than (b), we have increased (a)’s size for visual clarity.

Image of FIG. 4.
FIG. 4.

A line profile across one period of the grid image at the objective plane. The grid aperture was optically measured to be and closely matches that the measured value of . Resolution of the edge of the grid aperture is .

Image of FIG. 5.
FIG. 5.

X-ray image of the spinal column of Paracheirodon Innesi (neon tetra aquarium fish) obtained using a bubble CRL and an unfiltered x-ray tube.
