| Research Abstract |
A soft-X-ray microscope is expected as a novel tool to observe a high definition image of a living tissue with a spatial resolution better than 100 nm. In this study, we propose innovative solutions for high magnification soft X-ray microscopy, based on two-stage imaging optics for focal length reduction. Novel optics consisted of aspherical mirrors allow one to enhance a magnification of a laboratory based soft X-ray microscope over 1000x, where movies with diffraction limited resolution can be observed with an X-ray CCD. The design example having a numerical aperture of 0. 25 was successfully demonstrated both a high magnification and a large misalignment tolerance.
