Abstract
With emergence of focusing X-ray optics many configurations of X-ray microscope have been developed. In this paper we report on a laboratory X-ray microscope based on refractive X-ray optics and microfocus laboratory source. In our experimental setup we use parabolic Compound Refractive X-ray Lens (CRL) made of beryllium and capillary spherical CRL made of epoxy. A copper 2000 mesh grid with 13 μm period and the width of the wire of about 4-5 μm has been clearly resolved with good enough contrast in transmission full-field X-ray microscopy mode. The advantages of the two-lens design have been shown experimentally for both transmission full-field and scanning X-ray microscopes. The discussion of the optimal distances between optical elements in the X-ray microscope is presented.
