文摘
We report for the first time on a compact, desk-top size, laboratory-type microscopy setup, based on nitrogen gas puff target soft X-ray source, which emits radiation in ¡°water-window¡± spectral range. The microscope employs Wolter type-I objective and allows capturing magnified images of objects with 850 nm spatial resolution and exposure time as low as a few seconds. Details about the source and the microscope as well as imaging results for test and biological objects are presented and discussed.
