Description
We developed a micro-XRF instrument with a hybrid X-ray optic in order to obtain an intense micro X-ray beam in laboratory. The hybrid X-ray optic consists of the polycapillary X-ray lens and the Zr pinhole. The Zr pinhole, which was inserted between the X-ray tube and the polycapillary X-ray lens, was useful for reducing the spot size of micro X-ray beam. In addition, the divergence of micro X-ray beam was reduced by applying the Zr pinhole with a diameter of 400 μm. Moreover, SB ratio of X-ray fluorescence was also improved by using the Zr pinhole.
