An X-ray optical device that operates in a transmission arrangement is preferable for increasing the photon flux density at a sample position of existing synchrotron radiation beamlines with as little reconstruction as possible. The study aimed to develop that new X-ray optical devise. The prototype device was designed, fabricated and the optical performances were measured. A photon flux density gain of 3.1 was achieved. The present optical device can be used to improve beamlines for experiments that do not require microfocusing such as X-ray absorption fine structure spectroscopy, powder diffraction, and small-angle scattering experiments.
