Grazing incidence optics (GIO) is the most important compound in an x-ray detection system;it is used to concentrate the x-ray photons from outer space.A nested planar GIO for x-ray concentration is designed and developed by authors in this paper;planar segments are used as the reflection mirror instead of curved segments because of the simple process and low cost.After the complex assembling process with a special metal supporter,a final circle light spot of Φ 12 mm was obtained in the visible light testing experiment of GIO;the effective area of 1710.51 mm2@1 keV and 530 mm2@8 keV is obtained in the x-ray testing experiment with the GIO-SDD combination,which is supposed to be a concentrating detector in xray detection systems.
