Abstract:
1. An X-ray detection apparatus comprising: an X-ray irradiation unit; a sample support unit structured to support a sample to be irradiated with X-rays from the X-ray irradiation unit; an X-ray detector structured to detect X-rays generated from the sample; an imaging unit structured to obtain an optical image of the sample supported by the sample support unit by receiving light which is reflected from the sample and is not coaxial with X-rays; and a collimator which includes a plurality of apertures having different sizes and a window unit that light used for obtaining an optical image of the sample can pass through, wherein the collimator moves to change an aperture that X-rays pass through and moves to shift the window unit to a position that allows the imaging unit to obtain an optical image of the sample through the window unit.
