Abstract
The X-ray detection apparatus is equipped with an X-ray irradiation unit, an X-ray detector, and a movable collimator having a plurality of apertures. The collimator is provided with a window unit through which light passes, and the apertures and the window unit are aligned in one direction. The collimator moves in the direction so as to change the diameter of an aperture for narrowing X-rays from the X-ray irradiation unit to be used for irradiation of a sample and move to a position to allow an imaging unit to photograph a sample through the window unit. It becomes possible to photograph a sample even in a state where the X-ray irradiation unit, the X-ray detector and the collimator are positioned proximally to each other.
