Abstract
Collimator unit between X-ray tube and sample includes a plurality of collimator plates and displacement mechanisms, which move the collimator plates in interlocked fashion so as to locate the centers of through-holes on a line connecting X-ray focal point to an arbitrary point on the sample W, thereby suppressing the shading of X-rays due to the axis of the through-holes of the collimator unit becoming diagonal to the line connecting the X-ray focal point and the point on the sample.
