Patent ID: 7623627

Claim:
An X-ray analysis apparatus, comprising: a radiation source for irradiating an arbitrary irradiation point located on a sample with a radiation beam; an X-ray detector for detecting a characteristic X-ray and a scattered X-ray radiated from the sample and outputting a signal containing energy information on the characteristic X-ray and the scattered X-ray; an illumination mechanism for emitting an illumination light to the sample to illuminate the sample; and an observation mechanism for obtaining an illumination image of the sample, which is illuminated with the illumination light, as image data, wherein the illumination mechanism includes a concave-convex illumination section in which an optical axis of the illumination light at a time of the illuminating is set toward the irradiation point in the same direction as a direction linking the irradiation point with the X-ray detector at a time of the detecting.
