Fluorescent X-ray device

摘要

A flourescent x-ray device for irradiating x-rays to a sample so that flourescent x-rays emitted from the sample can be detected is described. A stationary fixed collecting plate is used instead of the movable reflecting plate employed in the prior art. The reflecting plate possesses the characteristics of being transmissive to x-rays and being reflective to visible light so that an image of the sample can be viewed by an observer and the sample can be irradiated with x-rays passing through the plate. The invention permits a remarkable decrease in manufacturing cost. Moreover, the device can be operated in a stable condition with high accuracy for a long time.
