X-ray shielding mechanism for off-axis X-rays

摘要

An X-ray shielding mechanism to block off-axis X-rays for example, in an X-ray analytical instrument such as a fluorescent X-ray spectroscope is provided. X-rays are guided on-axis by elongated glass guide tubes and outer elongated metallic protective pipes are spatially positioned on the exterior of the glass guide tubes to block off-axis X-rays.
