X-Ray Optics
X-Ray Optics is a scholarly work, published in 1947 in ''Nature''. The main subjects of the publication include radiography, optics, spectroscopy, physics, X-ray, scattering, refraction, and X-ray optics. Although optical reflexion and refraction of X-rays have been known for more than twenty years, they have so far found only one significant, although very important, application, namely, the spectroscopy of X-rays by means of optical gratings.
