X-ray optical elements.

X-ray optics is the branch of optics which operates X-rays instead of visible light. While lenses for visible light are made of transparent materials with a refractive index substantially larger than 1, for X-rays the index of refraction is slightly smaller than unity. The principal methods to manipulate X-rays are therefore by reflection, diffraction and interference.

The basic idea is to reflect a beam of X-rays from a surface and to measure the intensity of X-rays reflected in the specular direction.

In X-ray diffraction a beam strikes a crystal and diffracts into many specific directions. The angles and intensities of the diffracted beams indicate a three-dimensional density of electrons within the crystal. X-rays produce a diffraction pattern because their wavelength is typically the same order of magnitude (0.1-10.0 nm) as the spacing between the atomic planes in the crystal.
