Electron Diffraction

true nanometer accuracy for sample rotation

Electron diffraction is used to perform nano-crystallography of various materials and is of high relevance especially in the fields of chemical, pharmaceutical, and advanced materials research. The advantage of electron diffraction compared to X-ray crystallography is that electrons are less penetrating and therefore scatter more intensely. This allows the analysis of very thin layer samples which offer better availability than large crystals, and provide strong diffraction patterns in a short time. Electron diffraction analysis is usually performed as one of multiple techniques in electron microscopes, but due to the rising relevance, dedicated diffractometer concepts have emerged.

To achieve the highest resolution, the sample has to be positioned with the highest accuracy in vacuum conditions. Motion errors during the rotation of the sample, most importantly the radial runout, have to be minimized.
