materials needed for optical science research and industrial applications. The interaction of light with matter is different at different wavelengths and the techniques to measure the optical properties differ based on the spectral region of interest. This document addresses the techniques
The Materials Measurement Science Division is actively developing new Standard Reference Materials (SRMs) for various materials measurement techniques. For reference, we also list SRM products that have been discontinued.
Scientists from NIST and other institutions have created the first neutron “Airy beam,” which has unusual capabilities that ordinary neutron beams do not. This achievement could enhance neutron-based techniques for investigating the properties of materials that are difficult to explore by other means. For example, the beams can probe characteristics of molecules such as chirality, which is ...
