Abstract
In an optical wavelength standard, a concrete matrix embeds wavelength reference material. The concrete matrix is formed from a powdered halogenated polymer (e.g., PTFE) which is mixed with powdered wavelength reference materials, such as rare earth oxides, and the mixture is subjected to sufficient pressure to cause the particles of the halogenated polymer to coalesce into the concrete matrix.
