This paper documents the evolution of a project to make and optically characterize cermet films. Cermet films of gold and alumina were sputter deposited onto silicon substrates. The resulting film consisted of nano-sized gold grains embedded in a matrix of alumina. The films were designed to absorb visible radiation and reflect IR radiation in the space environment. Ex-situ and in-situ ellipsometry (0.2-30μm) were used to characterize the film optical constants. Reflectance data (0.2-30μm) were used to verify film performance.
