In the European Joint Research Project "Multidimensional reflectometry for industry", a new gloss scale has been developed with the aim to represent different levels of gloss, hue, roughness and refractive indices. In this paper, the surfaces of six selected samples have been thoroughly investigated using various measuring techniques in order to verify the outcome of the novel manufacturing processes in terms of distinct levels as well as types of surface roughness. The aim of the evaluation was to capture surface structures in different wavelength intervals utilizing a confocal microscope, a coherence scanning interferometer and an atomic force microscope. Also, PSD functions calculated from the measurements have been used to determine suitability of techniques for different roughness scales. Measurements show the expected surface characteristics as well as different rms roughness values intimately connected to the perceived glossiness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
