A simple evaluation method has been developed for a metal thin layer on a sphere-like plastic microstructure, based on its light-scattering property since, according to our results, the light-scattering intensity of silver-coated microbeads depends significantly on the silver coverage. Our attempt was carried out by using a dark-field microscopy coupled with a spectrometer.
