We have developed an experimental light-scattering method to obtain information about particles with low polydispersities in size on flat substrates. It is based on the analysis of the visibility factor of the lobes in the light scattering patterns obtained from flat metallic substrates seeded with the particles. The visibility factor of a pattern is obtained for different minima. The solution of the scattering problem may be provided by a theoretical model, and analytical expressions for the visibility are derived. This relation between visibility and polydispersity is experimentally tested, and it is shown how the origin of the loss of visibility may be exploited to characterize the polydispersity.
