A POLYION-1M automated setup for production of nanodimensional coatings by the polyelectrolyte self-assembly method is described. The design, the scheme of connection with a computer, and software of the setup are described. The results of comparison of the parameters of the setup developed and its foreign analog are analyzed. Nanodimensional films with a varied number of layers on silicon substrates were produced. The refractive index and thickness of films were determined by the ellipsometry technique.
