The effect of diffusion of silver through Se thin films, on the visibility of two and multiple beam interference fringes has been studied. For thickness measurements, Al has been found to be a suitable overcoating metallic layer as it does not diffuse through Se. The thickness was measured by multiple beam fringes at reflection.

In the present work a new graphical method is described to represent the resultant of the multiply reflected waves from coating systems consisting of single and double layers on metallic substrate, taking into account the optical phase properties of the films.
