Ellipsometric inversion problem for one nonabsorbing layer with unknown thickness and refractive index over an arbitrary substrate is discussed. The method solves an equation that depends only on the refractive index, and calculates the thickness from this refractive index. The equation for the refractive index is reduced to a fifth degree polynomial for relative dielectric constant.
