Abstract
Variable angle ellipsometry has been used to study laterally homogeneo us, interfacial structures whose index of refraction varies only in th e normal direction. A polyimide film (almost-equal-to 1.4 mum thick) w as studied on glass and the thickness and the indices of anisotropy n( perpendicular-to) and n(parallel-to) perpendicular and parallel to the lateral plane determined with high precision. Better fits to experime ntal data were obtained by assuming an additional thin layer, with dif ferent film parameters, at the polymer/substrate interface.
