A technique for measuring the refractive-index dispersion in light-guiding thin films by means of the prism-coupling method is reported. A collimated polychromatic light beam is employed, and the wavelength dependence of synchronous angles is determined spectroscopically. A representative experiment performed on an amorphous specimen reveals its usefulness for investigating the detailed dispersion characteristics of thin films with accuracies better than 0.001.
