We describe a simple technique, based on the method of Abeles, for routine measurements of the refractive index and the thickness of transparent planar thin films. The optical and electronic hardware required to implement the technique involves only standard equipment available in most laboratories. The results obtained with this method are compared with ellipsometric measurements.
