Paper Abstract

We present a novel method for determining both the thickness and optical constants of weakly absorbing thin film on nearly transparent substrate through analysis of transmittances measured at various incident angles with the coherent lights. We demonstrate this method for polymer thin film. The refractive indices and extinction coefficients of poly (tetracyanoethylene-carbazole) at two different wavelengths of 1064nm and 532 nm were determined for the first time to our knowledge. It is found that a thickness of a few hundred nanometers can be easily measured and this method offers simplicity as well as in situ measurement.
