A method and system are disclosed for determining at least one optical characteristic of a substrate, such as a semiconductor wafer. Once the optical characteristic is determined, at least one parameter in a processing chamber may be controlled for improving the process. For example, in one embodiment, the reflectivity of one surface of the substrate may first be determined at or near ambient temperature. From this information, the reflectance and/or emittance of the wafer during high temperature processing may be accurately estimated. The emittance can be used to correct temperature measurements using a pyrometer during wafer processing. In addition to making more accurate temperature measurements, the optical characteristics of the substrate can also be used to better optimize the heating cycle.
