Thin film form of many solid materials with a thickness ranging from several nanometers to hundreds of microns have been extensively used in engineering systems to improve mechanical, optical, electrical and thermal functionality, including microelectronics [9], photonics [10], optical
Thickness measurements also require that a portion of the light travel through the entire film and return to the surface. If the material absorbs light, thickness measurements by optical instruments will be limited to thin, semi-opaque layers. This limitation can be circumvented by targeting measurments to a spectral region with lower absorption. For example, an organic film may strongly
