Double optical monitoring of dip coating with a time-varying refractive index
(2006) [Journal article]A brief overview of optical monitoring for vacuum and wet-bench film-deposition processes is presented. Interferometric and polarimetric measurements are combined with regard to simultaneous monitoring of refractive index ... -
Envelope and waveguide methods : a comparative study of PbF2 and CeO2 birefringent films
(1994) [Journal article]We have characterized low-birefringence, PbF2 coatings to permit, first, agreement between envelope and prism-coupler waveguide methods under the standard isotropic assumption. In essentially the same measurement conditions, ... -
FECO-based observations of birefringence at normal incidence in optical coatings
(1985) [Journal article]Resumo não disponível -
Generalized Abèles relations for an anisotropic thin film with an arbitrary dielectric tensor : comments
(1998) [Journal article]The Cojocaru generalization of the 2 3 2 extended Jones matrix method, placed in a wider context of previous approaches to anisotropic optical thin films, is analyzed from a complementary perspective. This, contrary to ... -
Interferometric monitoring of dip coating
(2004) [Journal article]Dip-coated films, which are widely used in the coating industry, are usually measured by capacitive methods with micrometric precision. For the first time to our knowledge, we have applied an interferometric determination ... -
Simple polarimetric approach to direct measurement of the near-surface refractive index in graded-index films
(2003) [Journal article]In the standardM-line method for the characterization of graded-index films, an analytical curve is fitted to the waveguide mode measurements and extrapolated to provide the refractive index in the zero-depth limit. Here ...
