... reflectance, excellent correlation is found between the measured peak reflectance and that calculated from the depth of the more easily measured secondary reflectance minima. Errors in film thickness or significant interface absorption arising from impurity segregation, surface plasmon excitation, or other...

... Approximate closed-form expressions are developed for predicting the effect of volume and interface absorption in thin films on the performance of quarterwave multilayer coatings. For highly reflecting coatings on dielectric substrates the volume absorption expressions are equivalent to those...

... measured the combined absorption due to the two film interfaces. It will be shown that, in some cases, it is possible to distinguish between air-film interface absorption and film-substrate interface absorption and determine the magnitude of each. Data will be presented for 2.9 and 2.7 µm for films made...
