Paper Abstract

Optical interferometric monitoring during spin coating of fluid coatings has allowed close observation of their temporal evolution. When the fluids are non-volatile, kinematic viscosity data can be determined using a simple analytical model. Validity of the method was tested with a standard nominal kinematic viscosity v equals 37 +/- 1 cS for which the optospinography method, combined with Abbe refractometry, provided v equals 36.1 +/- 0.1 vS. This is an indication that we now have available an absolute, contactless optical viscometry method for thin fluid films in small samples.
