19 July 1996 Real-time interferometric analysis of spinning liquid films
Author Affiliations +
Optical interferometric monitoring of spin coating (optospinography) has allowed close observation of a thin liquid film temporal evolution (at 500 -2500 rpm, 100 Hz data acquisition), from which its kinematic viscosity can be determined. The data obtained from this procedure is in good agreement with known values for two oil standards, indicating that the method is valid in the range of approx. 0.4 to 150 Stokes. Advantages and limitations are discussed.
