✦ Synopsis

A description is given of an ellipsometer, automated by means of computersteered stepping motors. Conversion of analyzer and polarizer readings into thickness and refractive index is done by a graphic procedure on (A,$)-+ (n,d) conversion plots. The method is tested by means of Langmuir-Blodgett monolayers of barium stearate. Adsorption of fibrinogen and albumin onto hydrophilic and hydrophobic chromium surfaces, the interaction of fibrinogen with anti-fibrinogen, and the interaction of albumin with anti-albumin are shown as illustrations of the technique.
