Paper Abstract

The design and performance of a stepping-motor driven self-nulling ellipsometer are described in detail. Three levels of instrumentation are discussed: (i) the basic instrument which has been in use in our laboratory for over ten years, (ii) the addition of a ministepping drive to provide increased resolution, and (iii) the addition of quadrature Faraday modulators to provide increased speed. It is concluded that developments in technology have made this type of instrument an inexpensive alternative to the conventional manual ellipsometer.
