title: Manual ellipsometry made semiautomatic.
abstract: A simple, inexpensive mechanical device is described that was designed to provide more effective data acquisition and to fit onto an already existing polarizer wheel drive mechanism of a commercially available, manual ellipsometer. A gas/metal adsorption experiment is used to illustrate typical results. Use procedures are detailed.
