Abstract

A photoelastic modulation (PEM) ellipsometry is employed to study a water adsorption on SUS 310 surface in air as a function of relative humidity change. A natural evaporation type humidity generation method and a divided-flow type humidity generator is used to control the humidity in a chamber in room temperature condition. Detected signal shows strong ties to room temperature fluctuations and drift of optical properties of ellipsometric components including light source. Under even such a rough environment, adsorption occured and optical response is detected as relative humidity changes.
