In this study, Raman scattering signals from molecules in a thin lubricant film were measured by using a newly developed tribotester with the Ottoattenuated total reflection (ATR) configuration. This system employs a point contact between a transparent dove prism (N-SF11) and an aluminum ball. From the electric field enhancement effect based on the Otto-ATR configuration, a high sensitivity measurement of Raman scattering signals was realized under shearing of thin lubricant films.
