Abstract
Demand for improving image quality of cameras has largely grown, especially in industrial fields such as broadcasting, on-vehicle, security, factory automation and medicine. Surface of glass lenses as a key component of cameras is formed and finished by polishing using small tools. The existing polishing technologies, however, have serious problems including an unstable material removal rate over time. In this study, we investigated mechanism of the variation in the material removal rate, specifically the low material removal rate at the beginning of polishing process. Based on the findings, we clarified that surface of polishing pad with high wettability is effective in stabilizing the removal rate.
