Abstract

It is difficult to quantitatively determine the surface condition of the lens mold in the lens fabrication process. In this study, we develop an automated light scattering measurement system, which enables the scattered light pattern from the lens mold to be distinguished using angle-resolved scattering with an intensity pattern matching method. It is found that various defects on the lens mold can categorize and determine their surface-specific parameters. Both the scattering angle and scattering intensity distribution is analyzed, and the scattering pattern is categorized by pattern matching for specific shapes such as fan, line, and diffraction patterns.
