Development of In-Process Evaluation for Microlens Mold Using Angle Resolved Scattering System

Abstract:

If the surface of a lens injection mold contains defects, the conditions of its surface coating worsen with each injection in the lens production process. Hence, an on-machine quantitative evaluation method is required for the lens mold surface. With the aim of characterizing the mold surface texture in this study, we have developed an automated light-scattering measurement system that enables 3D detection of scattered light in various directions due to the flaws and roughness of the mold surface.
