A global contact lens manufacturer needed to detect surface defects and occlusions in transparent contact lens molds, a problem that defeated conventional machine vision because the molds are translucent. Standard imaging techniques could not reliably distinguish defects from normal material properties.

Good Automation developed a novel optical inspection system using angle-of-attack illumination, refraction analysis, and light scatter techniques. The system went through multiple generations of architecture refinement, was built into a production-ready enclosure with emissions compliance, and operators were trained on-site.
