Inline Imaging-Ellipsometer Resets Speed Barrier for Thin-Film Quality Control in Roll-to-Roll Manufacturing
Researchers at TU Wien University have unveiled an inline imaging-ellipsometer purpose-built for roll-to-roll (R2R) production, with an Allied Vision EXO250ZU3 polarized camera at its core. The system delivers real-time, full-area optical thickness measurement of functional coatings directly on moving foils, eliminating the sampling delays and blind spots that have long plagued R2R quality assurance.
