Summary:UV cast-and-cure replication of micro and nano features on rolls from 60 inches wide and 4000 feet long are now common place. Customers require detail defect maps to optimize their yield and minimize their cutting costs. Luminit has implemented a high speed -in-line inspection system to monitor the defects real-time during the replication process. The results, as well as the challenges and limitation of the system will be reviewed.
