Development of roll press UV imprint process for replication of micro lens array on the large and thin quartz substrate

In this study, micro lens arrays (MLAs) fabrication process was carried out using flexible replica mold and an original roll press UV imprint system. We successfully demonstrated MLAs fabrication process with high throughput. The lens patterns of 30 × 100 mm

in area replicated by two photo-curable resins were formed on the quartz substrate of 0.15 mm in thickness. This fabrication process is applicable for MLAs fabrication of next generation optical devices.
