About

Hejuan Chen has made pioneering contributions to the field of micro-optics fabrication, with a particular focus on developing innovative, cost-effective methods for creating microlens arrays (MLAs). Her key research areas include droplet-based manufacturing, polymer replication techniques, and curved optical component engineering. Chen’s most notable work, "Fabrication of curved microlens array using a drop-on-demand droplet generator and polydimethylsiloxane replica mold" (2014, 13 citations), introduced a groundbreaking approach that combines a drop-on-demand (DOD) droplet generator with PDMS replica molding to produce curved MLAs. This method significantly simplified the fabrication process by first creating planar MLAs using the DOD system, then transferring them onto curved substrates—a technique that offers enhanced flexibility and reduced costs compared to traditional lithography-based methods. Her work has been instrumental in advancing applications in imaging systems, optical sensors, and light-field cameras. Chen’s research demonstrates exceptional ingenuity in merging droplet microfluidics with soft lithography, establishing her as a key innovator in scalable, high-precision optical manufacturing. Her contributions continue to inspire new directions in affordable micro-optics production.
