摘要

We developed an ink-jet printing process to fabricate microlens arrays (MLAs) by creating microwell structures based on the "coffee ring effect"to confine the lenses' materials on the substrates. After O2 and CF4 plasma treatment, the MLAs exhibited well-confined patterns with distinct ridge boundaries possessing repellent surfaces. Further, through appropriate control over the printing of the multidrops and the printhead temperature, we obtained optical microlens with different f-numbers. This fabrication method is a simple, shape-controllable, and material-saving approach compared to the traditional fabrication process.
