Microlens Array Fabrication Method Reduces Device Costs
WUHAN, China, Oct. 4, 2022 — Though aspheric microlens arrays (AMLAs) play an important role in advanced optical sensing, communications, imaging, and other industrial and biomedical applications, the fabrication of the elements remains a challenge. Even as MLAs stepped into diverse emerging applications, including AR/VR display and beam shaping, it is difficult using traditional MLA fabrication approaches, such as the hot reflow, ink-jet, and self-assembly, to fabricate AMLAs directly with a desired arrangement and
