Design and Fabrication of Wafer-Level Microlens Array

Wafer-level microlens arrays have very high dimensional accuracy requirements for the profiles and positioning of the lens. To meet these requirements, the dense microlens array mold was fabricated on an ultraprecise machine (350FG, Moore Nanotechnology, Swanzey, NH, USA) with five-axis servo motion.

Design and fabrication of a freeform microlens array for a ...

In this research, a unique freeform microlens array was designed and fabricated for a compact compound-eye camera to achieve a large field of view. This microlens array has a field of view of 48°×48°, with a thickness of only 1.6 mm. The freeform microlens array resides on a flat substrate, and thus can be directly mounted to a commercial 2D image sensor.
