Microlens arrays are gaining a significant amount of attention due to the growing demand for miniaturization of optoelectronics.
.
Microlens arrays have become a crucial micro-optics device extensively used in compact imaging, optical communication, sensing, and many others. Optically smooth microlens array is fabricated by an oscillation assisted 3D printing method.
.
Owing to the mechanical oscillation applied on the projection lens, jagged surface induced by the gaps between discrete pixels is successfully eliminated to render a low surface roughness of 1 nm, which endows the printed microlenses with high resolving power.
.
Usually, the microlens arrays comprise several micron-sized lenses possessing greater uniformity and optical surface smoothness, which increases the need for machining accuracy. Regardless of the remarkable progress made in manufacturing methods during recent decades, certain restrictions, such as high process complexity, insufficient fabrication flexibility, high time consumption, and difficulty in consistency control for the […]
