3-D Printed Optically Smooth Microlens Array

Caption

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.
