A rapid two-photon fabrication of tube array using an annular Fresnel lens

Opt Express. 2014 Feb 24;22(4):3983-90. doi: 10.1364/OE.22.003983.

Abstract

A rapid method of fabricating microscopic tubular structures via two-photon polymerization is presented. Novel Fresnel lens is designed and applied to modulate the light field into a uniform ring pattern with controllable diameters. Comparing with the conventional holographic processing method, Fresnel lens shows higher uniformity and better flexibility, while easier to generate. This versatile method provides a powerful solution to produce tube structure array within several seconds.
