Title: | Rapid optical mu-printing of polymer top-lensed microlens array | Authors: | Ouyang, X Yin, ZK Wu, JS Zhou, CH Zhang, AP |
Issue Date: | 2019 | Source: | Optics express, 24 June 2019, v. 27, no. 13, p. 18376-18382 | Abstract: | Microlenses have wide applications for light beam focusing or shaping in microoptical systems. However, it remains challenging for conventional microfabrication methods to rapidly fabricate arrays of microlenses with complex profiles like lens-on-lens structures. In this paper, we present the rapid fabrication of polymer microlenses with lens-on-lens structures by using a digital optical mu-printing technology. An improved dynamic optical exposure method is developed to directly and precisely fabricate polymer top-lensed microlenses (TLMLs). Arrays of TLMLs with either elongated focal depth or two separate foci have been numerically investigated and experimentally demonstrated. | Publisher: | Optical Society of America | Journal: | Optics express | EISSN: | 1094-4087 | DOI: | 10.1364/OE.27.018376 | Rights: | © 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement (https://www.osapublishing.org/library/license_v1.cfm#VOR-OA) © 2019 Optical Society of America.
