在本文中,我们展示了一个简单的微球透镜阵列(MBLA)的制造方法,使用按需滴(DOD)的液滴印刷技术和液体模具。利用疏水表面上的微球液滴阵列作为液模制备MBLA。微球液滴与基底之间的粘附力归因于微球液滴的Wenzel状态,而具有低位置误差的复制过程归因于微球液滴与基底之间的粘附力和微球液滴与聚二甲基硅氧烷(PDMS)液体的高粘度。制备了接触角为120°和150°的微球透镜,并讨论了制备过程中的一些重要细节。光学性能和扫描电子显微镜(SEM)数据表明,MBLs具有高质量的表面形貌和良好的光学性能。
In this paper, we demonstrated a simple micro-ball lens array (MBLA) fabrication method using a drop-on-demand (DOD) droplet printing technique and liquid mold. The micro-ball droplet array on the hydrophobic surface is used as the liquid mold to fabricate the MBLA. The ultrahigh adhesion force between the micro-ball droplet and the substrate is ascribed to the Wenzel state of the micro-ball droplet, while the replication process with low position error is attributed to the ultrahigh adhesion force between the micro-ball droplet and the substrate and the high viscosity of the micro-ball droplet and polydimethylsiloxane (PDMS) liquid. The micro-ball lenses (MBLs) with a contact angle of 120° and 150° were fabricated and the important fabrication details were discussed. The optical performance and scanning electron microscope (SEM) data of the MBLs showed that the MBLs had high quality surface morphology and good optical performance.
