PMMA微透镜阵列的非接触式热压印制作技术
Fabrication of PMMA Microlens Array with Contactless Hot-embossing Technology
摘要
Abstract
This paper presents a novel method for fabrication of polymethyl methacrylate(PMMA) microlens array by contactless hot-embossing with through-holes stainless molds.An array of plano convex microlenses was formed due to the surface tension of polymer above the glass transition temperature.The curvature and height was controlled by adjusting the temperature,pressure and time duration.In addition,the principle of contactless hot-embossing by finite element analysis was studied,and the model was built by Ansys.An independently developed hot-embossing equipment was used to fabricate microlens arrays on PMMA sheet.And the influences of technological parameters such as temperature and pressure were analyzed.Finally,their optical performances were tested.The experimental results show that microlens array has good surface features and high position precision.The contactless hot-embossing technology is process simplified,one-step forming,independent on surface quality of mold.关键词
