報告題目(Title):

Precision glass molding technology for micro/nano structures

微納陣列結構精密模壓成形技術


報告摘要 (Abstract):

       微納陣列是由單元特征尺寸為數百納米到數十微米的三維結構陣列或透鏡陣列組成的玻璃光學元件,單位面積内微結構單元數量巨大,具有特殊的幾何光學特性,主要用于高精度三維定位用微納結構陣列與高清晰三維成像。本報告重點介紹光學微納陣列的高效精密模壓制造技術,以單元極小化、面積超大化、精度極限化和形狀複雜化為光學微納陣列制造技術目标。以新型模具材料制備,超精密微納切削加工和精密模壓成形為技術手段,重點介紹微模具材料制備方法,微納模具超精密切削制造及在位測量技術、玻璃模壓制造技術及相應的表征評價方法。通過理論與技術創新,實現大面積高密度玻璃光學微納陣列的高效超精密跨尺度制造。


The micro/nano structures belong to glass optical components and composed of large quantity of three-dimensional structure arrays or lens arrays with cell feature size of several hundreds of nanometers to several tens of micrometers, thus have special geometric optical characteristics and mainly used for high precision three-dimensional positioning and high-definition three-dimensional imaging. This report focuses on the high-efficiency precision glass molding technology of optical micro/nano structures with the manufacturing goals of minimal cell feature size, extremely large area, highest precision and complex shape. The new mold materials fabrication, ultra-precision micro/nano cutting and precision press forming are the technical means to achieve these goals. Thus in this report, the fabrication methods of mold materials, ultra-precision manufacturing of micro/nano mold by cutting, on-machine measurement technology, glass molding technology and the corresponding characterization evaluation methods would be introduced in detail. Through theoretical and technological innovations, the high-efficiency, ultra-precision and cross-scale manufacturing of large-area and high-quantity-density glass optical micro/nano structures could be realized.
