摘要: 玻璃熱壓成形法為近年來逐漸受重視的玻璃光學元件製造技術,由於其擁有低成本且品質穩定的優點,因此廣為應用在球面與非球面透鏡的製作上。除此之外,利用相同概念,透過製作微結構於模仁表面,進行玻璃微熱壓轉印,以大量製造具有特殊光學功能之玻璃微結構元件,為將來光學元件製程技術的重要發展目標。 本研究嘗試使用電鑄鎳鈷合金作為模仁材料,製作結構間距250μm和500μm,結構深度皆在10μm~100μm之間的兩種菲涅爾光學微結構於模仁表面,並搭配光學玻璃型號K-PSK100之材料試片,進行玻璃微結構熱壓實驗,探討實驗參數與成形性之間的關係,並成功製作出具有初步光學效果之光學玻璃微結構透鏡。
Hot embossing of optical glass is a gradually emphasized technique for optical elements fabrication in recent years. It is generally used to manufacture spherical and aspherical lenses with the advantages of low-cost and stable quality. Besides, the same technique is applied to mass produce microstructure optical glass elements by the molds with microstructure surface. Therefore, it is an important goal in optical element fabrication. In this research, electroformed NiCo alloy was used for mold material. Then the research tried to replicate two kinds of optical structures with the pitch of 250μm and 500μm, and both the depth were 10μm~100μm. The optical glass used for microstructure hot embossing experiment was K-PSK100. Several experiment parameters and effects on the microstructure hot embossing experiments were examined and discussed.
