本文敘述光學薄膜技術，從一般日常家用的太陽眼鏡與藝術品，民生消費需求的相機鏡頭，拓展至最嚴苛的太空科技中的取像裝置，同時更因應製程需求，延伸至 IC 半導體與封裝產業。另外，透過感測器的蓬勃發展，也廣泛用於生物醫學產業與智慧車產業中各式與感測、取像中與光學有關連的器件⋯等。在短短數十年間，鍍膜的工藝技術，透過科技的演進與工業技術的精進，已發展成為各個領域製作關鍵性零組件不可或缺的關鍵技術，儼然已經成為現今所有高科技產業背後強大的支撐技術的後盾。文中也介紹儀科中心曾經開發的產品以及開發的理由。

This article gives a brief introduction of thin film technologies which can apply for the variety of goods. The application fields include the sunglasses or art decorations used in the daily life, the camera lens used in consumer devices, and extend to image capture device used in the space instrument subjected to strictly harsh environment, the optical components used in semiconductor and packaging equipment required for the precise and accurate operations. In addition, the applications of thin film technologies are also for the optical components, sensors and image devices related to the optics which are for biomedical industries and automobile industries. Within a few decades, the thin film technologies become an indispensable technology to produce the key and functional parts in all fields and an invisible but profoundly necessary backup for the high tech industries. The thin film technology continues to be advanced with the improvements of the other technologies. In this article, we report what optical components we have developed and the reasons why we have to invent.
