Technology / Equipment

Full support for optical products by Keihin Komaku Co., Ltd.

We maximize our optical thin-film process technology and the know-how, enable prompt offering of trial products and contribute to shortening delivery time. Besides, we have 2 factories in Japan and the second factory newly established in China in 2008, which are equipped with mass production facilities. Our consistent processes such as material processes, cleaning, evaporation coating, test, cutting, bonding and so on maintain the quality and contribute to cost reduction.
Please contact us for our free consultation/free estimates etc.

We have a variety of equipments to produce products corresponding to our customers’ needs.

Our cleaning processes have various ultrasonic cleaning equipments, and we can respond to mass production and large substrates. In addition, our evaporation coating processes have various large multilayer film vacuum evaporation equipments, where enable the high-value added process using IAD (Ion Assisted Deposition), IP (Ion Plating), SP (Sputtering) etc.
From small quantity production to mass production, we have the production systems tailored to our customers’ needs.
