IR Cut Filters & Dicing

Our Services

IR Cut Filters

IR Cut Filters

Our IR cut filters feature an infrared absorption layer formed by spin coating an infrared absorption liquid on an IR substrate. The high infrared absorption qualities of the infrared absorption layer offer optical characteristics equal to or greater than those of blue glass filters.



Our semiconductor dicing technology has been honed over many years and provides us with the knowledge and skills to cut a variety of materials including silicon, glass substrates (coating glass and blue glass), and quartz.



We also offer many other services, including using ROM writers to write all kinds of memory, small part taping, and assembly of parts and products.

Thank you for attending "Optical Thin Film Fair 2016"
We would like to thank the many people who attended "Optical Thin Film Fair 2016," held from Nov. 15 through Nov. 17, 2016 in the Tokyo Science Museum. Our exhibit this year was devoted to introducing "BAG filters," our 0.1 mm thin glass type absorption type filters. Over the course of the three-day event, we had the opportunity to hear questions, suggestions on applications, and much more from the many attendees. Overall, it was a great chance to reconsider how our products and machining technologies can be of use to our customers. Once again, thank you all for visiting our booth during such a busy time of the year!
