Our facility houses not only our manufacturing, but our corporate offices, design engineers, as well as a clean room, sophisticated coaters, and measurement instruments.

EOC's filter chip can be applied to optical telecom applications as well as those within the non-telecom industry. Within the telecom industry, they are classified as narrowband and broadband.
EOC also works with the customers to customize our products for their specific applications, such as Coated WDM on pigtail for hi isolation applications, IR-cut filters for Digital Still Cameras(DSC) and Compact Camera Module(CCM) applications, and R/G/B filters for Digital Lighting Processing(DLP) projectors, to name a few examples.


Determining optical fiter specifications, for telecom as well as non-telecom applications, is less than straightforward and we at EOC understand that clearly. Our experience in the coating industry over the past years has led us to various specifications meeting a broard range of customer needs. While recognizing that the specifications we provided here may not meet you specific needs, they may help you in determining your particular specifications. Finally, our experienced engineering design team is here to work with you and your customized specification.
