The multilayer thin film filter is produced through the integration of technologies such as the cold light mirror for LCD projectors, thin film formation, grinding, polishing, and dicing.

A sheet of multilayer thin film filters, which consists of approximately 150 layers, requires high reliability.
Since our products all conform to the strict Telcordia Standard, customers do not have to worry about reliability.

Upon request, we can provide NBPF (Narrow Band Pass Filters), edge filters for FTTH (Fiber to the Home), CWDM filters and so on.
