ÅngströmLap^® Sequoia Diamond Lapping Film Disc - 110mm 3µm (micron)

The ÅngströmLap Sequoia Diamond Lapping Film is an abrasive film used for polishing the end-face of fiber optic connectors. Its purpose is to shape the fiber geometries, such as restoring or forming the Radius of Curvature and Apex Offset of the ferrule. Diamond film exhibits an extended lifespan compared to conventional films, and its high-cut rate enables more efficient material removal for a faster polishing process.

The 110mm disc is the standard size for the Seiko Instruments OFL-12 and OFL-15 Series Polishing Machines.
