ÅngströmLap® Sequoia Diamond Lapping Film Disc - 4 inch 3µm (micron)
D3AT403N1
ÅngströmLap® Sequoia 3um Diamond Lapping Film, 4" Disc with 3mil Backing, Single Disc.
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 4" disc is the standard size for the Seikoh Giken SFP-100D, Ultra Tec UT-8808 (old), Minipol-1, Siecor SP500, Domaille FS500 and all Krell Polishing Machines.
