ÅngströmLap® Sequoia Diamond Lapping Film Disc - 8 inch 1µm (micron), PSA, Hole

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 8" film disc with a center hole is the standard size for Ultra Tec Ultrapol 1200 Polishing Machines, some Buehler Polishing Machines, and others.

Pressure Sensitive Adhesive is only recommended when it is completely necessary. Once the film is stuck to the polish surface it cannot be removed and reused. This creates a potential and likely problem of debris adhering to the film that cannot be removed.

A center hole is not recommended unless the polishing machine requires one. A center hole will increase the cost of the lapping film.
