ÅngströmLap® Sequoia Diamond Lapping Film Disc - 5 inch 30µm (micron), PSA

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.30µm 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 5" film disc is the standard size for the Domaille APM-HDC-xxxx Series, Seikoh Giken SFP-5XX Series and Ultra Tec UT-8812 or UT-8808 Polishing Machines.

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.Any debris that comes in contact with the fiber may cause a scratch.PSA will increase the cost of the lapping film.
