These 6" x 6" sheets have a 30 µm grit and are sold in a pack of 5. To use, drop distilled water on to the sheet and polish in a figure-eight motion using an appropriate polishing puck. We recommend using these sheets in conjunction with our four other polishing films for ceramic ferrules sold separately.
Thorlabs offers lapping (polishing) sheets to polish a connector after the fiber has been epoxied into the ceramic ferrule. Polishing or Lapping Film is composed of tiny particles glued to a substrate. By moving the connector over the polishing film, excess material is removed and the fiber end is polished. Different grades of polishing film are used in successive polishing cycles. Each polishing cycle uses a finer grit paper.
