Polishing films for fibre optic terminations

Tech Optics offers a comprehensive range of 3M abrasives for polishing fibre optic terminations. These abrasive films are available in sheet or disc sizes. Polishing films are precise alternatives to messy slurries that require time-intensive cleanup. These films contain proprietary high performance silica and resins coated on 3mm films.

We offer, below, advice on processes for a number of the commonly used polishing machines. While neither Tech Optics nor 3M offer any guarantee or accept any liability for these processes, you will find that using 3M polishing films and following the guidelines you will achieve a process that will only require small adjustments to obtain the result you require. The 3M863XW and 3M865X finishing films produce Ultra PC finishes on spherical polish connectors.
