Single-fiber PC ferrules, developing a polishing process:

Step 5. Conduct a visual inspection.

Your customers will require some type of visual inspection. (Clearly, you cannot ship a connector with a shattered fiber.) After achieving desired geometry values, measure the visual appearance of the end-face, looking for 2 types of defects: pits and scratches. Typically, pitting can be resolved by increasing time during the intermediate (diamond) polishing steps. Consistent appearance of a large quantity of fine scratches (the “skating rink” appearance) is likely due to insufficient time and/or pressure on the final polishing step. Sporadic appearance of a few scratches is likely caused by contamination, due to insufficient cleaning.
