Overview
This 3um diamond lapping film is a high-precision consumable designed for the consistent machine polishing of fiber optic connector end faces. Using industrial-grade diamond abrasive, these films ensure uniform material removal to achieve optimal back reflection and insertion loss characteristics.
Each 4-inch diameter disc is engineered with a durable 3 mil backing, providing the necessary rigidity and flexibility required for automated polishing processes. This package includes 10 sheets, intended for professional use in laboratory or production environments where precise surface geometry is required.

Frequently Asked Questions
Is this film adhesive-backed?
No, these discs feature a plain, non-PSA backing for use with vacuum or mechanical retention systems.
What is the grit size of this disc?
This is a 3um (micron) diamond lapping film, identified by its pink color.
Are these compatible with my polishing machine?
These 4-inch discs are standard-sized and compatible with most fiber optic machines that use 4-inch consumables.
Can I use these for hand polishing?
While primarily designed for machine use, the 3 mil backing is sufficiently stable for precision hand-polishing applications.
Why is the color significant?
The pink color-coding helps technicians quickly select the 3um grit stage during multi-step polishing sequences.
