3M Diamond Lapping Film 3x6 1um (25-Pack)

Overview

The 3M Diamond Lapping Film is designed for high-precision fiber optic connector polishing. Utilizing micro-graded diamond abrasives bonded to a uniform 3-mil polyester backing, this film provides consistent and repeatable finishes across various ferrule materials.

Ideal for use in data centers, telecommunications, and field termination environments, these sheets help achieve high connector yields. The film is non-PSA (plain back), making it suitable for standard flat polishing equipment and applications requiring high-quality optical end-faces.
