ÅngströmLap® Aluminum Oxide Lapping Film Disc - 2.75 inch 12µm (micron)

ÅngströmLap Aluminum Oxide Lapping Film is recommended when diamond lapping film is not needed, like in many fiber optic multimode applications. Some aluminum oxides can even be used as the final polish. The 0.5μm and 0.3μm will produce return losses of -50 dB or better, but because they cut the glass at a much quicker rate than the ceramic, undercut may occur. Aluminum oxide 12μm lapping film is typically used as for polishing MM connectors.

The 2.75" disc is the standard size for the Seikoh Giken SFP-70D and SFP-70D2 Polishing Machines.
