ÅngströmLap^® Aluminum Oxide Lapping Film Disc - 5 inch 5µm (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 0.5um and 0.3um 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 5μm lapping film is typically used as for polishing MM connectors.

The 5" disc is the standard size for the Domaille APM-HDC-xxxx Series, Seikoh Giken SFP-5XX Series and Ultra Tec UT-8812 or UT-8808 Polishing Machines.
