ÅngströmLap^® Aluminum Oxide Lapping Film Disc - 4 inch 1µm (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 1µm lapping film is typically used as for polishing MM connectors.

The 4" disc is the standard size for the Seikoh Giken SFP-100D, Ultra Tec UT-8808 (old), Minipol-1, Siecor SP500, Domaille FS500 and all Krell Polishing Machines.
