Aluminum Oxide Lapping Film

Aluminum Oxide Film is recommended when diamond film is not needed, like in many 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. See Final Polish Films for the best final polish film options and see Silicon Carbide Films for more aggressive epoxy and glass removal. ÅngströmLap® Aluminum Oxide Film is the recommended brand by the Fiber Optic Center Technical Team.
