ÅngströmLap® Aluminum Oxide Lapping Film Disc - 8 inch 3µm (micron), PSA, Hole

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 3μm lapping film is typically used as for polishing MM connectors.

The 8" disc is the standard size for the Ultra Tec Ultrapol 1200, some Buelher polishing machine, as well as others.

Pressure Sensitive Adhesive is only recommended when it is completely necessary. Once the film is stuck to the polish surface it cannot be removed and reused. This creates a potential and likely problem of debris adhering to the film that cannot be removed. Any debris that comes in contact with the fiber may cause a scratch. PSA will increase the cost of the lapping film.

A center hole is not recommended unless the polishing machine requires one. A center hole will increase the cost of the lapping film.
