Hi, I'm interested in polishing the edge facets of sapphire-substrate photonic chips. I would like to know which polishing pads are available to polish sapphire (available grain sizes etc) and how to order them.

Sapphire components require diamond polishing film. We will send you a listing of available diamond grit abrasives.

How many sheets come in a Pack?

Diamond films are available in packs of 25 sheets. Silicon carbide, aluminum oxide and final polish films come in packs 100 sheets.

Good morning, Is this something you are able to provide? Polishing Film – Alumina Oxide (AO) and Diamond (5.5” x 5.5” sheets) **5.0um AO Foam-Backed Film Part# 0700-2663 We are looking to purchase very large qty. Thank you Laura F&M Micro Products

We can supply these film types, but only in 5", 4", and 2" diameters for use with Krell automated polishers.
