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.

Does it come with the Universal UPC workholders?

All workholders are individually purchased for the base SpecPro. We will send a quotation for your UPC polishing application.

Can these workholder jigs be used with MT style ferrule containing more than the standard 12 fiber single array? Please see attached.

Yes. The fiber count is not critical, as long as the ferrule dimensions meet industry standards.

What is the thickness of the rubber pads?

5mm (0.2 inches).

What size film does Scepter use?

5"
