Can a custom fixture be manufactured for the attached specialized connector? If so, which Krell polishing machine can be used?

Yes. Either NOVA, Scepter or SpecPro base polishers can be used. Please contact forward technical drawings to sales@krelltech.com for review by our engineering group.

Of the four abrasive materials you offer (silicon carbide, aluminium oxide, silicon dioxide, cerium oxide), which material do you recommend for polishing 125um diameter optical fibre (PANDA PM and SM)?

The suggested film types will be dependent upon whether the fiber is being polished bare, or if connectorized. Silicon carbide and aluminum oxide are typically used for bare fibers. Connectorized fiber uses silicon carbide, diamond and silicon dioxide. Please advise your required film diameter.

We have a orbit bare fiber polishing system but the holders we have on accommodate a 125um polyimide to 155um. Now we are using a 125um fiber coated with single layer acrylate bringing dia up to 175um. Do you offer chisel tip fiber holders that will fit a 175um fiber?

Yes, we can fabricate Fiber Adapters for fibers with diameters from 80um to >2mm. We will send you a quotation for a 175um Fiber Adapter.

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.

Hi, we are looking into polishing both FC/PC and FC/APC fibre connectors. Do we need both the FC/APC NOVA™ Workholder and NOVA™ Universal UPC Workholder for FC/SC/ST/LC/MU/SMA Connectors, or does the universal workholder cover FC/APC too? Thanks in advance

You will need two NOVA polishing workholder fixtures for your FC/PC and FC/APC connector application.
