Any MPO jigs for the Proton?

Yes, we do offer MPO workholder jigs for the Proton polisher. They are available for both flat and angle polishing. Please note that Proton uses 2" diameter films and MT processing tends to wear these films fairly quickly. This is typically acceptable for low-volume or repair applications.

Does the KrellTech bare fiber polisher need calibration?

Since the bare fiber polisher features angle adjustability, it is not aligned to a particular orientation and does not require any routine calibration.

Does clamping force or rigidity play a role in preventing chipping of thin films on SiN?

There are a number of variables that can contribute to chipping, especially proper clamping force. We also offer a pressure applicator that holds the chip against the waveguide mounting plate. https://krelltech.com/items/waveguide-pressure-applicator/. Also, diamond films tend to "cut" cleaner.

Can you please tell me if this can be used to fix both ceramic fiber ferrules and the metal style fiber ferrules? Thank you, Rosemary Diaz

Yes, SpecPro supports ceramic and metal fiber-terminated ferrules, as well as glass and polymer types. This is also true for all Krell polishers.

Hello, currently have both Aluminum Oxide & Silicon Carbide PSA 4" pads that we use to polish Glass Die facets. Can you advise on advantages of one type over another? We use these for optical polish after grind.

For a particular abrasive "grit" size, silicon carbide particles are harder and sharper than aluminum oxide. SC will cut a surface faster, but AO will typically provide a smoother finish.
