Hello, We already own a NOVA Bare Fiber Polishing system with NOVA Workholder for PICs/Waveguides. Is it possible to purchase a single fiber holder separately (image attached)? Thank you, Michael

Yes. Two options are available. A bare fiber Adapter Mount can convert your waveguide workholder into a bare fiber workholder. Or, you can purchase a dedicate bare fiber workholder that is swappable with the waveguide PIC fixture.

Is one of your machines capable to polish a fiber array mounted on a V-grooves?

Yes. Our NOVA GEO system supports FAU applications. Please navigate to that product page.

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.
