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.

PM fiber alignment: how well in angle can you set the stress axis? Another way, when I couple two fibers together what the cross coupling will be. Thanks

Using our SV10 Surface Inspection Videoscope combined with our measurement software, PM stress member alignment repeatability is about +/-1 degree.

hello, is there a part number or SKU # for the SpecPro bare fiber/connector polisher for ordering purposes

Yes. The part number for the SpecPro base polisher is "SP4L". Please note, this will require either a connector or bare fiber workholder fixture.

What is the drifference between a work holder and fixture?

Both terms are used in the polisher industry to describe the same device that holds connectors, termini, adapters, etc., and engage with a base polishing machine.
