Cutting polarizing filter glass

[MechanoMan]

I have a small "bullet camera" that may benefit from a polarizing filter.

No one makes filters this small. I can get a larger glass filter fairly cheap. I have Taig and those cheap diamond-grit shaper bits you find at Harbor Freight Tools. I'll worry about the mounting later, I just want the glass cut.

I could probably double-sided tape stick this down, put a layer of packing tape on top, and make a spiral pattern with very, very small Z-drops, with some lubricant/coolant mist.

Is this plausible? These shapers aren't designed for plunging, but do have grit on the tops/tips. Would this type of glass survive? Is there a better tool to try?

new to this forum,
you could try a diamond coredrill or find an optical shop like the one that i work at. i have been working with glass for 30 years and have been cutting ,
edging, cnc grinding strange shapes.:
