Done a little searching here and elsewhere without much luck. I know sources have been mentioned, but I can't find any here.

Looking to replace all my pholes with fresh laser drilled. Can these be made with a +/- .01mm tolerance? I have all my cameras set to about f250, that is, I did the math for the hole-to-film plane distance, and I made a few dozen holes and selected the ones closest to make the math work.

Anyways, a link or ref to a laser pinhole source would be great. Thanks.
