Is there a MIL or ISO spec that addresses cosmetic defects (scratches, voids, etc) on PVD deposited metal coatings (specifically solderable perimeter metals) on optical components?
MIL-13830B and ISO 10110 only cover optical coatings.
There are all manner of specs for electrodeposited (plated) gold, but I'm not finding anything specific to PVD solderable metal systems (NOT mirrors).
Thanks for any help,
Tom
