Hello,

I was worried about the optical quality of the transparency in such a sensitive test. The second 35mm slide will use .105mm fishing line for 120+ lines per inch for zero interference from the substrata.

Sunfish, I see your Ronchi slide looks to be very thick though. I can see why the slides are so expensive if they are on optical glass that thick.
