Follow-up on the paper sample holder calibration samples idea.?
The paper disc was made bigger as was the hole in the middle. For a this one I wanted a Silver metal sample. Punched a 1/8" disc of 0.998% Ag 0.004" thick as the sample and attached it to Scotch tape "window" that covers the hole from the rear leaving the sticky material inside the hole. No front cover placed over the sample "dot" at this time.
The sighting is improved as expected, while the scans, for all practical purposes, remained the same as they were before when using a much larger postage sized sample of the same material.
