blade test
1

your metal object got you near a serious MTF blade test:

You could use a backlit razor blade as target, and then analyze a section of the blade edge using mtf_mapper.  Considering the tiny DoF, you should move the target in ~ 0.1 mm steps to find optimal sharpness after analysis.

Such tests were discussed in an earlier thread.
