Hello all,

I'm looking for an optical grating test target with random angles and
lines (straight and curved).  I'm looking for chrome on glass, about
2-3 mm square, with a "line width" of less than 5 um.

Any one know of a supplier?

FYI, we're moving ahead with our "under paint" imaging.  We've had
limited preliminary success with reflectance imaging, and we're
continuing with attempts using IR.  Thanks for all the advice.

Best,

Gary
