MAX LEVY  DA104
Checkerboard Calibration Target, 60mm x 60mm, with 0.50mm Squares on Clear Soda Lime Glass
Includes NIST Traceable Calibration Certificate

Note that overall dimensions of the glass are 60mm x 60mm, but the checkerboard pattern is only 50mm x 50mm.

These calibration grids were ordered for an automation project, but part of the application ended up requiring Non-transparent white glass, so these were left over.  All are new, individually serialized with matching NIST pages from MAX LEVY.
