Gold on Carbon Resolution Test on Special Stub
This specimen has a particle size range from approximately 5 – 150nm. Each specimen has a square grid pattern with large crystals in the centre of each grid square and very fine crystals at the edges of each grid (as illustrated). Medium and high resolution point separation tests may be performed on the same specimen. In addition, the larger crystals show facets which allow an assessment of the grey level reproduction available at high resolution.
