AuSome Resolution and Calibration Standard for SEM, FIB and FESEM

This AuSome resolution and calibration standard comprises a silicon substrate configured with two discreet populations of large and small gold particles.
The larger (117.3nm, STDV 8.4nm) population of gold particles go from individual particles all the way up to large aggregates.

These islands of aggregated particles can cover micron sized areas.
The large aggregates provide reference points that are easy to focus on at low magnification; thus making the smaller (27.3nm, STDV 6.3nm) particles easy to find.
The small clusters of 117.3nm gold particles provide the sites to check resolution and calibration in the submicron range.
The small 27.3nm gold particles represent the AuSome coating on the silicon substrate to provide high magnification resolution check.

AuSome provides a continuous monolayer of gold nanoparticles with uniform particle size and inter-particles spacing over the majority of the substrate with a higher density at the edges and corner.
