These unique gold nano particles on silicon provide resolution standards with known and uniform particle size, ideally suited for high resolution tests for SEM, FESEM and FIB/SEM systems. The known particle paired with uniformity provides a real indication of the performance of the SEM of FESEM. The nano gold on silicon resolution standards are available in two size ranges:

30nm for high resolution SEM applications (size is 30nm ± 4nm)
15nm for ultrahigh resolution FESEM applications
Provided on 5 x 5mm silicon wafer chip, unmounted or provided on the specimen mount of your
