Medium resolution aluminium-tungsten dendrites

The various spacings created by the dendritic structure of this specimen are suitable for performing point resolution tests and the topographical arrangement of the dendrites for a grey level test. It is non-magnetic, vacuum clean, has no adverse reaction to the electron probe, requires no surface coating and is most useful for working in the probe size range of 25 -75 nm. Supplied unmounted, it can easily be attached to a stub using a conductive adhesive such as silver paint.
