Bruker AFMs provide highest resolution and sensitivity. Atomic resolution is achievable on our smallest system, N8 ARGOS, and the large sample platform, N8 TITANOS. N8 NEOS and N8 RADOS achieve sub-Ångstrom resolution, sufficient to clearly resolve atomic steps and carbon nanotubes.

The resolution attainable with the NANOS add-on AFM for upgrading optical microscopes is heavily dependent on the stability of the optical microscope it is installed on. Even though optical microscopes are not built for atomic resolution, Bruker provides accessories - e.g. active anti-vibration platforms and acoustic enclosures - that make upgraded optical microscope-AFMs an inspection tool with nanometer resolution.
