AFM - Asylum Research Vero
The Vero is a state-of-the-art interferometric AFM, featuring exceptionally low noise and fast scanning capabilities in addition to advanced scanning modes in air or liquid environments. Maximum lateral scan size on this instrument is 30 µm x 30 µm, and maximum vertical range is 5 µm.
The Oxford Instruments Asylum Research Vero S AFM builds on the popular, easy-to-use Cypher AFM design. The unique feature of the Vero is the QPDI interferometric cantilever detection which measures the vertical displacement of the cantilever instead of the deflection of the cantilever. This minimizes artifacts and ambiguities resulting from changes to local cantilever angle, and it also decreases the noise floor of the instrument related to cantilever detection for more sensitive measurements.
The Vero at MRL includes these upgrades:
- blueDrive photothermal excitation
- Fast Force Mapping
In addition to modes requiring no additional hardware, the Vero is compatible with the following Cypher accessories (shared with MRL's Cypher S):
- Droplet cantilever holder
- Dual-gain ORCA conductive AFM cantilever holder
- Air Temperature Controller (contact staff to perform the hardware swap)
- Scanning Tunneling Microscopy
