This system uses closed loop scanning in all three directions
(x, y and z) for accurate length, height and force measurements.
It can be operated on both a standard stage and on the top of
an Olympus IX 70/71 (Carsen) inverted optical microscope. This
allows sub-micron positioning of the sample in two dimensions
as well as high-resolution optical imaging simultaneous with force
measurements. On the standard stage, top-view optics (to view
the tips and the sample from above) are available. While on the
inverted microscope, the tip can be viewed from below through
a transparent sample. The system is housed in an acoustic noise
enclosure and on a vibration damping table that limit noise to
less than 0.4 nm in the x and y and less than 0.2 nm in the z
directions. Both non-conducting and conducting samples can be
analyzed. Standard scan modes available in fluid and air include
contact mode (with lateral force) and Q controlled AC (with phase).
Push-button calibration of cantilever force constants and closed
loop z-scanning permit accurate force curve measurements. Nanolithography
and nanomanipulation with custom scripting software are also available.
The system is also capable of electrical measurements including
conducting AFM, scanning capacitance and Kelvin probe microscopies.
Metal coated conductive tips are available. The AFM is equipped
with temperature controlled closed fluid cell for biological imaging.
The BioHeater controls and maintains the cell temperature from
the ambient temperature up to 80 degr. C with an accuracy of 0.1
More details about the options offered by the AFM instrument
can be found in the MFP-3D
Manual. Useful information on conductive sample measurements
is contained in Orca Application notes.
Application notes and guidelines for using our recently acquired
Piezo-responce Force Module are posted in the Asylum documents
and PFM3. Other
Asylum Research developments are outlined in the company website,
