Combined Atomic Force & Confocal Microscope
room temperature platform for ODMR
After decades of evolution in magnetic imaging, combining the
sensitivity needed to detect single electron or nuclear spins with
a spatial resolution of a few nanometers may soon become current
state-of-the-art instrumentation: nitrogen vacancy (NV) nanomag-
netometry based on the principle of optically detected magnetic
resonance (ODMR) is commonly considered the most promising candi-
date to achieve this goal. While there is significant scientific activity
to both reliably prepare appropriate nanodiamonds with tailored NV
center characteristics and to attach them onto AFM tips, attocube
is complementing these efforts by providing an ideal platform for
ODMR: the attoCSFM combines a high-NA confocal microscope for op-
tical detection in transmission with a cantilever based atomic force
microscope, completely built from non-magnetic materials.
The sample environment can be adjusted from ambient pressure to
low vacuum ( ~ 1 mbar), providing integrated temperature control and
subsequent drifts to less than 10 nm/h. Precise relative positioning
of the sample, AFM tip, high NA objective, and an optional permanent
magnet is enabled via 10 degrees of freedom provided by nanopo-
sitioning stages and scanners (positioning ranges 15 mm x 15 mm x
15 mm, scan ranges 20 μm x 20 μm x 7 μm).

Dr. F. Reinhard
The turn-key, yet custom-made design saved us a great deal of time. We had a
cutting-edge research setup within a few months and obtained the first major
result less than one year after delivery of the instrument. Time-to-market had
never been as quick as this.
