The Nano-Observer AFM microscope is a flexible and powerful AFM. Designed with the ultimate technologies, it combines performance and ease of use. The USB controller offers a real integrated lock-in for better measurement capability (phase detection, Piezo-Response Mode…).
A low-noise laser and a pre-alignment system provide simplicity and high resolution on a compact AFM head. Its intuitive software simplifies all Atomic Force Microscope settings to allow quick and safe AFM acquisitions.
Compact and robust, the Nano-Observer Atomic Force Microscope fulfills the requirements for advanced users or beginners. It avoids laser alignment with the pre-positioned tip system. A top and side view of the tip/sample, combined with vertical motorized control, makes the pre-approach easy.
“The World’s Greatest Performance for AFM Electrical Characterization.”
The ResiScope II is a unique system able to measure AFM resistance over 10 decades with a high sensitivity and resolution. It can be combined with several dynamic modes as MFM/EFM (AC/MAC mode) or KFM single‐pass (AC/MAC III) providing several sample characterization on the same scan area.
During the measurement, the DSP chooses in real time the best gain to optimize the measurement made by the amplifier module (HPA). This operating condition allows a very high sensitivity on all the range of resistivity at a regular scan speed (AFM) . Contrary to other techniques, the current between the probe and the sample is strongly reduced. This has the result of limiting the local effect of oxidation or electrochemistry and protecting the conductive probe from high current damage.

What if… you could have an ultra-low noise LT (9 K chilled tip/sample) STM- AFM/qPlus System in your lab that never needs liquid cryogens –even running 24 hours a day producing atomic resolution images and lengthy, sophisticated STS data?
That would mean your research is Cryogen cost-free, Interruption-free, and Hassle-free. You’d never waste time trying to source LHe or waste money paying upward-spiraling prices. No more interrupted or delayed experiments waiting for cryogen supplies. The hassles and real risks of handling and changing dewars would disappear. You’d spend more time on research. Achieve better results faster.
RHK’s PanScan Freedom delivers all that and more. All the advantages of LT. None of the constraints. Proven atomic resolution 9 K – 400 K. Peer-reviewed published results. XY drift achievable as low as 0.2Å/hour, and Z drift as low as 0.2Å/day. Dedicated STM/STS and also qPlus-AFM. No special Lab set-up or ceiling heights. Straightforward design, easy to operate.
Meet RHK’s award-winning PanScan Freedom, the world’s first closed-cycle cryogen-free system for stable low temperature performance in a surprisingly compact, simple, and affordable package. PanScan Freedom enables you to explore tomorrow’s materials and make discoveries that will keep your laboratory first in science.
Freedom has proven atomic resolution results on materials from crystalline metals to carbon nanotubes, plus world-class low-noise, low-drift STS, without consuming a drop of LHe.
1. Precise positioning of the probe onto a specific area of the sample with a precision of better than 2 microns
2. Light and lens can be adjusted to provide optimum contrast for low contrast samples such as graphene
3. Capability available on up to three separate chamber ports
RHK introduces the all new PanScan Freedom Tesla, the world’s first closed-cycle cryogen-free system for stable low temperature performance in and out of magnet, unprecedented low drift, exceptional spectroscopy performance, and integrated cryogen free superconducting magnet, in a surprisingly compact, simple, and affordable package. PanScan Freedom Tesla enables you to explore tomorrow’s materials and make discoveries that will keep your laboratory first in science.
PanScan FLOW-LT provides a convenient means for researchers to move easily across specific temperature regimes while maintaining a reasonable cryogen budget. It’s efficient, very low noise flow cryostat is ready for LN2 and LHe whenever desired.
Low-cost LN2 provides ~82 K uniformly chilled tips and samples. This is ideal when LT stability is essential but LHe is not essential. LN2 is also useful when pre-testing LT experiment set-ups to ensure success before LHe is committed.
When LHe is crucial to research, the same PanScan Flow cryostat can be used for the coldest, quietest conditions at ~12 K chilled tip/sample.
PanScan FLOW is equipped with many of the same highly effective features as the ground-breaking Closed-Cycle Pan Freedom LT. These include highly effective eddy-current damped spring suspension; 4 ports for in-situ LT deposition; ability to change both tip and sample in 30 seconds; and UHV storage racks for a convenient tip and sample treatment and instant availability. And of course, PanScan FLOW provides the same rock-solid stability and proven results as Freedom.
Sample pretreatment and probe cleaning can be done in the ultra high vacuum chamber, enabling atomic or molecules level resolution observations by ultra low temperature STM/AFM. New probes and accessory devices are available to cope with recent expanding application range.
