Decode the Nanoworld with the Next Generation of AFM

You’ve been expecting something genuinely new from the AFM/SPM industry, but for many years you’ve only seen tweaks to old technology. Now Asylum Research introduces the Cypher™ AFM, the first totally new small sample AFM/SPM in over a decade. More capability, more control, more functionality, more modularity, and more resolution – all with >20X faster scanning and striking ease of use.


 

Closed loop atomic resolution using sensors in all three axes ensures the highest resolution and most accurate images possible today.

With the Cypher AFM, you no longer have to choose between the accuracy and control of closed loop and the low noise of open loop. Asylum’s third generation NanoPositioning System (NPS™) sensors are the quietest in the world today.

With positioning accuracies better than 60 picometers in X, Y and Z, you not only achieve atomic resolution in closed loop, you also get the most accurate measurements, positioning and nanomanipulation possible.

SpotOn Alignment

SpotOn Alignment Just click on the desired spot location and the motorized stages automatically align the laser spot. The photodiode signals are also automatically centered.


 

Laser spot sizes as small as 3µm enable high-speed AC imaging with small cantilevers. Cypher provides the industry’s smallest spot size, allowing you to use cantilevers smaller than 10µm for fast imaging and sub-picoNewton force measurements.

Small Cantilevers

>20X Faster Scanning Small cantilevers provide much higher resonant frequencies than conventional cantilevers without an increase in stiffness.


 

The blueDrive Photothermal Excitation option makes tapping mode imaging simpler, more stable, and more quantitative. blueDrive produces an almost ideal cantilever response by directly exciting the cantilever photothermally. This provides significant ease of use and performance benefits for imaging topography, mechanical, electrical, and magnetic properties in air and liquids.

 
blueDrive


Designed from the Ground Up
for Superior System-Wide Performance

Cypher’s proprietary system-level mechanical design is inherently immune to normal environmental vibration, eliminating the need for additional isolation add-ons for most labs. The integrated system enclosure allows for thermal control and provides additional acoustic isolation for noisy environments.

This system-level design creates images of atomically flat samples that are free of periodic noise. Cypher also features unimpeded 180 degree optical/mechanical access to your samples and a small 40x42cm footprint that conserves lab space.

 
Enclosure


 

Interchangeable modules broaden your options for applications and scanning modes. MultiLux™ source modules are available with laser diodes and low-coherence SLDs in a variety of spot sizes to provide optimal signal-to-noise over a wide range of cantilever lengths. Module exchange takes only a minute.  

MultiLux Optics

MultiLux Optics The focused spot size can easily be changed to fit the size of the cantilever being used. Here, two different spot sizes are shown on two different cantilevers. The small spot has dimensions of 3x9µm.


 

High resolution top-view optics with Köhler illumination provide crystal clear viewing of your sample and tip. Cypher’s custom optics with 20X objective are limited only by physical diffraction. You’ll see sub-micron resolution over a 690x920µm field of view with digital zoom and pan.

User Testimonials

"Cypher is truly the first third generation AFM. The Asylum Research folks have looked at everything that limited AFM performance in the past and addressed all of them in this new design. Cypher has better resolution, less noise, less drift, is more accurate, is able to scan faster and, on top of that, is the easiest to use AFM I have ever seen -- and I’ve seen pretty much all of them while doing AFM since the first DI AFM was introduced 20 years ago.

In terms of speed and ease of use, my student timed how long it took him to be successfully imaging from the time he walked in the door -- 90 seconds! He accomplished in two hours what would have taken a whole day on our existing Veeco AFM. I had previously burned months of graduate student effort on AFM projects that were not successful in getting the images we wanted. With the Cypher we can get most of these images the first time – much faster than before and without using special cantilevers."

Bruce Parkinson, University of Wyoming


"Cypher, from my understanding the first one built, generated publication-quality data on the show room floor at MRS 2008. I think this says it all, an AFM so stable it can image molecular conformation in protein nanofabrics ~10nm thick in the old Hynes exhibition hall with thousands of people in attendance and trains running underneath. Cypher clearly sets the standard in terms of performance. Plus, Asylum Research also has the best service in the business."

Adam Feinberg, Harvard University

 

"The Cypher is the best AFM I have ever used. For our group it has allowed seamless integration of spectroscopic modes for probing contact mechanics in polymers, ionic diffusion in energy storage and generation materials, and polarization switching in ferroelectrics and multiferroics in one flexible, high-stability platform. Cypher makes the work we do possible."

Stephen Jesse, Oak Ridge National Laboratory

 

"Our new Cypher system is exceptional in terms of performance, automation, imaging speed and ease of use. I'm already recommending Cypher to my AFM colleagues."

Bryan Huey, University of Connecticut

 

"Cypher is by far the best, most stable and most configurable AFM I have ever used"

Andras Kis, EPFL Switzerland



“Cypher is one fantastic AFM.   It sets the standard for both resolution and ease of use.  It makes routine characterization easy and opens many possibilities for high resolution imaging. We're really excited to have this instrument in our lab.”

Raymond R. Dagastine, Department of Chemical and Biomolecular Engineering, University of Melbourne

 

“We were delighted to host a team of researchers from Asylum Research to the LCN in London to demonstrate the capabilities of their new Cypher atomic force microscope. During this three-day event, our researchers had the chance to try this new high resolution microscope and were left with a very positive experience. I believe Cypher is one of if not the best high performance AFM on the market. It shines by its combination of high-resolution and ease of use.”

Laurent Bozec, London Centre for Nanotechnology (LCN)

 

“Cypher is a great machine and I am very excited by the research possibilities.”
