Key Features and Benefits of the B AFM

7-Step Scanning Software The B AFM 7-Step Scanning Software is designed for casual AFM users that want to obtain AFM images without the expertise. A user-friendly design makes the B AFM ideal for teaching students the basics of AFM theory and operation.
Intuitive Light Lever Design A unique design of the light lever makes aligning the system a routine procedure for users with limited experience. A removable probe holder makes changing probes quick and easy.
Linearized X, Y, and Z Scanners Piezoelectric X, Y (50 µm) and Z (17 µm) scanners incorporate strain gauges that provide linear scans and rapid zoom-to-feature capabilities.
Standard AFM Scanning Modes Scanning modes for the B AFM include vibrating (tapping), non-vibrating (contact), phase, and LFM (Force/Distance). These modes will allow users to scan the most common types of samples.
Acoustic Enclosure The B AFM is encased in an acoustic cabinet made from ¾” MDF and acoustic foam, creating a vibration isolation environment that will provide high-quality scans on almost any lab bench.


Education The B AFM is ideal for educating students on the theory, operation and applications of an atomic force microscope. One of the advantages of the B AFM for education is the open design of the light lever force sensor.
Routine Scanning Routine scanning of samples that are not challenging to scan is a common application for the B AFM. If a noise floore below 300pM is required, we suggest purchasing the AFMControl software and a vibration table.
B AFM Stage

The B AFM is designed with an integrated stage and electronics, making it a compact and portable solution for researchers and engineers.

Simplified Key Operational Steps

Aligning the AFM light lever A unique feature of the B AFM light lever is that the probe is moved to a pre-established position identified with the video optical microscope, therefore removing inaccuracy when aligning the laser.
Exchanging probes With the removable probe holder, probes can be exchanged in less than a minute. A special support is provided for holding the probe holder when it is not in the light lever force sensor.
Exchanging samples Samples mounted on metal disks are held in place with a magnetic holder at the top of the piezoelectric stage.

Key Components of the B AFM

Video Optical Microscope Included with the stage is a video optical microscope with 200X magnification. The video optical microscope is used for locating features on samples for scanning, aligning the light lever, and facilitating probe approach. LED lights at the bottom of the video microscope illuminate the sample.
XY Sample Stage The location on a sample can be selected for scanning with the XY positioner mechanism, with a range of 6 x 6 mm. The controls for the XY positioner are located conveniently inside the acoustic enclosure on the surface of the AFM stage.
Enclosure Both structural and acoustic vibrations are reduced with the front opening enclosure. The enclosure is made from high-density material and is lined on the inside with noise reducing foam. Handles on the sides of the enclosure make transporting the AFM easy.

The control electronics circuits in the B AFM are the same as those used in over 250 AFMs by AFMWorkshop customers globally, ensuring reliability. The electronics include a high fidelity analog control loop for measuring topography, and 24-bit scan DACs for driving the X and Y piezoelectric ceramics. Our unique design offers high resolution as well as a high dynamic range.

B AFM Software

The B AFM software is designed for casual users that want to obtain high-quality AFM images without being AFM experts. Furthermore, the B AFM is great for teaching students the basics of AFM operation and training.

3. Phase image of polymer

The following images are of dried 1 part epoxy paint.

Top Left – 2 micron X 2 micron topography image of the epoxy paint sample. Physically the sample is very smooth. The surface texture (Ra) is 35 nm.

Top Right – Phase image shows that the sample two separate phases. The phases separations are homogeneous across the sample.

Bottom Right: The size of one of the phases is 72 nm in width as measure in this line profile.

4. Polished Copper

A piece of copper is polished first with 800 grit sandpaper (top left image), and then with 2000 grit sandpaper (top right image). By direct visualization of the surfaces, the specimen polished with the 800 grit paper appears much courser than the surface polished with the 2000 grip paper. This observation is born out in the surface texture calculation. The Ra for the top left image is .189 microns, and the Ra for the top right image is .097 microns.

5. Aluminum Foil

Aluminum foil if manufactured using a rolling process. This is accomplished in a rolling mill, where the material is passed several times through metal rolls called work rolls. As the sheets (or webs) of aluminum pass through the rolls, they are squeezed thinner and extruded through the gap between the rolls. At the end of the process, one side of the foil is smooth and appears shiny, and the other side of the foil is rough and appears dull.

B AFM Modes

Standard with every B AFM are non-vibrating (NV) mode and vibrating (V) modes for making topography scans. Additional modes included with the product are lateral force imaging as well as phase mode imaging. All of the scanning modes that can be implemented with a light lever AFM are also possible with the B AFM.

Vibrating Mode Vibrating mode (tapping) is the most common mode for measuring topography images with an AFM. Probe/sample forces as small as a few piconewtons are possible with vibrating mode.
Non-Vibrating Mode In Non-Vibrating mode (contact), topography images are measured with a cantilever/probe having a very low force constant. Non-vibrating mode is most often used for large area scans on hard materials.
Phase Mode Phase Mode images, measured simultaneously with vibrating mode images, show regions of different relative hardness on a sample's surface. Phase mode is especially useful when scanning polymer samples.
Lateral Force Mode Using a four quadrant detector, the torsion of the cantilever is measured during a non-vibrating mode scan. The amount of torsion depends on the friction between the probe and sample while scanning.
Force/Distance Mode The interaction forces between a probe and surface are measured with F/D mode. In this mode, the deflection of the cantilever is measured as the sample is moved towards the probe.

Optional Modes

MFM Magnetic Force Microscopy - Measure magnetic fields above a surface with this option which includes magentic probes.
EFM Electric Force Microscopy - Electric fields are measured with this mode with the aid of a conductive AFM probe.
C-AFM Conductive AFM – Measure the current between a conductive probe and a surface.
Lithography Write nanoscale patterns with the AFM probe.
Advanced F/D Measures force/distance curves from a feed back and not feedback condition, allows force mapping.

B AFM Options

There are several options available for the B AFM. These can be purchased with the system or added at a later date.

Modes MFM, EFM, C-AFM, Lithography Advanced F/D.
100 micron scanner The B AFM can be upgraded to 100 X 100 micron XY, 17 micron Z scanner.
AFMControl Software* This is the same software used for the TT-2 AFM and includes several advanced features required for more advanced applications.
Vibration Table* With a vibration table the Z noise of the B AFM can be reduced to < 150 picometers.

*Adding the AFMControl Software and Vibration table greatly improves the performance of the B AFM for applications that require measuring and visualizing surfaced features with only a few nanometers in size.
