Key Features and Benefits of the TT-2 AFM

Low Noise Floor With a noise floor <80 picometers, the TT-2 AFM is capable of measuring samples with features from nano-meters to microns.
Direct Drive Tip Approach A linear motion stage moves the probe relative to the sample. The probe sample angle does not change, and samples of many thicknesses are readily scanned.
Research Grade Video Optical Microscope With a mechanical 7:1 zoom and a resolution of 2 µm the video optical microscope facilitates locating features, tip approach, and laser alignment.
Multiple Scanners Linearized piezoelectric scanners with several ranges are available to optimize scanning conditions.
LabView Software The TT-2 uses industry standard lab view software. For customization, the systems VI's are readily available.
Modular Design Once you buy the TT-2 AFM you can add options and modes such as focus assist, image logger, lithography and liquid scanning when you are ready.
Simple Probe Exchange With the removable probe holder, exchanging probes is simple, and takes less than a minute.
Ligh Lever Large Adjustment Range Because the TT-2 has a large adjustment range on the laser and photodetector, probes from all major manufacturers can be used.

TT-2 AFM Stage

The TT-2 AFM stage has excellent thermal and mechanical stability required for high resolution AFM scanning. Additionally, its open design facilitates user modification.

Rigid Frame Design: The crossed beam design for the stage support is extremely rigid so the AFM is less susceptible to external vibrations.
Light Lever AFM Force Sensor: Light lever force sensors are used in almost all AFM and permit many types of experiments.
Integrated Probe Holder/Probe Exchanger: A unique probe holder and clipping mechanism allows quick and easy probe exchange.
Direct Drive Z Stage: A linear motion stage is used to move the probe in a perpendicular motion to the sample. Probe/sample angle alignment is not required, facilitating a much faster probe approach.
Small Footprint: The stage dimensions of 4" X 7" require little space and fit easily on a tabletop.
Precision XY Stage with Micrometer: The sample is moved relative to the probe with a precision XY micrometer stage. Thus, the sample can be moved without touching it.
Modes Electric Plug: A six pole electrical plug is located at the back of the stage to expand the capabilities of the TT-2 AFM.
XYZ Precision Piezo Scanner: The modified tripod design utilizes temperature compensated strain gauges which assure accurate measurements from images. Also, with this design it is possible to rapidly zoom into a feature visualized in an image.
Laser/Detector Alignment: Both the light lever laser and the photo detector adjustment mechanism may be directly viewed. This feature simplifies the laser/detector alignment.
Adaptable Sample Holder: At the top of the XYZ scanner is a removable cap that holds the sample. The cap can be modified - or a new cap can be designed – to hold many types of samples.

TT-2 AFM EBox

Electronics in the TT-2 AFM are constructed around industry-standard USB data acquisition electronics. The critical functions, such as XY scanning, are optimized with a 24-bit digital to analog converter. With the analog Z feedback loop, the highest fidelity scanning is possible. Vibrating mode scanning is possible with both phase and amplitude feedback using the high sensitivity phase detection electronics.

28-Bit Scanning: Scanning waveforms for generating motion in the XY axis with the piezo scanners are created with 24-bit DACS and HV amplifiers with 4 bits of gain control, giving 28 bits scanning. Feedback control using the XY strain gauges assures accurate tracking of the probe over the surface.
Phase and Amplitude Detector Circuit: Phase and amplitude in the EBox are measured with highly stable phase and amplitude chips. The system can be configured to feed back on either phase or amplitude when scanning in vibrating mode.
Signal Accessible: At the rear of the EBox is a 50 pin ribbon cable that gives access to all of the primary electronic signals without having to open the EBox.
Status Lights: At the front of the EBox is a light panel that has seven lights. In the unlikely event of a circuit failure, these lights are used to determine the status of the EBox power supplies.
Precision Analog Feedback: Feedback from the light lever force sensor to the Z piezoceramic is made using a precision analog feedback circuit. The position of the probe may be fixed in the vertical direction with a sample-and-hold circuit.
Variable Gain High Voltage Piezo Drivers: An improved signal to noise ratio, as well as extremely small scan ranges are possible with the variable gain high voltage piezo drivers.

TT-2 AFM Software

Software for acquiring images is designed with the industry standard LabVIEW™ programming visual interface instrument design environment. There are many standard functions, including setting scanning parameters, probe approach, frequency tuning, and displaying images in real time. LabVIEW™ facilitates rapid development for those users seeking to enhance the software with additional special features. LabVIEW also enables the TT-2 AFM to be readily combined with any other instrument using LabVIEW.

TT-2 AFM Modes

Modes Included with the TT-2 AFM:
The most commonly used modes are included with the TT-2 AFM. A simple drop down selector is used to select and display images in each of the modes.

Non-Vibrating (contact) In non-vibrating mode the deflection of the cantilever is held constant as the sample is scanned. This mode is used for hard samples, and for training purposes.
Vibrating (tapping) A piezoelectric ceramic is used to vibrate the cantilever at resonance. The amplitude of vibration is held constant as the sample is scanned. Both soft and hard samples are scanned with vibrating mode.
Phase While scanning in vibrating mode and holding the cantilever vibration amplitude constant, the phase shift between the drive signal and photo-detector are displayed. The phase image gives a map of the relative hardness at a sample's surface.
Frictional Force With the 4 segmant photodetector in the TT-2 AFM the L-R signal can be captured and displayed while scanning.

AFM cantilever resonance frequency shown in software

With the window above, the resonance frequency of a cantilever is readily measured. Additionally, the phase characteristics of the probe-sample interaction are captured.
