With amazing customer service, I have designed several non-standard dynamic AFM experiments thanks to MLA. I would definitely continue to use their services and recommend them to others in future.

New life to your AFM

Give state-of-the-art capabilities to your existing microscope. The IMP MF-AFM kit contains a lockin amplifier (MLA), specialized software to synchronize MLA with your existing controller (IMP MF-AFM Sofware Suite), and additional signal access module if needed. Works with new and old commercial AFMs such as:

Bruker Multimode (also older Veeco / Digital Instruments)
Dimension Icon
Dimension 3100 (Nanoscope 3 or 4 controller)
Asylum MFP3D
Asylum Cypher
JPK Nanowizard
Nanosurf
NT-MDT
Park Instruments
and more

Construct Your Own Multifrequency Mode

Any type of multifrequency AFM can be easily implemented. You can measure harmonics, intermodulation products, while driving at any frequencies you want. The Drive Constructor has a Python scripting interface for full control of the MLA, to setup the frequency, amplitude and phase of all drive tones, and the frequency of all response tones.

Screen shot of the Drive Constructor panel of in the ImAFM Software Suite: Any multifrequency measurement scheme can be programed with a Python script. Tuning functions help to correctly place the frequencies. Configure Drive sends the calculated waveform to the cantilever shaker. Configure Response determines the drive needed to result in the cantilever oscillating with the calculated waveform.

Calibration

The software contains the latest advances thermal noise calibration methods. The calibration is performed before scanning so all subsequent measurements are displayed in calibrated nanometers and nano Newtons. The software displays useful benchmarks that help you understand your measurement, for example the thermal noise force [N/Hz1/2] and the noise floor of the detector [nm/Hz1/2]. Recalibration is easily done at any time and the software keeps track of all calibrations. Calibration of both flexural and torsional resonance is implimented.

Extend with Intermodulation AFM

Extend the Multifrequency AFM Suite with any of the Intermodulation AFM-modes, our family of specially crafted AFM modes. Based on over 10 years of research and dozens of peer-reviewed publication these modes take you beyond the raw data to qualitatively and quantitatively new material insights.
