Modular hardware and software concept

User interface

The MATRIX Graphical User Interface has been optimized for improved work flow and consists of control windows (for setting parameters) and display windows (to visualize the data acquisition). The Scan control window provides a quick method of viewing and setting the imaging parameters. Media - like buttons are used to start, stop, pause and restart a scan.

PLLGuide Advanced oscillation control

MATRIX 4 includes the capability for various levels of control in setting up the oscillation of probes (cantilever/QPlus® sensors). The fully automated process uses software which follows an integral routine for finding the resonance frequency to set overall parameters, providing reliable and safe measurements. Advanced users can tailor this pro-cess at every step by setting the target bandwidth for amplitude or PLL control, and optimize the ratio of speed and signal-to-noise. If needed, full access to all regulation parameters is possible.


Advanced Tip protection to ensure tips are protected from unwanted crashes, the new MATRIX 4 hard- and software allows for triggering of a defined tip retraction depending on phase, amplitude, damping or arbitrary signals in a weighted mixture. For special applications, this function can also be modified. The fast tip protection-on minimizes the risk of unwanted modification or destruction of the probe. This leads directly to continuous, stable high performance AFM measurements.


Tunnelling & force spectroscopy

The MATRIX Control System realizes an n-dimensional concept for data acquisition and data handling and is therefore the ideal platform for tunnelling and force spectroscopy. The spectroscopy control window provides a quick method of viewing and setting parameters such as start and end values, number of points, grid settings, slew rates, delay times and the spectroscopy mode. It also provides activation of ramp reversal and repetitions (multiple curve measurement). The MATRIX Automated Task Environment (MATE) allows the user to modify the standard set up for custom experiments. 


Manipulation & lithography

The concept of digital control of the MATRIX Control System offers predefined procedures for manipulation but also the flexibility for user specific programmable interactions. The MATRIX Automated Task Environment (MATE) or the remote access interface give access to more individual manipulation processes, for example lithography experiments.


Automatic drift correction

The MATRIX Control System virtually eliminates sample drift using an image correlation technique with Fast Fourier Analysis. Based on a reference image the MATRIX software continuously calculates and automatically applies drift vectors for x and y after every image is acquired. Two regulation parameters are available for fine-tuning of the drift correction behaviour.


TWIN Regulator

Instead of mixing or switching input signals, the TWIN Regulator has two independent complete feedback loops, allowing for separate but simultaneous optimization of the two regulation signals. Therefore the TWIN Regulator dramatically improves the efficiency of research work by enabling a seamless transition between modes. The TWIN Regulator also opens up chances for unique experiments by combining or mixing different feedback signals.
