Implement Custom Analytical STEM and Electron Diffraction Workflows with ExpertPI in Python

The demand for nanoscale material characterization is growing, yet most analytical STEM platforms struggle to balance routine usability with full analytical flexibility. Tescan TENSOR changes that situation.

Designed from the ground up for multimodal analytical STEM including precession-assisted 4D-STEM, TENSOR offers a unified solution that accommodates every user: from operators focused on fast, reproducible data to developers building next-generation measurement techniques.

Through the Explore™ and ExpertPI™ software suites, users gain intuitive access to automated workflows or full instrument control, with seamless data export and Python-based scripting. Whether for studying crystallinity, grain distributions, internal strain, or novel structures in new materials, Tescan TENSOR streamlines research workflows now and into the future.

Why Choose TENSOR

for 4D-STEM Research?

01
Root of the Problem

Advanced STEM Is Too Often Segmented

Many electron microscopes offer STEM capabilities, but few integrate them in a way that supports both routine operation and analytical methods development. Existing platforms often rely on fragmented software environments, limiting access to core functions and requiring complex coordination between hardware modules.

For emerging applications such as 4D-STEM, differential phase contrast, or ptychography, these limitations restrict method development and constrain the speed of data acquisition. Users are forced to choose between simplified tools or full but cumbersome access at highly experimental setups, an unsustainable compromise in multi-user and multi-application labs.

Materials and Methods

Explore™ and ExpertPI™ in Action

Tescan TENSOR introduces a new model of an analytical STEM platform, featuring two distinct software environments:

Explore™: Designed for general users, this interface includes automatic microscope alignment, high-resolution ROI navigation, and pre-configured measurement modes (e.g., 4D-STEM Orientation/Phase Mapping, Strain Mapping, EDS Tomography). Data can be processed on-the-fly and exported in standard formats (e.g., HDF5) for compatibility with external tools and software packages.

ExpertPI™: Provides unrestricted access to all microscope functions via a customizable Python-based interface. Researchers can script and test new acquisition routines, integrate third-party data processing tools (such as LiberTEM, py4Dstem, or HyperSpy) and build new workflows for advanced STEM experiments 

03
Results and Discussion

Productivity Meets Precision

Tescan TENSOR successfully bridges the usability gap in electron diffraction STEM analysis. Labs benefit from faster dataset acquisition and reduced downtime, while expert users gain complete experimental freedom. The ability to switch optical modes within seconds means that multiple advanced measurements can be run on a single sample without reconfiguration. The open API environment allows for the integration of external Python functions and packages into custom analytical STEM workflows.

Outcomes include:

01

Higher experiment throughput in routine imaging environments

02
Reliable, reproducible datasets for orientation, strain, and phase mapping
03
Full compatibility with modern Python-based 4D-STEM analysis tools
04
Long-term adaptability through custom interface development

With Explore™ and ExpertPI™ working in parallel, TENSOR enables a complete STEM ecosystem, supporting today’s workflows while empowering tomorrow’s innovations.
