Scanning electron microscope

Overview

The TESCAN CLARA is an ultra-high-resolution scanning electron microscope (SEM) located at the Interdisciplinary Nanoscience Center (iNANO) at Aarhus University. This state-of-the-art instrument provides advanced imaging and analytical capabilities for the detailed characterization of a wide range of materials. The CLARA SEM offers high-contrast, field-free imaging, making it particularly suitable for nanoscale investigations in materials science, nanotechnology, and life sciences. Equipped with a multi-detector system, it enables researchers to selectively collect electrons for enhanced imaging contrast and detail.

The SEM is an essential tool for iMAT’s research activities, supporting high-resolution imaging, compositional analysis, and structural characterization of advanced materials. Its capabilities make it ideal for applications ranging from nanostructure examination and thin-film analysis to battery materials research and biological sample imaging. 

Key Capabilities

Furthermore, the SEM CLARA supports various advanced imaging and analysis techniques, including:

  • Energy Dispersive X-ray Spectroscopy (EDX/EDS)

    • Identifies elemental composition by detecting emitted X-rays.
    • Provides chemical mapping for micro- and nanoscale materials.
    • Helps with failure analysis and contamination detection and complex material compositions.
  • Electron Backscatter Diffraction (EBSD)

    • Determines crystallographic structure and grain orientation.
    • Used for studying microstructure evolution, grain boundary analysis, and deformation mechanisms.
