Description

The JEM-ARM300F2 (GrandARM) is a 300 kV double aberration-corrected transmission electron microscope (AC-TEM) with up to 53 pm resolutions in both STEM and TEM modes with x-ray energy dispersive spectroscopy (XEDS), electron energy loss spectroscopy (EELS), and segmented and 4D-STEM detectors for electric and magnetic field mapping. The GrandARM can be used to analyse a wide range of materials with imaging and spectroscopy at the atomic level, including nanoparticles and thin films and can utilise our range of in-situ holders for dynamic experiments.
