The Thermo Fisher Scientific (TFS) Themis Z G3 aberration-corrected scanning transmission electron microscope (STEM) achieves < 0.6 Å resolution (sample dependent) and is equipped with an optimized monochromator for < 30 meV energy resolution in EELS at 60 kV, a Gatan Continuum electron energy loss spectrometer and image filter, a TFS Super-X energy dispersive x-ray spectrometer system, a segmented STEM detector for fast DPC and iDPC imaging, a Lorentz lens, a 16 megapixel Ceta II camera and a 4D STEM EMPAD camera. Single tilt, double tilt, and tomography holders are available. The instrument can be operated at 60, 200, and 300 kV for the flexibility to accommodate a range electron beam sensitive materials.
