TESCAN VEGA3 LMU scanning electron microscope with LaB6 (or W) cathode that can be operated in a high-vacuum mode for coated/conductive specimens, as well as a low-vacuum mode for non-conductive specimens in their natural state.
Automated stage, secondary electron (SE) and backscatter (BSE) detectors.
Nordlys Max 3 EBSD camera and XMaxN 50 EDS detector with Aztec Software.
Separate or simultaneous EBSD and EDS mapping, EDS point analyses.
Phase map of a sample of Aheim dunite after processing of the raw data with MTEX. White areas are not indexed.
EBSD data color-coded by inverse pole figure. The similar colors of the majority of grains indicates a strong lattice preferred orientation.
Individual grains color-coded relative to the deviation from their mean orientation accentuating grain internal deformation. Gray colors indicate uniform orientation.
Fracture surface of 3-D printed plastic.
Example of a wide-field image. This enables easy navigation on large samples.
Stomata on a freshly picked oak leaf. Images were taken under high vacuum with sample as is.
EDS map showing the distribution of Ca in a sample of Anita Bay peridotite. Brightest areas are melt and cpx, darker grains are Ca-rich opx. Olivine is darkest. Field of view: 1 mm
BSE ‘panorama’ of a peridotite, optimized for contrast. Each image tile in the panorama is 1 mm on a side. Dark grains are orthopyroxene, lighter gray olivine.
