Spectral Imaging : Mapping & Linescans

Quartz Imaging set the standard for digital image acquisition systems for SEMs with our Quartz PCI product. Now we’ve extended this technology to acquire high-resolution, fully live-time corrected x-ray maps at high speed. Combining our imaging technology with the high-performance TrueSpectrum pulse processor makes it practical to produce maps faster and with higher spatial resolution than most conventional systems.

Rather than acquiring maps in a single pass, XOne builds up the map through multiple passes of the beam. With every pass you can see the maps take shape. When the results are clear, stop the map and move on to the next acquisition.

XOne uses full spectral imaging. This means that all of the x-ray events that occur at each pixel are recorded. Because all of the data is retained, it is possible to select elements for the map creation before, during and even after data acquisition is completed. Linescans and fully quantifiable spectra from any region in the map can also be generated during and after acquisition.

For each acquisition, maps for different elements can be displayed at different spatial resolutions. Use a lower spatial resolution for trace elements so that the x-ray events are consolidated into fewer pixels. Where you have a dominant element with many x-ray events, display the map at high-resolution so that small features become apparent.

Of course, because it comes from the PCI people, XOne acquires the SEM image at the same time it is mapping. On most instruments, this SEM image will include the micron marker and other data generated by the microscope.
