Duetto 2

Duetto is a unique non-invasive XRD/XRF instrument based on technology originally developed for space exploration. It collects X-ray diffraction and X-ray fluorescence data from a small region of an object to measure mineralogy and chemistry.

Duetto is portable and can be deployed directly on the object. XRD analysis can be obtained without sampling even for non-movable large artifacts (statues, murals, etc).

The technology inside Duetto derives from NASA’s CheMin instrument inside the Curiosity Mars rover. Whereas CheMin is based on a transmission geometry that requires sampling and grinding the material to coarse powders, Duetto works in reflection and samples are analyzed without preparation. A prerequisite to data quality is sufficiently fine grain sizes which are typically the case with pigments.

Duetto was developed specifically for the Art and Archeometry market. It can be used in the laboratory or deployed in the field (museum, archaeological site, restoration project, etc) using a variety of mounting options.

Duetto 2  is an updated version of Duetto.  While the general concept of Duetto 1 remains unchanged, a number of improvements are being implemented to the new design.

We cannot share the detail design of Duetto 2 at this time. New and improved features include:

  • collinear X-ray beam and laser beam,
  • embedded imaging camera,
  • a lighter power unit,
  • upgraded and more compact X-ray tube,
  • improved clearance to the sample,
  • and more…
