Portable micro-XRF mapping for Cultural Heritage
microScanix is a micro X-Ray Fluorescence (µXRF) imaging instrument designed for field and laboratory work, with an emphasis on portability, high resolution and high throughput.
microScanix is intended for scientists seeking a portable solution for µXRF analysis and elemental mapping without compromising on performance.
microScanix allows collecting spatially resolved XRF data down to 55 µm resolution, and acquire elemental composition maps by raster-scanning the measurement pixel by pixel with its XY stage.
microScanix was developed in collaboration with NASA and LAMS (Sorbonne Université-CNRS, France). Like with other eXaminart products, the technology at the base of microScanix derives from NASA planetary instrument developments programs, and brings unprecedented miniaturization and ruggedness to Cultural Heritage Research.
