TriLambda Nano-XRM - microscope à rayons X haute résolution de 40 nm

SIGRAY

Le Tri Lambda ™-40 NanoXRM est le microscope à rayons X de laboratoire doté de la plus haute résolution (40 nm) au monde. Il permet d'obtenir des images de la nanostructure interne et des performances optimisées dans un large éventail d'échantillons, allant des cellules et des polymères aux échantillons géologiques et aux métaux.

Plus d'informations

The TriLambda40™ system was developed to help research groups performing XRM experiments primarily at synchrotron setups who are limited by beamtime and who needed ultra-high resolution. The TriLambda40™ advantages at a glance are:

Highest resolution 3D XRM, with 40 nanometer spatial resolution
Patent-pending x-ray source with multiple x-ray source target materials for unique advantages including dual energy imaging and optimization of acquisition speed
Optimized throughput for time-based (4D) & in-situ studies
Designed by the world’s foremost experts on x-ray microscopes

Sigray has developed an ultrahigh brightness x-ray source featuring an x-ray target comprised of multiple materials in close thermal contact with a diamond substrate. Software selection of the target material enables rapid switching between different characteristic x-ray energies of each material, for example:

8 keV (for metallic and semicon samples)
6,4 keV (for ceramics)
5,4 keV (for rock samples, stained cells and bones)
2,7 keV (for unstained cells)
