    X-Rays Microtomography



    Characteristics :

    - X-ray source ................ 20-100kV,10W,<5µm spot size
    - X-ray detector ..............11Mp, 12-bit cooled CCD fiber-optically coupled to scintillator
    - Maximum object size... 27mm in diameter(single scan) or 50mm in diameter (offset scan)
    - Detail detectability ...... <0.8µm at highest resolution
    - Radiation safety ......... <1µSv / h at any point on the instrument surface

    Principle

    The X-beam passes through the sample, and is then collected by a detector. The X-ray intensity loss between the source and the detector is linked to the atomic structure of the material, that permits to draw the X-Rays radiography (like a medical X-Rays radiography).

    The 2D sample rotation gives different X-Rays pictures (different angles). All those pictures are then collected and re-built to form a 3D reconstruction. Thus the inner structure of the sample can be 3D-observed and inspected.

    Featured accessories :

    Cryogenic freezing system : Ice block observation (sample holder on the left, and 3D-reconstructed sample on the right)

    Micro-positioning sample holder : to improve the sample centering
