The Nanotom S with its high-power nanofocus tube and stabilised ultra-precision mechanics invades the sub-micron range in voxel size. The Nanotom S was the first 180 kV / 15 W nanofocus computed tomography system. The Nanotom S is the inspection solution for a wide range of 3D CT applications. Once scanned, the fully three dimensional CT information allows many possibilities for analysis, e.g. non-destructive visualization of slices, arbitrary sectional views, or automatic pore analysis. Since the whole geometry of the object is scanned, precise 3D measurements of complex objects are possible.
