SkyScan2011 x-ray nanotomograph
The SkyScan 2011 is a revolutionary laboratory nano-CT scanner
with spatial resolution in the range of hundreds of nanometers.
This spatial resolution in volume terms is equal to or better
than that of synchrotron tomography. For the first time true
sub-micron tomographic imaging is available in a laboratory
instrument.
The 2011 nano-CT employs an open-type x-ray source with a
LaB6 cathode which achieves the unprecedented focal spot size
of <400nm. At this small spot size, small-angle scattering
enhances object details down to 150-200nm. A sophisticated
object manipulator allows object positioning and rotation
with an accuracy of better than 100nm. The x-ray detector
is based on an intensified CCD with single photon sensitivity.
The object is scanned under normal environmental conditions,
without any coating, vacuum treatment or other preparation.The
full range of SkyScan software is supplied, including fast
volumetric reconstruction, software for 2D / 3D quantitative
analysis and for realistic 3D visualization.
