Resolution Examples
Resolution Examples
Projection radiographs of the standard JIMA RT RC-04 150 nm (left) and 200 nm (right) resolution pattern captured using the NanoTube.
Examples of 150 and 200 nm lines and spaces on the standard JIMA RT RC-04
resolution chart clearly resolved.
From experiment in collaboration with Fraunhofer EZRT using a Si Timepix detector.
SEM micrograph of a siemens star on the left, and a projection radiograph captured using the NanoTube on the right.
The true round spot of the NanoTube is demonstrated by the highly symmetric images of a Siemens-star resolution target. The innermost features are 150 nm.
From experiment in collaboration with Fraunhofer IIS (NanoCT systems) using a Dectris PILATUS3 X CdTe 300K-W detector.
Positional Stability Example
Positional Stability Example
Thanks to the advanced e-beam system of the NanoTube and the integrated thermal control, excellent long term stability is achieved. This graph illustrates the motion of the image (in object coordinates) of the Siemens star mentioned above over 400 exposures during 11 h. It is worth noticing that this image motion also includes motion of the complete setup with sample, stages and detector etc., so that the actual motion of the X-ray spot is smaller.
Excellent Geometrical Access
Excellent Geometrical Access
The end of the transmission target is the most protruding surface to allow for object to get as close as possible.
The front is furthermore wedged to allow for a sturdy cone-shaped object holder.
