Rendered animation showing how LabDCT works

LabDCT stands for laboratory-based Diffraction Contrast Tomography. It enables you to unlock crystallographic information in your lab. Achieve direct visualization of 3D crystallographic grain orientation in a non-destructive tomography environment with the LabDCT advanced imaging module. Diffraction contrast tomography (DCT), previously available only at a limited number of synchrotron X-ray facilities, can become your routine tool for non-destructive 3D grain mapping. Acquire and reconstruct crystallographic information from polycrystalline samples, such as metals and alloys. Combine grain orientation information with microstructural features observed in absorption or phase contrast tomography, e.g. cracks, porosity network, inclusions. Open new possibilities for the characterization of damage, deformation and growth mechanisms related to 3D materials science. Achieve enhanced understanding of the fundamental materials science behind these processes with microscopic imaging features in three dimensions. Read more

Can you do bond length variability (quasi-Raman spectroscopy) with this unit to see relative/variable strain in a substance?
over 3 years agoJanuary 9, 2018
No, not quite possible to the bond level, as resolved by Raman Spectroscopy. The equivalent of the bond length variability is the lattice constant change under load which is at a slightly bigger length scale. In principle, the lattice constant change under load should be detectable in the elastic range. This is not a ready solution in the current version but is something under development.

Can you inspect blocks of mono crystal CVD diamond?

Should be possible. Samples need to be reviewed on a case-by-case basis since this is not a routine application. The success also depends on the thickness of the coated diamond. Overall, the equivalent diameter of the crystal being imaged needs to be above 40 um.

can this be used to evaluate cracks and grain size of highly irradiated alloys such as stainless steels and Ni-based alloys from nuclear power plants?

Can evaluate surface and sub surface defects (Ferrous safety products) at high speed by this equipment or is there any alternate device available suitable for this application? (

Can this method be used for thin films ~10um thickness or only bulk samples?

Hi Rob,
Thank you for reaching out about LabDCT.
In principle it should be possible to image grains in thin films as long as they have a large enough equivalent size of the grains ( for e.g. a 10 um thick film with large grains in the epitaxial layer of >70-100 um) should work. If you are interested in this application and would like to have a conversation, please reach out to us.
