Mineral surfaces under the SEM: 6 new micro-GigaPans
Posted by Callan Bentley
As mentioned yesterday, my student Robin has been having some success lately in making GigaPan-scale imagery using the new desktop scanning electron microscope that our division acquired. They aren’t as super-high resolution as most of the other GigaPan images I post here, but they are very, very small – and thus expand the scope of our imaging initiative. Enjoy exploring: find cleavage planes, microscopic plumose structures, examples showing the constancy of interfacial angles, and more!
