SQUID microscopes can also be used to image magnetization in slices taken from rock samples with sub-mm spatial resolution. This can yield highly detailed maps with the ability to resolve a single grain in a rock.


Tristan's model SMM-401is a powerful non-contact, scanning microscopy for imaging magnetic field distributions. The SMM-401 offers unparalleled spatial resolutions (better than 100 mm) and moment sensitivities (better than 10-15 Am2).
