Spectropolarimetry, in both its linear and circular guises, is extremely powerful in that it can probe structures at much smaller scales than are accessible with even the best imaging techniques, it can determine the presence and magnitude of faint magnetic fields, and it allows us to peer into regions that are otherwise invisible to the observer, but can be seen through their.
