Record grooves under an electron microscope

Chris Supranowitz is a researcher at The Insitute of Optics at the University of Rochester. Along with a number of other spectacular studies such as quantum optics, trapping of atoms, dark states and entanglement, Chris has decided to look at the relatively boring grooves of a vinyl record using the institute’s electron microscope. Well, not boring for me.From what I read, it’s not just a simple matter of sticking a record under a fancy microscope, as there is a lot of preparation such as gold-sputtering the surface and post-processing to be done. Having said that, the results are very cool:
