Neutrino coating is, of course, undetectable. The hard part is stopping the neutrinos by removing their charm and spin (Neuro excels at this, except he does it with forum trolls), then adhering them with gluons to the glass.
But really, it is likely just a nano/fluorocarbon material.
Thanks ahsanford, I appreciate the links. My apologies if I was deviating the thread too much. Was just wondering in a general sense how good these Irix lenses are performing, specifically if anyone around here has used one yet.
