A SIMPLE KEY FOR MAGNETO-OPTICAL CRYSTAL UNVEILED

各向异性透明晶体如方解石、石英等的折射率，是其固有的特性，称为永久双折射。The reduce section from the Michel-Levy chart (x-axis) marks the orders of retardation in multiples of around 550 nanometers. The realm among zero and 550 nanometers is named the very first buy of polarization colours, and also the magenta
