DETAILS, FICTION AND MAGNETO-OPTICAL CRYSTAL

For an optical ingredient with some birefringence, you can specify the retardance, and that is the primary difference in stage shifts for the two polarization directions.The lower area of your Michel-Levy chart (x-axis) marks the orders of retardation in multiples of about 550 nanometers. The realm concerning zero and 550 nanometers is called the v
