THE SMART TRICK OF BIREFRINGENT CRYSTAL THAT NOBODY IS DISCUSSING

For an optical component with some birefringence, one can specify the retardance, which can be the primary difference in section shifts for The 2 polarization directions.The reduced segment from the Michel-Levy chart (x-axis) marks the orders of retardation in multiples of around 550 nanometers. The realm in between zero and 550 nanometers is known
