Wherever Γ could be the quantitative retardation of the material, t will be the thickness in the birefringent crystal (or product) and B is birefringence as outlined earlier mentioned. Components contributing to the worth of retardation are classified as the magnitude of the real difference in refractive indices for https://birefringent-effect58740.ageeksblog.com/5624205/detailed-notes-on-birefringent-effect
