In which Γ would be the quantitative retardation of the material, t may be the thickness with the birefringent crystal (or product) and B is birefringence as outlined above. Variables contributing to the worth of retardation are classified as the magnitude of the real difference in refractive indices to http://optical-mirror58148.bloggin-ads.com/20347815/not-known-factual-statements-about-birefringent-effect
