OpticStudio is able to model this type of material in Sequential mode by utilizing the Birefringent In and Birefringent Out surface type alongside the multi configuration editor. This material feature may be applied in a myriad of optical systems, but is most commonly used in liquid crystal displays, retarder plates, polarizers. The article is accompanied by a ZIP archive containing the samples used and a macro.īirefringent materials possess two refractive indices that split light into its two linear polarizations. This article explains what birefringence is and how OpticStudio models birefringence.Ī model of a two-crystal birefringent polarizer is described, as well as the extinction ratio computation of the polarizer for a general ray.
