A Deep Dive into Birefringent Materials and Applications of Wave Plates
Introduction to Wave Plates Wave platesĀ are important optical components for controlling the polarization state of light. They are also called retardation plates or phase plates. Wave plates are typically made of birefringent materials, most commonly quartz crystal. As the name suggests, birefringence has different refractive indices for light with different polarization directions, thus separating incident …
