These parameters are: the wavelength range over which the polarizing beam-splitter is effective, the angular field of the incident light in which the polarizer or polarizing beam-splitter is effective and the extinction ratio of the desired polarized light to the unwanted polarized light after the light passes through polarizing beam-splitter.Ĭommonly available polarizing beam-splitters can be divided into several types that depend upon different physical principles: pile-of-plates polarizers, reflection polarizers, Polaroid sheet polarizers, polarizers based on birefringent crystals, metallic grid polarizers, and thin film interference polarizers. There are several parameters that can be used to describe the performance of a polarizing beam-splitter. Polarizing beam-splitters are essentially commonplace optical components and are currently widely used in optical instruments, lasers, electro-optic displays, optical recording and in the fabrication of other optical components. These devices perform the function of separating s-polarized light and p-polarized light.
