Broadband Polarizing Beamsplitter Cube coatings are deposited between two right angle prisms that are permanently cemented together. They are designed to separate broad incident beam into its S and P polarization components with an average extinction ratio (TP/TS) in excess of 500 : 1. The incident energy is split into two orthogonally polarized beams that emerge at 90。with respect to each other. These coatings are also useful for combining two orthogonally polarized beams. |
