VIS / NIR Broadband Polarizing Cube Beamsplitter (BPC)
400 nm ≤ λ ≤ 2.0 µm
Broadband Polarizing Cube Beamsplitter coatings are deposited between two right angle prisms that are permanently cemented together. They are designed to separate an incident, unpolarized, polychromatic 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.
