UV Polarizing Cube Beamsplitter (PCB)
248 nm < λ < 400 nm
Polarizing Cube Beamsplitter coatings are deposited between two optically contacted, right angle prisms. They are designed to separate an incident, unpolarized, monochromatic beam into its S and P polarization components with an extinction ratio (Tp/Ts) in excess of 200:1. The incident energy is split into two orthogonal beams that emerge at 90º with respect to each other. These coatings are also useful for combining two orthogonally polarized beams.
