Polarizing Cube Beamsplitters are formed from two right angle, 45° prisms permanently cemented together.
The hypotenuse is coated with an all dielectric, polarization sensitive coating designed to separate an incident, unpolarized, monochromatic beam into its S and P polarization components.
The extinction ratio (Tp/Ts) exceeds 1000:1 in the transmitted beam. The two orthogonally polarized beams emerge from the cube at 90° with respect to each other.
All entrance and exit surfaces are coated with a high efficiency, narrowband, anti-reflection coating.
