Polarizers » Cube Beamsplitters |
|||
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. |
