Product Details

Polarizing Beamsplitter Cube, BK7 And SF Glass, Boradband High Extinction Ratio

Overview:

Polarizing Beamsplitter Cubes 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.All entrance and exit surfaces are coated with a high efficiency, narrowband, anti-reflection coating.

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.
