Broadband Polarizing Cube Beamsplitter (BPC)

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.

Angle of Incidence:	0º
Angle of Reflectance:	90º
Reflectance:	Rs ≥ 98.8%
Transmittance:	Tp ≥ 95%
