Polarizing Beam Splitter (PBS) Cubes

Polarizing beamsplitter cubes overview

Polarizing beamsplitter cubes (PBS cubes) are optical components designed to split incident light into orthogonal polarization states. It functions by transmitting p-polarized light while reflecting s-polarized light. Alie Photonics PBS cubes are widely used in laser systems, polarization control setups, and measurement instruments.

Standard options are optimized for defined laser wavelengths, high-energy variants are engineered for high LIDT, while broadband designs operate efficiently across a wider spectral range. Key parameters include extinction ratio, transmission efficiency, wavefront quality, and laser damage threshold.
