PBS cubes is used to polarize, split and combine beam in a narrow band. The transmitted beam which is parallel to input beam called p-polarized beam, while reflective beam which is orthogonal is called s-polarized beam Broadband Non-Polarizing Beamsplitter Cube’s hybrid coating has certain absorption but minimal polarization sensitivity. Due to the metallic nature of the hybrid coating, those cubes are not intended for use with high power lasers.
