780-2050nm PM Beam Splitter/Combiner

The core function is based on the polarization state of light, either combining two orthogonally polarized beams into a single fiber or splitting one beam into two orthogonally polarized beams. It is primarily used in fields such as fiber lasers, fiber sensing, coherent communications, and life science imaging.
