PM Polarizers

PM Polarizers (Polarization Maintaining Polarizers) are devices used in optical systems to regulate and control the polarization state of optical signals. Unlike conventional polarizers, PM Polarizers have the additional feature of being able to maintain the polarization state of an optical signal unchanged.

In fiber optic communication systems and other optical applications, optical signals often have a specific polarization state, such as linear or circular polarization, and PM Polarizers are able to adjust the polarization of optical signals while keeping their polarization state constant, ensuring the polarization consistency of the output beam.
