CSRayzer’s Polarization Maintaining Isolator(PMI）series product, is an in-line pig-tailed micro-optic component allows light to be transmitted only in the forward direction while blocking the backward transmission. It features high isolation, high extinction and low insertion loss. It is ideal for fiber laser、fiber amplifier、fiber communication and fiber sensor.
