780nm Polarization Maintaining Fiber Pigtail PM780 Pigtail Slow Axis
The 780nm Polarization Maintaining Fiber Pigtail PM780 Pigtail Slow Axis is designed for high-performance optical systems requiring stable polarization transmission at the 780 nm wavelength. Manufactured with PM780 polarization-maintaining fiber, it effectively preserves the input polarization state by aligning the connector key with the fiber’s slow axis, minimizing polarization fluctuations caused by stress, bending, or temperature changes.
This PM fiber pigtail offers low insertion loss, high extinction ratio, and excellent reliability, making it ideal for precision laser delivery and polarization-sensitive applications. It is widely used in atomic physics experiments, quantum optics, laser spectroscopy, biomedical instrumentation, interferometric sensing, and fiber optic communication systems operating around 780 nm.
Available with FC, SC, LC, ST, and other connector options in UPC or APC polish, the pigtail can also be customized in fiber length, connector type, jacket material, and packaging to meet specific application requirements.
