850nm Polarization Maintaining In-Line Polarizer
850nm Polarization Maintaining In-Line Polarizer is a compact fiber optic polarizing component designed to transmit light along one defined polarization axis while strongly suppressing the orthogonal polarization. Integrated with polarization maintaining fiber, it provides stable linear polarization output and high extinction ratio for polarization-sensitive optical systems. Operating at 850nm, this in-line polarizer is suitable for fiber lasers, fiber sensors, interferometers, optical communication systems, polarization-sensitive test setups, and research applications requiring controlled polarization performance. Custom optical power, input/output fiber type, pigtail length, pigtail diameter, and connector options are available.
