850/905nm Polarization Maintaining Filter WDM
The 850/905nm Polarization Maintaining Filter WDM is a thin film filter-based wavelength division multiplexer designed to combine or separate 850nm and 905nm optical signals while maintaining the polarization state in PM fiber systems. It provides low insertion loss, high channel isolation, high extinction ratio, and stable optical performance in a compact package. With PM780 fiber support and both-axis operation, this PM Filter WDM is suitable for short-wavelength PM fiber laser systems, optical sensing, LiDAR-related optical setups, interferometric systems, test equipment, and other polarization-sensitive applications requiring reliable wavelength combining or splitting between 850nm and 905nm channels.
