450/532nm Polarization Maintaining Fused WDM
The 450/532nm Polarization Maintaining Fused WDM is a compact passive wavelength division multiplexer designed for combining or separating 450nm and 532nm laser signals in polarization-maintaining fiber systems. Manufactured using fused biconical taper (FBT) technology, this PM WDM offers low insertion loss, high isolation, and excellent polarization extinction ratio for demanding visible wavelength applications.
Built with PM460 polarization-maintaining fiber, the device maintains stable polarization performance while minimizing signal degradation. It is suitable for laser delivery systems, biomedical instrumentation, spectroscopy, fiber sensing, and quantum optics applications requiring reliable wavelength multiplexing in the visible spectrum.
This 450/532nm PM Fused WDM features compact packaging, high return loss, and stable operation over a wide temperature range, making it ideal for OEM integration and laboratory optical systems.
