450/635nm Polarization Maintaining Fused WDM
The 450/635nm Polarization Maintaining Fused WDM is a high-performance passive wavelength division multiplexer designed for combining or separating 450nm and 635nm optical signals in polarization-maintaining fiber systems. Manufactured using fused biconical taper (FBT) technology, this PM WDM provides low insertion loss, stable polarization performance, and reliable wavelength isolation for visible laser applications.
Built with PM460 polarization-maintaining fiber, the device maintains the polarization state of transmitted light while ensuring excellent optical stability and low back reflection. Its compact structure and wide operating temperature range make it suitable for integration into precision optical systems and OEM equipment.
This 450/635nm PM Fused WDM is widely used in biomedical instruments, spectroscopy systems, laser combining, fiber optic sensing, quantum optics, and scientific research applications requiring stable polarization and visible wavelength multiplexing.
