Description：
The 2 μm Filter Wavelength Division Multiplexer series is based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation
and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating.
