Description:
The Isolator & Polarization Beam Combiner/Splitter can be used either as a polarization beam combiner to combine light beams from two PM input fibers into a single output fiber, or as a polarization beam splitter to split light from an input fiber into two output fibers of orthogonal polarization states.
We offer a large selection of hybrid ISO+PBS/C device. These devices can handle powers rang from 300mW to 10W or others on request, and have center operating wavelengths ranging from 1064 nm to 2050nm.
If you do not see a standard Polarization Beam Combiner/Splitter that meets your needs, we welcome the opportunity to review your desired specification and quote a custom Polarization Beam Combiner/Splitter. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.
