The CIR-1310-50-APC fiber optic circulator is a passive, polarization-independent, three-port device that acts as a signal router. Light from the input fiber is directed to the output fiber, but light returning through the output fiber gets redirected to a third port with virtually no loss. Light input into port one will not be coupled into the port three fiber, and light input into port two will not be coupled into the port 1 fiber. The CIR-1310-50-APC was chosen as an OCT-proven broadband circulator due to its flat spectral response over the entire operating range. This component enables balanced detection at the optical output of an OCT interferometer.

stephan.stuerwald (posted 2016-03-29 17:03:56.943) Dear Sir or Madam, would a customized broad band circulator be possible which covers 1060 plusminus 50 nanometer? What would be the additional cost? Regards Dr. Stephan Stuerwald besembeson (posted 2016-03-30 04:21:47.0) Response from Bweh at Thorlabs USA: I will follow-up with you regarding this custom item.
