MULTIMODE CIRCULATOR/COMBINER
Castor Optics’ Wideband Multimode Circulator (WMC) is a three-port device that features a flat spectral response, high efficiency multimode transfer (Port 1 ⟶ Port 2), and multimode transmission (Port 2 ⟷ Port 3). It can be used to combine multiple signals or illumination/detection channels within a single fiber. Castor’s all-fiber WMC series is an efficient, versatile, and robust solution for multimode light management with applications in diffuse reflectance spectroscopy, fluorescence spectroscopy, and/or optogenetics.
