Go!Foton’s Visible Wavelength Fused Coupler utilizes Fused Biconical Tapering Technology to create a composite waveguide structure capable of splitting or combining light in the visible
region (400 to 700nm). This device is suitable for biomedical system applications like confocal and fluorescence microscopy, flow cytometry and others. Fiber ports can be made as input/output fiber pigtails or connectorized which can be directly integrated into beam delivery systems.
