Is the bifurcated fiber assembly used only to connect the probe to the instrument and excitation source, or is the probe itself a bifurcated optical fiber?
There are several probes available as off-the-shelf items, and others available as custom designs. The standard probe — the “-R” Probe — is a 1 mm diameter, silica-core, silica-clad fiber in a 1/16″ OD stainless steel ferrule. The tip is polished at a 30-degree angle and is coated with the sensor formulation. The other end is terminated with a standard SMA connector. This probe couples to a bifurcated 600 um diameter fiber with 1 leg used for excitation and the other for bringing the fluorescent signal to the spectrometer.
