Probe for reflectance measurement. The fibers in the outer ring of the common end are from the input SMA connector; The fibers making the center core lead to the output fiber slit. Light is sent down the outer ring for even illumination of the sample. The reflectance is collected by the center core of the fibers and transmitted to the monochromator.
