The 78373 Fluorescence/Reflectance Probe carries light to the sample via the 6 individual 400 μm fibers, and the signal is collected and delivered to the spectrometer via the center fiber. This off-the-shelf item is used for reflectance or fluorescence measurements from solid samples. Upon request, we can offer 30° angled probes for reflectance of highly translucent solid samples (where 2nd surface reflections are a concern), or for solutions measurements. This Solarization Resistant version is 2 m in total length, with the common end is 1 m long, and the legs 1 m long.
