For effective measurement of fluorescence, Avantes offers this specially designed reflection probe. It features 12 excitation fibers of 200 μm around a 600 μm read fiber, which transports the fluorescence signal back to the spectrometer.
To turn the 45° reflection probe into a fluorescence probe, a special reflector accessory, FCR-FLTIP-IND, is attached to the probe end. It prevents ambient light to enter the probe and backscatters the excitation light. This increases the typically low
