4. This is a bifurcated fiber optic bundle, with each arm containing one 100 μm diameter fiber. The fibers are encased in a 1 mm diameter s.s. hypodermic tube for the last few inches at the shell end, and separated only by their cladding at the end. As a result, light source and spectroscopic detector are both focussed on the same spot.
