A–C Peak intensity of PTFE at 739 cm−1 through 8, 14, and 20 mm of polypropylene (PP) at 0–10 mm spatial offsets (1 mm increments). D–F Comparison of signal-to-noise ratios from each probe through 8, 14, and 20 mm of PP at 0–10 mm spatial offsets (1 mm increments). Spectra were acquired using a 4 s integration, 5 acquisitions, 785 nm laser, 500 mW laser power.
