Non-absorbing fibres (R = 5 µm, n = 1.477; R = 10 µm, n = 1.478) under a Cassegrain (NA 0.1–0.4): transmission, Davis, Carney & Bhargava 2011, Fig. 5 Davis, Carney & Bhargava, Anal. Chem. 83, 525 (2011): a fibre that absorbs nothing still shows a strong, wavenumber-dependent apparent absorbance, made by refraction and scattering out of the objective. Values read off Fig. 5 to ±3%; the paper prints no position for the maximum and the dip, so they are marked where PyStratify's curve turns, and the minimum sits 20 cm⁻¹ from the read 1100. The paper does not state Fig. 5's NA; 0.1–0.4 is its Fig. 2 pair. From crosscheck/classics/davis_2011.py.
