Figure 2. — Optical characterization of the oil droplets of single cone photoreceptors. (a) Absorption coefficients of the four single cone types: dashed lines are the measured absorption coefficients; solid lines are the simulated absorption coefficients based on Lorentzian dipoles. (b) Refractive index of single cone oil droplets: solid lines are the simulated dispersion curves based on Lorentzian dipole absorbers; filled circles are the mean values from DHM measurements. Red cone, red; green cone, green; blue cone, blue; violet cone, violet.
