Figure 2: Spectral properties of human Müller cells.
(a) Light concentration factor inside a Müller cell, M(λ), exhibits a wavelength-dependent enhancement with a maximum of 11-fold for 560 nm. (b) Normalized light intensity tunnelling inside a Müller cell (purple circles) is compared with the normalized absorbance spectra of the three spectral types of human cone photoreceptors3,25,26. (c) Calculated spectrum of light leaking out of the Müller cells and illuminating the surrounding area, normalized by a uniform illumination, S(λ). The intensity is reduced by a maximum of ~40% at ~560 nm, while for blue (λ<500 nm) light the reduction is only by ~15%. (d) Normalized light intensity leaking out of Müller cells (black circles) is compared with normalized rods’ absorbance spectrum (brown)25.
