Fig. 8. Excitation and emission spectra in the porcine retina.

Fig. 8

a Freshly prepared vertical section of a live pig retina showing the locations used to measure emission spectra presented in b. b Emission spectra in the different retinal layers showing a peak at 550 nm under a 475 nm laser excitation source. c excitation–emission matrix on a cone inner segment exposed to wavelengths ranging from 300 to 490 nm in 15 nm increments. POS: photoreceptors outer segments, PIS: photoreceptor inner segments, ONL: outer nuclear layer, OPL: outer plexiform layer, INL: inner nuclear layer, IPL: inner plexiform layer, GCL: ganglion cell layer, OFL: optic fiber layer.
