Microspectrophotometric (MSP) results from the eyes of seven persons. Four kinds of spectra were obtained with absorbance peaks at the following wavelengths: rods, 496.3+/-2.3 nm (n=39); red cones, 558.4 +/- 5.2 nm (n=58); green cones, 530.8 +/- 3.5 nm (n=45); and blue cones 419.0 +/- 3.6 nm (n=5). Data from Table 2 of Dartnall, Bowmaker & Mollon (1983).
