Hi, everyone.
I am looking for both a graph and numerical values of the SPD (spectral power distribution) of illuminants D55 and D65 but haven't had much luck.
Joseph, These values were taken from "Illuminations.cxf", a file included with Eye-One Share. The data is in "lambda - Power" format - not sure why the D65 has more decimal places. D55 380 - 32.58 390 - 38.09 400 - 60.95 410 - 68.55 420 - 71.58 430 - 67.91 440 - 85.61 450 - 97.99 460 - 100.46 470 - 99.91 480 - 102.74 490 - 98.08 500 - 100.68 510 - 100.7 520 - 99.99 530 - 104.21 540 - 102.1 550 - 102.97 560 - 100.0 570 - 97.22 580 - 97.75 590 - 91.43 600 - 94.42 610 - 95.14 620 - 94.22 630 - 90.45 640 - 92.33 650 - 88.85 660 - 90.32 670 - 93.95 680 - 89.96 690 - 79.68 700 - 82.84 710 - 84.84 720 - 70.24 730 - 79.3 D65 380 - 49.9755 390 - 54.6482 400 - 82.7549 410 - 91.486 420 - 93.4318 430 - 86.6823 440 - 104.865 450 - 117.008 460 - 117.812 470 - 114.861 480 - 115.923 490 - 108.811 500 - 109.354 510 - 107.802 520 - 104.79 530 - 107.689 540 - 104.405 550 - 104.046 560 - 100.0 570 - 96.3342 580 - 95.788 590 - 88.6856 600 - 90.0062 610 - 89.5991 620 - 87.6987 630 - 83.2886 640 - 83.6992 650 - 80.0268 660 - 80.2146 670 - 82.2778 680 - 78.2842 690 - 69.7213 700 - 71.6091 710 - 74.349 720 - 61.604 730 - 69.8856 HTH - Steve
