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.
The information I need is the power distribution for wavelengths across the visible spectra in 5 to 10 nm increments. I would like to have both the numerical values and also a graph showing this power distribution.
Is anyone aware of where I can find this information ?
Thank you in advance,
Joseph.

These datasets float on a few servers around the world. San Diego University Color Vision site is one source I know who has them. The Munsell Color Science Institute is another site which I used in the past that I remember has them.

Hi, everyone.

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

Hi does anyone know if there are figures for an approximation for generic flash? Just for a comparative graph
