Summary

[edit]
Description
English: Airy disk and pattern from diffracted white light (D65 spectrum). The color stimuli have been calculated in the CIE 1931 color space and then converted into sRGB. Apart from the sRGB definition there is a moderate additional gamma correction of 0.7 0.8 to enhance brightness in the outer rings. This may cause a slight but acceptable distortion in colours, however.
