[edit] Photreceptor spacing
"The smallest f-number for the human eye is about 2.1. The resulting resolution is about 1 micro meter. This happens to be about the distance between optically sensitive cells, photoreceptors, in the human eye."
I dispute this, foveal cones are typically 1.5μm in diameter with a 0.5μm gap between each, thus giving the array a 2μm spacing. However this may not be the case for the entire retina so I will leave the article until someone more knowledgeable can confirm this —The preceding unsigned comment was added by 131.251.0.55 (talk) 22:29, 6 May 2007 (UTC).
I'm no eye expert, but it would make sense to have a 2µm spacing, as in visible light, directly applying the equation just before this statement, the airy disk is about 1µm, that's true, but for 400nm. The airy disk would then vary between 1µm and 1.8µm in the visible spectrum (taken here between 400 and 700nm). Then again, we would have to take into account the repartition of the three different cones... Palleas 14:37, 15 May 2007 (UTC)
[edit] Spherical Aberration Image
Might this be better placed in the article on lens aberrations? neffk (talk) 15:12, 22 April 2008 (UTC)
