I have been a professional in this area for over 30 years, and would be happy to take this on if there is no-one else willing. As I have only just joined Wikipedia, I will need some time to get used to it. My first reaction from looking at the current article is that it does need comprehensive rewriting although parts of it can be reused. LarryJayCee 22:54, 25 February 2007 (UTC)
- Welcome to it. Ask here if you need help figuring out how to do things wiki-style, or whatever, and some of us will be glad to help, I'm sure. Dicklyon 23:17, 25 February 2007 (UTC)
- Please Larry - fill yer boots! This is, as it stands, a truly bad article because it was lazily grafted here without any thought of context. Having tried to read it myself, I would recommend starting from scratch. Please contact me if I can help with any subsections or in any other way.Rbowman (talk) 14:48, 27 February 2008 (UTC)
- One change I recommend in the rewrite: since many of the Seidel aberrations have individual articles, this article should summarize them, but reserve the details for the individual articles. Instead, this article should focus on the big picture, going into detail on topics not covered by other articles. I can help with formatting and Wikification, but am not an expert in this area.--Srleffler (talk) 18:54, 27 February 2008 (UTC)
This page is almost completely lifted from Project Gutenberg. Because Gutenberg is public domain, this is not a copyright problem, but the original text dates to 1911, without changes. An expert is needed to check the current accuracy of the article.

This is good stuff, but needs cleaning up.
Does anyvone have the images that belong to this article?
- I have obtained a copy of the original (with diagrams), and I suppose I could re-draw them, they're not too complicated. OTOH, I really dislike the style of this article; I'm thinking your idea of splitting off the aberration section of lens is a good one, and expanding that to replace this article. -- DrBob 22:50 Jan 29, 2003 (UTC)
- Just scanning them would be much better than nothing.
I've added the scans from the original article. Not good quality, but if and when someone re-writes this, they should come in useful. -- DrBob 21:21, 15 Mar 2004 (UTC)
filter into separate articles?
There are already specific articles on some types of aberations, such as Coma and Spherical. Maybe this should be more of a summary, and the info used to supplement/enhance their repsective articles. Tenfour 20:51, 15 February 2006 (UTC)
- I agree. The individual articles need to be improved/cleaned up, and then this article needs to be edited to provide a good summary and overview. There is a lot of material that will probably remain here, however. Many aspects of aberrations are best treated together.--Srleffler 07:03, 30 March 2006 (UTC)
This page, at first glance, is a bit much. It really has a great deal of content, but it is so heavy that it is nearly unreadable.RSido 04:41, 2 January 2007 (UTC)
I have never seen the word Pencils used in the context that is is on this page. Sometimes i think that it means angles and sometimes i have no idea what it is referring to. Is this how the original (Gutenburg) article is written or is this a vandalism of sorts? -- Straha_206th 18:19, 9 February 2007 (UTC)
- See if this book page helps: Dicklyon 00:55, 10 February 2007 (UTC)
The drawing 386px-ABERR4.svg is not correct. The radial distortion inreases or decreases with the the distance to the centre of distortion. If it decreases the result is a barrel. So the distorted barrel have to be smaller than the object. Someone with the privileges could change it. --Msoon1509 (talk) 12:14, 17 May 2009 (UTC)
The article discusses fitting a wavefront with a Zernike polynomial. This sort of makes sense, but I'm not clear on how the wavefront would be described. Ideally, a wavefront converging on the image surface would be spherical so that it comes to a point on the image surface. Is the idea that you compute that nearly-spherical wavefront in spherical coordinates? That is, do you look at the chief ray 1mm away from the image and then normalize the rest of the wavefront with ρ in [0,1] representing the angles from the center to the edge of the exit pupil as seen from the image point, so then you ideally would have
(a section of a perfect sphere) and so the aberration is the error,
Is that basically right, or is it something else? I ask because my understanding is that the DC Zernike term corresponds to Piston (optics) and that page does an awful job explaining. If what I describe is correct, then the DC Zernike term is just defocus, no? —Ben FrantzDale (talk) 12:30, 30 May 2012 (UTC)
