Talk:Schmidt corrector plate

"Schmidt corrector plates do not compensation for the lack of magnification? which non-parabolic reflectors experience. "

This seems to be nonsense to me. Since I don't know anything about telescopes and hit "random", I don't know which way to fix it :)

Either they do compensation or they do not do compensation or do not compensate. Anyone?

This seems like nonsense because it is (my apologies to Pizza Puzzle, please don't take it personally).

Originally:

This "plate" is actually a lens which refracts the light after it has been reflected by the mirrors. Schmidt corrector plates do not compensate for the lack of magnification which non-parabolic reflectors experience.

Light passes throught the Schmidt corrector before it reaches the primary mirror and magnification is strictly a function of focal length. Fixing now. Rsduhamel 03:09, 1 Jan 2005 (UTC)

I removed the word "magnification" because it is irrelevant in this context. magnification is a ratio of eyepiece focal length divided into objective focal length. So theoretically any given focal length can have any magnification. 69.72.93.228 01:30, 11 December 2006 (UTC)[reply]

Figure it out?

What does it mean to "figure" a lens or a mirror? Please rewrite for laypeople. Also, a diagram of the corrector plate with some light ray paths, compared to an uncorrected spherical mirror, would be really helpful if available. - Frankie 20:21, 5 January 2007 (UTC)[reply]

I have replaced the jargon term "figured". There is a little information on these processes at Fabrication and testing (optical components) but it isn't much. 69.72.2.72 01:01, 3 April 2007 (UTC)[reply]

The jargon term "unfigured" remains, however. 83.104.249.240 (talk) 04:26, 25 February 2009 (UTC)[reply]
