File:Barlow_02.png[edit]

Hi Tamasflex, in formula 1 brackets arround the denominator are missing (cf. 2, 2' ). Perhaps it's possible to correct the illustration. An other topic is the focal length of the Barlow lens. As the Barlow lens is a divergent lens, the focal lens is negativ, i.e. f bar.=- 50 mm or - f bar.=50 mm but not - f bar.=- 50 mm. Thanks for your great work -- 85.180.63.151

Steinheil Monocentric[edit]

Dear Tamasflex, thanks for providing a sketch of the Steinheil Monocentric. I have added a comment to the effect that your image does not actually show, however, that all lens surfaces share a common center point. THe is a historic image on commons that nicely depicts this feature. Best regards, --Trinitrix (talk) 05:02, 23 July 2010 (UTC)

Thick lens[edit]

ThickLens

Thank you for your image of a thick lens. I have gone over the algebraic notation and identified most of them specifically, but am having trouble identifying the item e. Can you tell me what this dimension is called? Thank you. KDS444 (talk) 03:39, 20 November 2012 (UTC)
