I have moved photographic lenses into their own category, and moved other types of lens from category:optics and category:optical devices into this category.-- Srleffler 18:20, 22 October 2005 (UTC)
I was just wondering some things...
what is a lens called that is used specifically for heating objects? Is that a practical use? Are there manufacturers of such lenses?
thanks :)

I'm wondering if we need to migrate the current children of this category into one called 'Optical lenses' given the existence of non-optical ones like this. Ditto for the lenses used in electron microscopes. Hooperbloob ( talk) 21:20, 25 January 2009 (UTC)
