Does anyone know the history of the condenser lens? There seems to be a lack of information about its history and its manufacturing. Is it a glass blowing technique? -- kanzure (talk) 00:02, 5 September 2009 (UTC)
- I think the manufacturing technique depends on the quality of the microscope. From what I've seen, the cheap microscopes sold in discount stores for children use moulded plastic; research-quality microscopes have what look like ground lenses. --Jc3s5h (talk) 00:10, 5 September 2009 (UTC)
i just read the article on dark field microscopy and this article suffers from the same thing. If you don't know what any of this is, it doesn't help to read these articles. T thought that a condeser lens took parallel light rays from an illumanated object and focused them to a point for the eye piece to examine. That isn't what i'm getting from this explanation. I'm not smart enough to rewrite this, but i think it could be improved somewhat.Longinus876 (talk) 21:41, 14 June 2010 (UTC)
Other (optical) condensers?
I arrived at this article via an interwili link form the Dutch Wikipedia. Most language editions have one article on optical condensers, treating the aspects for several applications (projectors, microscopes, etc.)
Considering that projectors are much better known to the general public (our "customers"!), I wonder why I do not find any reference to (or treatment of) e.g. projector condensers.

I agree with the above comment that there should probably really be one article that covers optical condensers, including the use in microscopy. Such an article would probably belong at condenser (optics) and should retain all this excellent material, but with a broader lede and some discussion of other applications.
