Anyone know why there isn't an article on Wikipedia on polarized light microscopy?
It is listed at PLM:
http://en.wikipedia.org/wiki/PLM
But is not even linked as a redlink.

There is a redirect created four years ago:
http://en.wikipedia.org/w/index.php?title=Polarized_light_microscope&red...
That may have made it less obvious that an article is needed.
And yes, I know the answer is "because no-one has written one yet", but I thought I'd throw this out there and see what happens!

Are you talking about [[Differential interference contrast microscopy]] or [[Interference reflection microscopy]]? Both appear to require polarized light.

Yeah, but I think all three are different, not that I claim to know the difference.

The reason I linked to the www.microscopyu.com article on confocal microscopy was because they mention 'Interference reflection microscopy'. To give a flavour of the different techniques and modes and instruments (I always get terribly confused when trying to work out what is meant by all these different terms), here are a few quotes:
"Both the laser scanning confocal microscope (LSCM) and the Nipkow spinning disk microscope can be utilized in confocal reflection mode."
"A traditional biological application of widefield reflected light imaging is for observing the interactions between cells growing in tissue culture on glass coverslips using a technique termed interference reflection microscopy."
"Presented in Figure 2 are interference reflection digital images captured with confocal reflection microscopy techniques."
"Recently, using a related technique, improved images of filopodia were collected from PC12 cells (rat pheochromocytoma) by growing the cells on a more reflecting substrate. The technique, termed backscatter-enhanced reflection confocal microscopy, produces images that resemble those collected using traditional differential interference contrast (DIC) microscopy."
I gave up at that point... (actually, the site does explain things in a rather accessible way, so let that put anyone off).
One of the applications of PLM is analysing rock samples:
http://en.wikipedia.org/wiki/Petrographic_microscope http://en.wikipedia.org/wiki/Optical_mineralogy
Those articles contain PLM images and talk about the technique, so I was right to think that there is something somewhere about this. Not quite sure why the redirect AGK pointed out (which was moderately valid) was deleted three years ago, but the editor is still here so it is possible to ask. I guess one reason would be that there is more to PLM that just the geological applications.

They're different. Polarized light microscopy is the oldest and basic one. There is indeed more than the geological applications, but for the ordinary technique the geological application are by far the most important. Excellent (non-free) article at Nikon's site, http://www.microscopyu.com/articles/polarized/polarizedintro.html and a briefer one at Olympus' http://www.olympusmicro.com/primer/techniques/polarized/polarizedhome.html I consider them an adequate basis for an article.

Seems to simply not exist yet. It did exist as a redirect at one point but it's gone now:
