Second one is really nifty.

Wonderful images!

I was interested to read about Chaoborus in http://en.wikipedia.org/wiki/Glassworm and in the link at the bottom of that article.

Excellent pol images!
What kind of compensators did you use in the second image?. It looks very similar to the third one but without the magenta background.

Thanks, the left one is a full wave plate (red ,tint, gypsum...) and the right one a 1/4 wave plate (mica...).
What surprises me a bit is that the interference colors of the specimen are about the same with both plates

Indeed, they are very similar but differ

Very nice!

Thanks for the shot of the compensators. I too was wondering how the magenta background was "removed".
