If I have a retarder, where do I put it?
Please no technical notes about optics or wave plates. I'm just trying to understand how to use a retarder.
Thanks,\
Mary

Somewhere between the polarizer and analyser.

I think it goes between the specimen and the analyser. On my BX50 it sits under the analyser and may be slid in/out.

By design yes but you get the same effect if you put it between the polarizer and specimen.

Some setups put it right above the polarizer, some right below the analyzer.

Thanks to you all.
So many articles and posts that mention retarders do not have a clear explanation for beginners. I truly appreciate your quick and simple responses.
