Title: Light polarization set up
Post by: kensher on November 06, 2019, 05:01:09 AM

Hello!

I am working with enantiomers in organic chemistry, and there is this one picture from the book which I don't fully understand. The picture is attached.

There are supposedly two lenses that are perpendicular to each other. I assume this is the two almost-transparent discs which overlap in one area. However, I don't understand what the black device is or what its purpose is. Can somebody please explain this to me?

Thanks in advance.

Very poor example (and poorly drawn). It tries to say more or less the same thing this video shows: https://www.youtube.com/watch?v=MhhHPOxTUy8
