Hello good morning, thank you very much for your comment, they are indeed "retarders", it is transparent polystyrene, in this case I have used a small container where there were pushpins, you can also use the plastic petri dishes that are also made of this material.

Ret would be retarders/waveplates right? What's the one you use?
