Thanks for the explanation! The flipping of the handness of the circular polarization (from L to R or R to L) is something I have thought about, and that is why I think the figure shows the circular polarization wrongly. The question now is why after QWP the linear polarization is perpendicular...

Thanks for the reply. There are quite some occasions where this optics configuration is used, see, for example: 1) The picture is from Figure 14 in this link: https://www.edmundoptics.com/knowledge-center/application-notes/optics/understanding-waveplates/ 2)...

In optics experiments, I often see the following optics configuration to rotate the polarization of an incident linearly-polarized laser beam. The final reflected beam has its polarization rotated by 90 degrees. My question is: 1) Between the quarter plate and the mirror( reflecting surface)...
