Hello,
Wondering if anybody can help me. Can 2 quarter wave plates be used as a half waveplate, to rotate the plane of polarization? Thank You

Can 2 quarter wave plates be used as a half waveplate, to rotate the plane of polarization? Yes. You can use two quarterwave plates, installed one after another. Just keep their pricipal axes parallel to each other: slow to slow fast to fast. This is critical condition for the adding of wave shift
