The optical isolator is composed of a polarizing beam splitter prism and a quarter zero order wave plate. The optical axis of the wave plate is 45 degrees. The transmitted p-polarized light turns into circularly polarized light after passing through the wave plate. After being reflected, it turns into s-polarized light again through the wave plate, so it is reflected by the polarization splitter prism to achieve the isolation effect.
