Beam Separator
In the beam separator, the P-polarization state is transmitted through the beam-splitting cube, and the beam is converted to circular polarization due to the attached waveplate. Reflecting the beam results in the S- polarization state, which is then directed at 90 degrees out of the face of the laser line beam cube.
