Plate beamsplliters are available with nominal split ratios of 30/70, 50/50, and 70/30. These ratios assume that the incoming beam is randomly or circularly polarized with equal parts of s and p polarization.
If the beam is randomly polarized, the split beams will be linearly polarized (weakly). If the incoming beam is circularly polarized, the split beams will be elliptically polarized.
