We have compared the circularly polarized x-ray flux obtained from an elliptical multipole wiggler to that obtained from a planar undulator combined with phase retarding crystal optics. This comparison is carried out for low (3.5{endash}13 keV) and high (50{endash}100 keV) x-ray energies. For both these energy regimes, we demonstrate that phase retarding crystal optics are not only a viable alternative to specialized insertion devices but in some cases provide a superior source of circularly polarized x rays. {copyright} {ital 1996 American Institute of Physics.}
