A natural extension for magnetospectroscopy is to sense circular dichroism, i.e. the difference in a material's optical response for left and right circularly polarized light. A key component for spectroscopic circular dichroism is an achromatic 1/4 wave retarder functioning o","authors_text":"A.A. Sirenko, G.L. Carr, J.J. Tu, R.J. Smith, S.N. Gilbert, T.N.
