RT Journal Article T1 Optimal achromatic wave retarders using two birefringent wave plates: reply A1 VilasPrieto, José Luis A1 Sánchez Brea, Luis Miguel A1 Bernabeu Martínez, Eusebio AB This reply attempts to cast some more light on the achromatic systems composed by wave plates, in particular to the calculus of the overall retardation and the use of the Jones matrix equivalence theorem. An equivalent expression for the overall retardation of the system in terms of the trace is also given PB The Optical Society Of America SN 1559-128X YR 2013 FD 2013-10-13 LK https://hdl.handle.net/20.500.14352/33594 UL https://hdl.handle.net/20.500.14352/33594 LA eng NO © 2013 Optical Society of America.
