Description
A zero-order wave plate delivers its design retardance, for example λ/2 or λ/4, without the extra whole waves of a multi-order plate. Its retardance therefore changes far less with wavelength and temperature. A λ/2 plate rotates linear polarization; a λ/4 plate turns linear into circular polarization. Uses include laser systems, spectroscopy and telecommunications.
