Waveplates use a phenomenon known as birefringence to alter the incoming laser beam polarization state. The most common waveplate uses are for turning linearly polarized light into circularly polarized light (quarter-wave plates), and to rotate the polarization plane of a linearly polarized source (half-wave plates).

II-VI manufactures both multiple order and zero order waveplates. Zero order waveplates have the dual advantage of being less sensitive to changes in operating temperature and input wavelength.
