Better performance than low or multiple order waveplates. The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performance than multiple order waveplates. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications.

Zero Order Waveplates - Cemented by Epoxy This type of zero order waveplate is constructed of two multiple order waveplate with their axes crossed.Thus,the effect of the first plate is canceled by the second, except for the residual difference between them. | |
