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.

1. Zero Order Waveplates-Optically Contacted This type of zero order waveplate is constructed of two low 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.
