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

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.
