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 brod bandwidth
and a lower sensitivity to temperature and wavlenght changes.
Cemented Zero-Order Waveplate
This type of zero order waveplate is constructed of two multiple order
waveplates with their axes crossed. Thus, the effect of the first
plate is canceled by the second, except for the residual difference
between them.
