Waveplates / Zero-Order Waveplate

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.
