Zero Order Waveplate
Zero order waveplate is constructed by two quartz plates with their fast axis crossed. The difference in thickness between the two plates determines the retardance. Zero order waveplates offer a substantially lower dependence on temperature and wavelength change than multi-order waveplates.
