Zero order waveplate is a quarter or half-wave retarder made from two plates of quartz within
their fast axes crossed. The difference in thickness between the two
plates determines the retardance. Zero-order retarders provide
accurate retardance over a broad range of wavelengths and are more
durable than single element retarders.
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 application.
