Multiple order plates are more dependant on the temperature changes than zero order plates. A change of +- 1% from the designed wavelength of multiple order plate can result in difficulties in retardation. Contrary, with zero order plates +-1% and even +-2% change from designed wavelength can cause only small retardation change.
