Achromatic waveplate is similar to Zero-order waveplate except that thetwo plates are made from different materials, such as crystal quartz andmagnesium fluoride. Since the dispersion of the birefringence can be differentfor the two materials, it is possible to specify the retardation values at awavelength range.
