Quartz Waveplates,Multiple Order waveplates
Multiple Order waveplates(Low Order Waveplate) are made so that the relative phase change is larger than the required value by an integer multiple of 2π. While the performance at the design wavelength can be essentially the same, chromatic dispersion has a stronger effect for thicker plates, so that the optical bandwidth in which the plate has roughly the correct relative phase change is limited. Also, the retardance has a higher temperature sensitivity.
