The drawback of multiple-order waveplates is the rapid change in retardation as the wavelength varies. For a small change in Δλ (or equivalent change in temperature), the multi-order waveplate shows a large transmission change ΔTmulti. By contrast, the change in retardation of the zero-order plate is very slow, so the same Δλ gives a much smaller change, ΔTzero
