A compensated higher order waveplate is constructed of substrates. In one embodiment, a first substrate is a nλ waveplate and the second substrate is a (n+Δ)λ waveplate. The substrates are oriented so that their principle axes of retardation are orthogonal. nλ is a base retardation of a waveplate and Δλ is an incremental retardation. The incremental retardation produces a desired amount of retardation of a lightwave passing through the compensated higher order waveplate. Retarder material used to produce the base retardation is approximately ½ a desired thickness of the waveplate. Multiple waveplates are combined to produce any of wavelength band specific retarders and multiple non contiguous wavelength band specific retarders.
