Dual/Harmonic Waveplates	Dual/harmonic waveplates are designed so that a defined phase shift can be reached for two wavelengths. The retardation can be selected differently for each single wavelength. In this way, the wavelength λ = 1064 nm, for example, can go through a phase shift of λ while the second wavelength, λ = 532 nm, experiences a phase shift of λ/2. The retardation plates otherwise correspond to multiple order plates.
Low order	0.1 mm - 0.25 mm
Multiple order	0.4 mm - 0.6 mm
There are three main types of waveplates	multiple order, low order, and zero order. The fundamental difference between these plates is the stability of the retardation tolerance across the wavelength range λ. This tolerance is a function of spectral range, product type, and design thickness.
