Product Description: Waveplates are made from birefringent materials such as quartz crystal and magnesium fluoride with the optic axis in the surface plane. When a linearly polarized beam enters a waveplate, the linearly polarized beam is resolved into components projected along the fast axis and the slow axis. The two components experience a relative phase retardation which is given by:
where d is the thickness of the waveplate; no and ne are the refractive indices of o-ray and e-ray; λ is the wavelength.
When phase retardation is a nonzero value, the waveplate transforms polarizations from one state to another. The thickness of a true zero order λ/2 phase retardation quartz waveplate in the visible spectrum is around 25 µm. Such a thin component is difficult to handle. One solution is to create "multiple order" waveplates with phase retardation equal to (m+1/2)•λ where m is an integer. The integer part of the retardation has no direct effect on the performance of a waveplate. However, because the integer part constitutes most of the overall retardation, it increases the sensitivity of the part's effective retardation to temperature or wavelength variation.
