WebWaveplates are commonly made using quartz, mica, or plastic sheets that are stretched to produce an anisotropy that gives rise to birefringence. At visible wavelengths, ne − no ∼ 0.009 for quartz, and the corresponding zeroth-order ( m = 0) quarter-wave plate thickness of ∼40 μm poses a severe manufacturing challenge. WebWaveplates are thus manufactured to work for a particular range of wavelengths. The phase variation can be minimized by stacking two waveplates that differ by a tiny amount in …

"WebValue of mλo can be considered as the retardation and expressed in fractions of a wavelength. For example, m = 1/4 for a quarter-wave plate, and m = 1/2 for a half-wave plate. In term of phase difference: one beam is delayed from other by π/2 in quarter-wave and by π in half-wave plates. " - How do waveplates work
