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. 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 …
