WebQuarter-Wave Plate. A quarter-wave plate consists of a carefully adjusted thickness of a birefringent material such that the light associated with the larger index of refraction is retarded by 90° in phase (a quarter wavelength) with respect to that associated with the smaller index. The material is cut so that the optic axis is parallel to the front and back … Webexample, 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. The phase difference δ is . δ = 2πm = 2π d(n. e - n. o) / λ. o (5) In a positive uniaxial crystal n. e > n. o
