WebMar 31, 2024 · This example describes how to construct an effective zero-order retarder with a λ/4 phase change, also known as a quarter-wave plate, which will convert linearly polarized light to circularly polarized light. It utilizes the birefringent material quartz and a HeNe laser (632.8 nm). Generally, the retardance of the plate is given by: 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
