Conformity Check of Thickness to the Crystal Plate 𝜆/4(𝜆/2)

Figure 2

The orientation of the optical axes of crystal plates in relation to the planes of polarizer and analyzer transmission. P = transmission plane of polarizer; A = transmission plane of analyzer; 𝑧₁,𝑧₂ = optical axes of the first and second crystal plates, respectively; 𝛼=𝛾=45^∘; 𝛽=90^∘.
