Optical thickness formula
WebFeb 20, 2012 · Optical thickness depends on the physical constitution ( crystals, drops, droplets ), and the form; the overall effect depends on the scatter parameter and the … WebIn order to maximize or minimize interference, they are typically λ/4 optical thickness (QWOT) or λ/2 optical thickness (HWOT) of the wavelength of the light used in the application. These thin film layers alternate between high index of refraction and low index of refraction, thereby inducing the interference effects needed ( Figure 1 ).
