Estimation of the minimum achievable reflectance of broadband anti-reflection coatings
Fig. 1. Schematic representation of AR performance in a broadband spectral range.
Here you can estimate minimum achievable reflectance of broadband AR coatings (ratio of right and left boundaries of the operating AR range is larger than 2; s-polarization case). Please input parameters required for calculations.
Boundaries of the AR wavelength range: λl = nm λu = nm
High and low refractive indices: nH = nL = Substrate refractive index: ns =
